Abstract
We present a new waveguide slot configuration able to radiate a circular polarization with a very low axial ratio. Both LH and RH circular polarization can be independently obtained, and therefore this configuration can be used as a polarization agile antenna. The proposed antenna consists of two very closed radiating slots, so a specialized Method of Moments code have been developed to analyze the near field interaction between such slots.
