A dual band dual polarized planar slot antenna using coplanar waveguide feed (CPW) is presented in this letter. The proposed antenna consists of a pentagonal shaped ground and a stair shaped radiating patch directly connected to feed. Pentagonal slot is perturbed by a rectangular stub embedded in the ground and ground is modified by etching a rectangular slot in the ground. The proposed antenna exhibits dual band characteristics with lower band linearly polarized and upper band circular polarized. Asymmetric excitation resulting due to stair shaped patch results in excitation of circular polarized radiations for the upper band while the lower band remains linearly polarized. The linear polarized lower band extends from 1.98GHz-3.78GHz while overlapping upper band i.e. VSWR less than 2 dB and Axial ratio less than 3dB exists from 4.6GHz-5.9GHz,thereby proposed antenna covering Bluetooth and WLAN usable bands by dual resonating bands.read more

CPW-Fed Broadband Circularly Polarized Planar Monopole Antenna With Improved Ground-Plane Structure
TL;DR: In this article, a planar printed monopole antenna with broadband circular polarization (CPW) characteristic is presented, which consists of a rectangle patch and an improved groundplane, and the measured results show that the proposed antenna has not only a broad 3-dB AR bandwidth of 44.9% (2.65 GHz, 4.58-7.23 GHz) with respect to the CP center frequency 5.90 GHz, but also a wide 10-dB return loss bandwidth of 76.9%.
