Abstract :
This paper presents a study on a novel reconfigurable orthogonally-polarized dual band high-gain Resonant Cavity Antenna (RCA). The RCA includes a Partially Reflective Surface (PRS) of printed slotted-patches with switch array across the slot which is designed based on the novel concept of half-phase-gradient PRS. The upper band has a broadside beam with V-polarization. The lower band is able to scan broadside and also 10-32° off broadside, depending on frequency and switch configuration with H-polarization.
