Aperture coupled dual band dual circularly polarized stacked microstrip antenna

The dual band, cross CP design (namely LHCP and RHCP) presented in the paper is based on simulation results. The design involves some typical sensitive parameters such as thickness of substrate materials, unequal cross-slots lengths and orientation. The two well separated frequency bands of the proposed dual band antenna may be suitable for simultaneous transmission and reception applications. The reason for selecting the design parameters have been discussed.
