Abstract :
The authors propose a novel CP (circularly polarized) generation method for slot-coupled microstrip antennas using a parasitically excited slot in addition to a directly excited slot. Experimental results and numerical analysis using the spatial network method are described. Experimental results have indicated that good CP performance has been obtained.<>
