This letter presents a new linearly polarized phase-shifting cell for reflectarray applications. It consists of three parallel rectangular slots etched in a ground plane and loaded with a combination of variable and fixed capacitances to provide a 2-bit phase-shifter. The proposed cell is fabricated and characterized in C-band using the waveguide simulation(More)
A new dual linearly polarized phase-shifting cell for reflectarray applications is presented. It consists of two orthogonal sets of parallel rectangular slots etched in a ground plane. Each set may be loaded with a combination of variable and fixed capacitances to provide a reconfigurable 2-bit phase-shifter for both polarizations. A passive version of the(More)
— This paper presents a new phase-shifting cell topology for reflectarray. It consists of a symmetrical set of three parallel rectangular slots loaded with a combination of variable and fixed capacitances to provide four uniformly-distributed phase states with a large bandwidth. Two different slot lengths are combined to improve the bandwidth. The cell is(More)
