Dual-antenna system for single-frequency band

摘要

A combination satellite and terrestrial antenna system for a single-source application. A first embodiment includes a cross dipole for receiving the circularly polarized satellite signals, and a plurality of monopoles for receiving linearly polarized terrestrial signals. The mono-poles are arranged symmetrically about the cross dipole. Alternative embodiments include a helix antenna for receiving the satellite signals, and one or more linear antennas arranged symmetrically with respect to the helix for the terrestrial signals.
