Low-profile high efficiency transmitarray antenna using optimized phase compensation surface (PCS) and PEC sidewalls

A low-profile high efficiency transmitarray antenna (TA) using an optimized phase compensation surface (PCS) and PEC sidewalls is proposed in this paper. Generally, TAs are composed of a source antenna and a planar PCS, and the PCS makes the phase of transmitted wave through the PCS be in-phase, res...
