E-Band Low-Loss Reconfigurable Phase Shifters [PDF]

, 2023
Two types of low-loss mechanically reconfigurable phase shifters at E-band based on gap waveguide (GW) technology, the GW slow wave and the GW width-variation, are proposed in this letter. Phase shifts are achieved by mechanical movements.
