Abstract

In this letter, a new configuration of reflectarray antenna element is proposed. A frequency-reconfigurable element for beam-scanning reflectarray is introduced. The reconfigurable reflectarray antenna element requires two PIN diodes and one varactor to provide a reflection coefficient with continuously tunable phase over a 270 degree range which can be shifted over a 50% frequency range. Microstrip spoof surface plasmon polarition (SPP) is introduced on the side of the patch. Through this method, the reflection phase shift range of reconfigurable reflection array element increases by dozens of degrees.
