In some applications, since the receiver may be far from the active antenna, the receiver's supply voltage to the active antenna is reduced, which affects the performance of the active antenna or exacerbates the attenuation of the electrical signal during transmission, or The height of the building is different. The strength of the radio signal is different when receiving and transmitting. It is often necessary to increase the gain of the existing secret receiving or transmitting signal, such as increasing the gain by adding a low-level noise amplifier, gain amplifier or active filter. It is inconvenient to install active n-pieces such as amplifiers, especially for active antennas or active antennas that convert passive antennas. The problem of feeding is a headache for field engineers. The existing method is to connect feeders. To the purpose of feeding the active antenna to the active antenna end, this will bring many problems from the design, construction, scale and f of the series, such as the feeding power and signal power provided by the system can not reach the distance of the scene.

[Embodiment] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In the embodiment of the present invention, a substrate including a feeding circuit is built in the same connector, an external power supply voltage is directly applied to the feeding circuit, or an external power supply voltage is applied to the feeding circuit through an input signal line of the coaxial connector. The cooking circuit can thereby feed the active circuit inside the substrate and the next active circuit of the coaxial connector. The first figure shows the built-in substrate and circuit structure of the coaxial connector provided by the first embodiment of the present invention. The substrate n is a two-layer substrate, the surface layer of which is a circuit layer, and a common ground layer of two layers of bismuth metal material acts as a common grounding end, and the bottom layer is in contact with the housing of the same connector (common ground). On the surface layer of the substrate u, the signal input end 121 of the substrate u is connected to the end of the (radio frequency) DC blocking capacitor 15 via the signal microstrip line 14, and the other end of the DC blocking capacitor 15 is passed through the signal microstrip line 14 and the substrate u. The signal 鱿 禚 相 131 is connected; the substrate η further includes a feeding circuit 16 , the feeding circuit 16 acts as a high resistance to the radio frequency signal to prevent the radio frequency signal, but the DC able to pass. The external power supply voltage is applied to the feed wheel input terminal π of the feed circuit 16, and the feed output terminal 18 of the feed circuit 16 is connected to the signal output terminal 131, 11 200950239 through the signal output end of the coaxial connector Primary (external) active circuit for power generation. The substrate 11 is built in the housing of the coaxial connector, and a single or multi-layer substrate can be used. In particular, the grounding end of the control substrate 11 is kept in common with the housing of the coaxial connector. The second figure shows an implementation of the feed circuit 16 shown in the first figure. Referring to the second figure, the feed circuit 161 is a signal printed on the substrate n. The impedance microstrip line 'external power supply The supplied voltage is applied to the feed input 17' of the feed circuit 161. The feed output 18 of the feed circuit is coupled to the signal output 131. When the letter rate is not high, such as less than 1 GHz, it is also possible to replace the signal 咼 impedance microstrip line with a high-impedance current coil, or to select other signal high-resistance networks depending on the application. In addition, a core-through capacitor can be connected between the feed input terminal 17 and the housing of the coaxial connector to better prevent leakage of the RF signal. The DC blocking capacitor 15 can select the capacitance according to the frequency band of the signal. The DC blocking capacitor 15 in the second figure is a chip capacitor. The second figure is a schematic view of a housing structure of a coaxial connector according to a first embodiment of the present invention, which is a modified SMA type coaxial connector.

The third fiscal_axis connector is a bidirectional connector, the input and output can be interchanged, but considering that the circuit on the substrate u is not a bidirectional circuit structure 'the signal input and the output are not interchangeable, for convenience of explanation and consideration System connection (4) Conventionally, the male end of the towel shaft connection of the embodiment of the present invention serves as the signal input end 12 (of course, there may be other arrangement manners), and the signal input end 121 and the signal output end 131 of the substrate u are respectively soldered thereto. On the internal signal terminals 12, 13 of the same connector, the common ground terminal of the substrate u is in contact with the metal substrate 111 of the housing 12 200950239 of the coaxial connector as the ground terminal of the feed circuit 16, that is, the feed current The grounding end of the circuit 16 can be connected to the system through the metal substrate 111, and kept in common with the system. The feeding input terminal of the feeding circuit 16 is connected to the external power source through the through-core capacitor 114. Of course, a coaxial can also be used. The connector of the connector replaces the core capacitor 114 and can also serve as a feed. The fourth figure is a schematic view of the outer shape of the coaxial connection arc mask provided by the first embodiment of the present invention. The straight edge of the arc mask 110 is hinged to the straight side of the window of the coaxial connector housing shown in the third figure or is connected by other means. The arc mask 11 can be opened. The arc mask 110 has a hole through which the core capacitor 114 can be installed between the hole and the feed input end 17 of the feed circuit 16. The external power source voltage passes through the core capacitor 114. It is applied to the feed circuit. If you want to use a direct power supply (supply voltage) to feed down the active circuit, that is, if the power supply is not shared with the system that needs to be fed, in order to ensure that the external power supply and the system remain in common, The grounding end of the power supply is also connected to the common grounding end of the bottom layer of the feeding circuit 16, for example, a metal grounding piece is disposed between the core-through capacitor 114 and the arc mask, and the grounding end of the external power source and the coaxial connector are The metal ground plane on the arc mask 110 is connected 'to ensure that the external power source and the system's feed circuit 16 have a common ground.

When the signal input terminal 121 and the signal output terminal 131 of the substrate u are soldered in combination with the first to fifth figures, in order to ensure better grounding of the feed circuit 16 and the system, it is prevented that the substrate 11 rises due to the cooling of the solder. The substrate u is not well held in contact with the metal substrate hi, on the side of the substrate u, that is, on the side adjacent to the signal input terminal 121 or the output terminal 131 of the substrate n, on the substrate u and the metal substrate Between 13 200950239 Installation of a grounded metal gasket 119, it is also possible to install two metal gaskets symmetrically, but leave the position of the feeder, such as a slot at the junction with the feed input 17 to prevent the metal Shim 119 is in contact with feed input terminal 17. The metal spacer 119 can be a drum copper. When the internal space of the coaxial connector is relatively large, the substrate 11 can also be fixed to the metal substrate 111 by screws.
