Non-volatile Pattern Reconfigurable Antenna Based on Even- and Odd-Mode Spoof Surface Plasmon Polaritons

In this paper, a novel non-volatile radiation pattern reconfigurable spoof surface plasmon polaritons (SSPPs) antenna is proposed. The antenna can radiate between even- and odd-mode to radiate broadside and endfire beams respectively. Due to the feature of non-volatile switches, no static power is needed to maintain the antenna operation states, significantly reducing the DC power consumption. Such nonvolatile reconfigurable antennas will be highly desirable, especially for low power sensing systems and large antenna arrays where hundreds even thousands switches.
