Abstract
A pair of adjacent antennas are configured to transmit and receive wideband signals with low direct coupling. The antennas are horns with extended walls and a shaped septum. At a typical operating frequency of 5.8 GHz, coupling levels are as low as -60 dB. Low coupling levels are needed to reduce measurement errors in radar rangefinders operating at less than 1-meter target range.
