摘要： An aperture of an antenna for a radar system comprises a first waveguide comprising a first protrusion and a second protrusion, each protrusion extending longitudinally along one side of the first waveguide. The aperture further comprises a second waveguide comprising a third protrusion and a fourth protrusion, each protrusion extending longitudinally along one side of the second waveguide. The first and third protrusions and second and fourth protrusions adjoin to form a radio frequency choke at least partially suppressing cross polarization of radio frequencies between the first and second waveguides.

摘要： A system and related method is disclosed including a symmetrical array of Balanced Antipodal Vivaldi Antenna (BAVA) elements. Within the array a plurality of dual polarization sub-arrays comprised of individual BAVA elements oriented in a first polarization and individual BAVA elements oriented in a second polarization. The plurality of sub-arrays maintains low mutual coupling and cross polarization rejection between sub-arrays within the array and between elements within the sub-array. As a signal is received by each of the individual BAVA elements, signals from each first polarized BAVA element and each second polarized BAVA element of a sub-array are combined to produce a single signal of the first polarization and a single signal of the second polarization per sub-array. A DF processor receives the two signals and determines the angle of arrival of the signal. A communications link within the array sends and receives information and commands for array operation.

摘要： A parasitic array antenna and a beamforming method for such a parasitic array antenna are disclosed. The parasitic array antenna may include a single driven element at the center of a ground plane. The driven element may be surrounded by multiple parasitic elements. RF loading may be selectively applied to each parasitic element. When symmetric loading is applied to the parasitic elements, the parasitic array antenna may function as an omnidirectional antenna. When asymmetric loading is applied to the parasitic elements, a null and a directional beam may be formed for the parasitic array antenna, therefore providing beamforming capabilities to the parasitic array antenna.

摘要： A multi-band phased array antenna for radiating low frequency band signals and high frequency band signals. The multiband phased array antenna is formed from unit cells having waveguides for radiating high frequency band signals and end-fire radiating elements for radiating low frequency band signals. The unit cells have four walls with an open input end and an open radiating end. End-fire radiating elements are disposed on inner surfaces and outer surfaces of the four walls and radiate out the radiating end. Four waveguides are disposed together to radiate into the input end of the low frequency assembly.
