ABSTRACT:
A sidelobe reduction benefit in a two-way pattern is accomplished when each attern (transmit or receive) has the same character as traditionally designed, but they differ in polarization. When polarization mismatch is included in the antenna pattern characteristic, the opposite sense of polarization in the sidelobe results in cancellation of signals between transmit and receive and, therefore, a net polarization loss or sidelobe level reduction in the combined two-way pattern. Polarization mismatch is accomplished by designing a separation distance between the transmitting elements and the corresponding receiving elements of the array. Choice of separation distance results in locating the region of perfect polarization mismatch in any desired angular direction.
