Abstract :
A novel design is described for a dual-band circularly polarized pentagonal slot antenna. The circular polarization (CP) radiation characteristics are achieved by loading with proper asymmetry, which is placed at the opposite angle of the feed line. A prototype of the proposed design is implemented and measured. Measured results show that radiation patterns with good CP characteristics are obtained at the two resonant frequencies.
