Abstract :
An electronically-reconfigurable spiraphase-type element based on a ring slot resonator is analysed. It is demonstrated with numerical simulation and experimental measurements that optimal transformation of the switch impedances is possible in this element. As a result, low loss of 0.38 dB is obtained for the one-bit element at the frequency of 11.55 GHz.
