A 1-bit, Low-Complexity, 20×20-Element Electronically Reconfigurable Reflectarray Antenna

This paper presents an electronically reconfigurable reflectarray antenna with 1-bit phase correction. A low-complexity phase-shifting element with four patches and only one PIN diode is proposed to provide two electronically switchable states with a 180° phase difference. The reconfigurable reflectarray having a 300 × 300-mm2 aperture and a feed horn antenna were modeled and simulated in ANSYS HFSS. Full-wave simulated results show a good beam scanning performance from 8.7 GHz to 10.1 GHz over the scan range of ±45°. The simulated maximum gain and aperture efficiency are 23.5 dBi and 18%, respectively, at 10.1 GHz.
