Abstract

The design of a novel electro-mechanically tunable reflection phase-shifting metasurface at millimetre-wave frequencies is presented. In this paper, an unconventional phase-shifting approach with a variable air cavity between a periodic surface and a ground plane is presented, that provides enhanced reflection phase-shifting bandwidth in both TE and TM polarizations. Simulations have been carried out using CST Microwave Studio to evaluate the reflection response and the tunability of the proposed metasurface. Simulations demonstrate a continuous 180° phase shift with an operating frequency band from 45 GHz to 65 GHz with extremely low reflection losses.
