A Novel Wide-Band Circularly Polarized Patch Antenna Based on L-Probe and Aperture-Coupling Techniques

Research output: Journal Publications and ReviewsRGC 21 - Publication in refereed journalpeer-review

Abstract

The design and measurements of a wide-band patch antenna with circular polarization are presented. For the proposed antenna, an L-probe and an aperture are utilized to feed the patch orthogonally. The distance between the patch and the ground plane is 0.1 free-space wavelength at 1.8 Ghz. Air is used as the dielectric substrate. A Wilkinson power combiner is connected to the feeds to generate circular polarization. The antenna possessed a 14-Db return loss bandwidth of 35% (from 1.49 to 2.12 Ghz), and has a 3-Db axial ratio bandwidth of 20.4% (from 1.67 to 2.05 Ghz). The 3-Db axial ratio beamwidth and the boresight axial ratio are 84° and 1.94 Db at 1.8 Ghz, respectively.
