Abstract

A novel design of a dual band metasurface unit element using two diodes for independent phase shifting in two frequency bands with low reflection losses is presented. Control of the capacitance and thus of the reflected phase can be achieved by independently applying a reverse bias to the two air-bridged Schottky diodes that are embedded on the phase-shifting element. Simulations of the proposed design are presented and the currents and losses are studied. CST Microwave Studio was used to evaluate the tuning range and reflection characteristics of the proposed design.
