摘要
An annular-ring slot antenna with pair of slits and truncated corner for CP operation is proposed. A pair of slits and truncated corners are used to enhance axial ratio bandwidth. The proposed antenna is fabricated and simulated to analyze its radiation characteristics. Simulated results show a good agreement with experimental results. The antenna also shows much larger CP bandwidths than earlier reported results. The measured impedance bandwidth and 3-dB axial ratio bandwidth (ARBW) of the proposed antenna are 94.2 and 73.8%, respectively. The proposed antenna shows consistent return loss and radian pattern for entire frequency band.
