摘要： A weather radar antenna for radiating a desired beam formed by feeding quadrants of the antenna uses a dual-mode switched aperture antenna feed. The dual-mode switched antenna feed has an input divider that splits the input signal. A left switch switches the split input signal using a left first diode and a left second diode to top left and bottom right quadrants of the antenna. A right switch switches the split input signal using a right first diode and a right second diode to top right and bottom left quadrants of the antenna. The diodes are forward and reverse biased as required to feed top, bottom, left and right portions of the antenna to obtain the desired beam. When all the diodes are reversed biased the split signal is fed to all quadrants of the antenna.

摘要： A high-isolation polarization diverse circular waveguide orthomode feed apparatus capable of supporting any arbitrary linear, right-hand circular, left-hand circular or elliptically polarized electromagnetic wave with desirable performance over a broad range of frequencies and small size is disclosed. The waveguide feed employs the combination of a circular waveguide segment, stepped septum polarizer, and a novel arrangement of diametrically opposed electric field probes in the bifurcated region of the circular waveguide segment to achieve low crosspolarization when operating in arbitrary linear mode and high-isolation for rejection of undesired cross-polarization components when operating in circular or elliptical polarization mode. This apparatus is an elegant, simple, compact, rugged, and cost effective design that is applicable to a broad family of microwave antennas, but in particular those required to meet minimal radome swept volume requirements.
