Abstract :
A novel method to realized circularly polarized (CP) antenna has been investigated, based on substrate integrated waveguide (SIW) cross-slot. Compared with the conventional antenna the single unite has excellent axial ratio (AR). What´s more, the feed port of this antenna is very simple. When it is composed of array, the gain and the depth of its resonance can be improved.
