Advanced Pinwheel Compact Controlled Reception Pattern Antenna (AP-CRPA) designed for Interference and Multipath Mitigation

Waldemar Kunysz

Abstract:	This paper describes the design of a compact, dual GPS frequency L1/L2, multi element adaptive antenna array, where each array element is comprised of an aperture coupled spiral slot array. In short, it is an array of arrays. The design of a seven element array is described. The design is quite different from existing CRPA antennas which use a stacked patch approach. The aperture coupled spiral slot array methodology allows a reduction of mutual coupling between the adjacent elements of the array, and hence a reduction of the overall size of the antenna. In addition, its wide band performance will allow it to meet future GPS M-code requirements. The array has a low profile with a maximum height of 0.8”.
