Abstract :
The authors describe two variations of a novel aperture feeding technique for circularly polarized microstrip antennas. Measured results for a series-fed crossed-slot microstrip antenna are shown. Experimental results are shown that demonstrate an axial ratio bandwidth of 15% and an impedance bandwidth in excess of 20%.<>
