Abstract

A dual-band orthogonally and circularly polarized antenna array with disparate elements is presented. By using corner-truncated stacked patches as elements, both left hand circular polarization (LHCP) in 12 GHz band and right hand circular polarization (RHCP) in 14 GHz band are realized in a shared antenna aperture. Furthermore, by employing disparate elements, the coupling between the two bands is suppressed effectively inside the feed network, hence improving isolation. The measured results of a four-element array agreed well with the simulated ones, achieving isolation better than 20 dB in the dual bands, and a maximum gain of 13.2 dBic for the LHCP and 13.9 dBic for the RHCP. The proposed array can find applications in satellite communications.
