摘要：
The present study presents a novel microstrip line-feed compact square slot Circular-Polarization (CP) antenna for Ku-band applications. The proposed square slot antenna with circular trimmed corners was fabricated with the FR-4 substrate with the defected ground on the opposite side of the patch. The Axial Ratio Band-Width (ARBW) was considerably enhanced by adding a shorting pin and the Impedance Band-Width (IBW) was improved by etching the pentagon-shape slot in the defected ground. The antenna offered the wide CP IBW of 4.96 GHz (13.6 GHz{18.56 GHz), simulated ARBW of 4.85 GHz (14.51{19.30 GHz), and positive gain in the Ku-band. The presented antenna is appropriate for Ku-band applications.
