A wideband circularly polarized L-shaped monopole slot antenna has a single C- shaped feed. The measured results demonstrate that the antenna has 23% of circular polarization bandwidth (Axial Ratio < 3 dB and Return Loss <-10 dB). The monopole slot antenna occupies a half area on the corner of circuit board compared to half-wavelength slot antenna that requires the area at the center of the board. This feature is attractive for compact wireless devices operate at low frequencies in which circuit board floor planning and signal routing are major concerns. The antenna is extremely low cost and does not require any truncation corner, reflector surface and via connection which increase the fabrication cost.
