Dual Band CP Antenna with Stub and Inverted L-Strip Loaded for Broadcasting Satellite Applications
A dual-band characteristic of the circular polarized (CP) antenna with stub and inverted L-strip loaded for a broadcasting satellite application is presented. The dual-band CP antenna has a modified ground structure and stair shaped patch. A modified CPW ground structure can generate CP. The proposed design provides the dual-band that has impedance bandwidth (IBW) ranging from 81.42% (3.16–7.5GHz) and 20.53% (11.8–14.5GHz), respectively, and the 3-dB ARBW (Axial Ratio Bandwidth) for two bands are 29% (4.18–5.6 GHz) and 8.86% (11.86–12.96 GHz), respectively. The proposed CP antenna is providing a maximum gain of about 3.8 dBi and 5 dBi in dual bands, respectively, with good Right Hand Circular Polarization (RHCP) radiations. The overall size of the CP antenna is $27\times 27\times 1\ \text{mm}^{3}$.
