1,δ,1y and TE1,4,1y); (ii) modified feeding structure with parasitic strip generates CP wave in both the frequency bands; and (iii) The left-hand circular polarization (LHCP) and right-hand circular polarization (RHCP) of proposed antenna can be controlled by taking the mirror image of triangular ring-shaped aperture and parasitic strip. Simulated outcomes have been practically confirmed with the help of developed prototype of the proposed antenna. Measured and simulated results show high harmony to each other. The experimental results confirm that the proposed RDRA is operated over two frequency bands, i.e., 3.4-3.58 GHz and 5.1-5.9 GHz. The 3-dB axial ratio bandwidth of the proposed antenna is about 3.46-3.54 GHz (LHCP) and 5.18-5.34 GHz (RHCP) in lower and upper frequency band, respectively. The proposed antenna is fairly applicable for worldwide interoperability for microwave access and wireless local area network applications.">
