ABSTRACT:
A low power switched diversity antenna system (200) includes two varactor tuned antennas (205, 207), each including an antenna element (505) and a varactor (515). The varactor tuned antennas intercept components of electromagnetic radiation that are substantially orthogonally polarized. One of the varactor tuned antennas is tuned to a desired frequency and the other is detuned, achieving a relative gain of the tuned varactor tuned antenna to the detuned varactor tuned antenna of at least 3 dB at the desired frequency.
