E-Band Low-Loss Reconfigurable Phase Shifters
Journal article, 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. To avoid wave leakage and undesired resonances during the movement, quasi-PEC-AMC structures are implemented. The phase shifters have been fabricated and measured. The results show that the insertion losses are about 0.4 and 0.3 dB, and the reflection coefficients are better than $-$ 13 and $-$ 15 dB for the slow wave and the width variation, respectively, over 71-86 GHz.
