  • Hom antennas play a crucial role in fixed wireless access (FWA) networks.
  • FWA fixed wireless access
  • CPE customer premises equipment
  • hom antennas are widely used in microwave and millimeter- wave applications for their directivity and efficiency.
  • hom antennas provide enhanced performance in terms of beam pattern, bandwidth, and efficiency.
  • a horn antenna system for a sector-based communication system includes three horn antennas in a 30-degree configuration configured to cover 90-degrees of transmission area.

  • a base station may also refer to a short-range transceiver which connects a cordless phone, computer, or other wireless device, such as customer premises equipment (CPE) devices, to a central hub and allows connection to a network, such as a cellular network.
  • CPE customer premises equipment
  • CPE includes telecommunications and information technology equipment kept at the customer's physical location rather than on the service provider's premises.
  • Telephone handsets, cable TV set-top boxes and Digital Subscriber Line (DSL) routers are examples of CPEs.
  • a base station may also be connected to a sector antenna, wherein the sector antenna is a type of directional microwave antenna with a sectorshaped radiation pattern.
  • a transceiver is a device that can both transmit and receive communications, such as a combined radio transmitter and receiver. It can both transmit and receive radio waves using an antenna, for communication purposes.
  • a horn antenna is used to transmit radio waves from a waveguide (a metal pipe used to carry radio waves) out into space or collect radio waves into a waveguide for reception. It typically consists of a short length of rectangular or cylindrical metal tube (the waveguide), closed at one end, flaring into an open-ended conical or pyramidal shaped hom on the other end.
  • the radio waves are usually introduced into the waveguide by a coaxial cable attached to the side, with the central conductor projecting into the waveguide to form a quarter- wave monopole antenna. The waves then radiate out the hom end in a narrow beam.
  • the radio waves are conducted between the transmitter or receiver and the antenna by a waveguide; in this case the hom is attached to the end of the waveguide.
  • the open mouth of the hom is often covered by a plastic sheet transparent to radio waves, to exclude moisture.
  • a hom antenna serves the same function for electromagnetic waves that an acoustical hom does for sound waves in a musical instrument such as a trumpet. It provides a gradual transition structure to match the impedance of a tube to the impedance of free space, enabling the waves from the tube to radiate efficiently into space.
  • the small aperture of the waveguide causes significant diffraction of the waves issuing from it, resulting in a wide radiation pattern without much directivity.
  • the ends of the waveguide are flared out to form a hom.
  • the taper of the hom changes the impedance gradually along the horn's length. This acts like an impedance matching transformer, allowing most of the wave energy to radiate out the end of the hom into space, with minimal reflection.
  • the taper functions similarly to a tapered transmission line, or an optical medium with a smoothly varying refractive index.
  • the wide aperture of the hom projects the waves in a narrow beam.
  • the waves travel down a hom as spherical wavefronts, with their origin at the apex of the hom, a point called the phase center.
  • the pattern of electric and magnetic fields at the aperture plane at the mouth of the hom which determines the radiation pattern, is a scaled-up reproduction of the fields in the waveguide.
  • the phase error is called the phase error. This phase error, which increases with the flare angle, reduces the gain, and increases the beamwidth, giving horns wider beamwidths than similar-sized plane-wave antennas such as parabolic dishes.
  • a sector antenna is a type of directional microwave antenna with a sector-shaped radiation pattern.
  • the word "sector" is used in the geometric sense; some portion of the circumference of a circle measured in degrees of arc, 60°, 90° and 120° designs are typical, often with a few degrees 'extra' to ensure overlap and mounted in multiples when wider or full-circle coverage is required.
  • the largest use of these antennas is as antennas for cell phone base-station sites. They are also used for other types of mobile communications, for example in Wi-Fi networks.
  • a sectoral hom is a pyramidal hom with only one pair of sides flared and the other pair parallel, where a pyramidal hom is a hom antenna with the hom in the shape of a four-sided pyramid, with a rectangular cross section. It produces a fan-shaped beam, which is narrow in the plane of the flared sides, but wide in the plane of the narrow sides. These types are often used as feed horns for wide search radar antennas.
  • the system described herein includes three 30-degree horn antennas.
  • the system replaces one 90-degree sector antenna with three 30-degree antennas. This substitution enhances terrain coverage, and the higher gain of each individual antenna contributes to an increased signal range.
  • This system is designed to address the goal of reducing the manufacturing cost of high-power solid state power amplifiers by utilizing three 30- degree antennas instead of a 90-degree sector antenna. Additionally, this system is configured to enhance the mitigation of 'interference' caused by a single sector in adjacent sectors.
  • the interconnection of multiple individual power amplifier presents challenges related to losses in system integration (coupling power amplitude modules (PAM)), making it more difficult to dissipate excess heat, such as for Solid State Phased Arrays (SSPAs).
  • PAM power amplitude modules
  • SSPAs Solid State Phased Arrays
  • the antenna system described herein includes a triple 30- degree horn configuration.
  • the antenna system consists of three horn antennas positioned at a precise angle of 30 degrees each.
  • This triple configuration enables the potential for frequency separation within a singular 90-degree sector, created by the three 30-degree antennas.
  • This design results in diminished interference in the neighboring sector and smaller side lobes radiation pattern.
  • the reduced interference in the adjacent sector is particularly noteworthy, as it enhances the overall performance of the system. This configuration allows for improved coexistence with neighboring communication channels and helps maintain signal integrity in complex radio frequency environments.
  • this configuration not only enhances performance but also facilitates a more cost-effective production of the entire communication system.
  • the production cause of the entire radio communication system is significantly lowered, while maintaining the same signal range and coverage as a system with a single 90-degree antenna in the sector.
  • This cost efficiency is attributed to the use of three 30-degree antennas, providing a practical alternative with comparable or even superior results in signal propagation and coverage.
  • the three sector 30-degree antennas are individually designed and positioned in relation to each other so that the three 30-degree antenna characteristics collectively form the overall characteristic of a 90-degree sector.
  • This deliberate arrangement allows for the seamless integration of the individual radiation patterns of each 30-degree antenna, resulting in a cohesive and comprehensive coverage within the broader 90-degree sector.
  • the antennas are made of aluminum. This insures durability and structural integrity, but also ensures the antenna’s low weight. This lightweight construction facilitates easy installation and maintenance, making it a practical choice.
  • the system includes a Beamforming Mechanism.
  • the beamforming mechanism that enables precise control of the radiation pattern at 70 - 71.5 GHz frequency range.
  • the three 30-degree sector antennas are strategically configured to collectively generate a focused radiation beam through beamforming techniques, effectively establishing a 90-degree sector coverage. This serves as a basis for creating 360-degrees of coverage of the terrain for the purpose of using four communication points.
  • the primary objective behind this configuration is to facilitate the deployment of four base stations, strategically positioned to ensure optimal coverage throughout the entire 360° area.
  • the use of beamforming technology enhances the precision and directionality of the antennas, allowing for efficient signal distribution and reception across the designated sector.
  • This configuration not only maximizes the utilization of each sector antenna but also ensures seamless and consistent coverage across the entire terrain.
  • the integration of beamforming techniques enhances the overall performance and reliability of the communication system, making it well-suited for a variety of applications that demand extensive and reliable coverage.
