Abstract

A novel design using diodes for tuning periodic phase shifting surfaces at millimetre-wave frequencies is proposed. The presented design consists of a unit cell simulation of a periodic surface with embedded diodes, placed over a ground plane. The tuning is achieved by means of an air-bridged Schottky diode; by varying the reverse bias, the impedance response of the metasurface can be altered, enabled by the variable junction capacitance. Simulations have been carried out using CST Microwave Studio to extract and evaluate reflection losses and the tuning range of the proposed phase shifter.
