T. Dutta . Compact-Sized Ultra Wideband Circularly Polarized Microstrip Patch Antenna. CAE Proceedings on International Conference on Computing. CCSN2015, 1 (March 2016), 0-0.
A compact-sized single-fed circularly polarized single-layered microstrip patch antenna at X-band is proposed. The antenna is a modified form of the previously developed E-shaped rectangular patch with two parallel unequal slots. For improving the impedance matching performance,the circular reformations are introduced on each of the slot's end. The circles make the fields on the slots uniform without any tangible effect on the axial ratio. The antenna is designed on a thin ROGERS RT/DUROID 5880(tm) substrate with dielectric constant (?r) of 2. 2 and thickness of 1. 6mm. At the operating frequency of 10GHz, the overall size of the antenna is 15. 43mm x 8. 21mm x 1. 6mm. The simulated result shows that the antenna achieved an ultra wideband impedance bandwidth(S11<-10dB) ranges from 9. 16GHz to 10. 25GHz.
