TLDR
In this article, a dual-band planar slot antenna with asymmetric patch and modified ground is proposed for ISM band applications, which provides circular polarization for two frequency bands which extends from 3.3GHz-3.7GHz and 5.18GHz-5.40GHz.Abstract:
A dual band circular polarized antenna using CPW feed is presented in this paper. The proposed antenna is a dual band planar slot antenna having an asymmetric patch and modified ground. Both resonating bands are circular polarized with axial ratio < 3dB.Circular polarization is achieved in the proposed antenna by introducing an inverted L shaped grounded strip in the proposed structure. The antenna provides circular polarization for two frequency bands which extends from 3.3GHz-3.7GHz and 5.18GHz-5.40GHz and can be used for ISM band applications.read more

Co-Planar Waveguide Fed Dual Band Circular Polarized Slot Antenna
TL;DR: In this paper, a coplanar waveguide (CPW) fed dual band circular polarized (CP) slot antenna is proposed, where a modified asymmetric stub loaded feedline is used along with a square shaped slot in the ground plane to achieve two broad impedance bandwidths (|S 11 |< −10 dB).
