Abstract
A new compact CPW fed dual-band circularly polarized (CP) antenna for a broadcasting satellite application is presented. The proposed dual-band CP antenna consists of modified CPW ground structure by loading stub/slots/inverted L-strip and modified cross-shaped patch. A modified CPW ground structure can generate circular polarization (CP). The proposed antenna design provides the simulated impedance bandwidth (IBW) (S11 < -10 dB) of 81.42% (3.16-7.5 GHz) and 20.53% (11.8-14.5 GHz), respectively, and the 3-dB axial ratio BW (3-dB ARBW) for two bands are 29% (4.18-5.6 GHz) and 8.86% (11.86-12.96 GHz), respectively. The proposed CP antenna provides a maximum gain about 3.8 dBi and 5 dBi in lower and upper bands, respectively, with right hand circular polarization (RHCP) radiations. The overall size of the CP antenna is 27 × 27 × 1 mm3.
