Abstract

A dual mode antenna assembly has a quadrifilar antenna assembly for satellite communications and a monopole antenna for terrestrial communications. The satellite antenna is positioned concentrically around and external to the terrestrial antenna, and has first, second, third and fourth antenna elements. An impedance matching network makes the impedance of the terrestrial antenna located inside the quadrifilar antenna have essentially the same impedance as that of an isolated monopole not surrounded by the quadrifilar antenna.
