Abstract

Presents a novel dual polarised slotted waveguide array antenna. It is intended for an advance synthetic aperture radar with polarimetric capabilities. Special emphasis is given to achieve a compact subarray design with large bandwidth, high polarisation purity, low loss and high port to port isolation. A breadboard antenna example is presented at 9.6 GHz having a scan range of ±23° transverse the subarray axis
