Abstract :
The communication presents a novel microstrip line-fed compact square slot circular polarized antenna for Ku-band applications. The proposed square slot antenna with circular trimmed corners is fabricated on the FR-4 substrate with the defected ground on the opposite side of the patch. The axial ratio bandwidth (ARBW) is considerably enhanced by adding a shorting pin and the impedance bandwidth (IBW) is improved by etching pentagon- shaped slot in the defected ground. The antenna offers wide CP impedance bandwidth of 4.96GHz (13.6GHz-18.56GHz)) and simulated ARBW 4.85GHz (14.51-19.30GHz) and positive gain in the Ku-band. The presented antenna is appropriate for Ku-band applications.
