A 1-bit 14 × 14 Dual-beam Electronically Reconfigurable Reflectarray

Abstract

An element is proposed in this paper which is composed of two trapezoidal patches and one PIN diode. The 180° phase difference can be achieved by tuning the working states of PIN diode. Utilizing the proposed element, a dual beam reconfigurable reflectarray antenna (RRA) is designed. The RRA is simulated in Ansys HFSS 15 and the full-wave simulations show a good beam-scanning of the reflectarray antenna. Symmetrical and asymmetrical, equal and unequal amplitude dual beams scanning can be obtained by changing the reflection phase.
