초록
This paper presents a new reflectarray antenna capable with 1-bit switchable capability for W-band beamformingnetwork. The proposed antenna has been optimized using two unit-cells with sizes of 1.0 mm and 1.3 mm to forma total number of 193 radiating elements on a square aperture surface of length 30 mm. These radiating elementsare spaced 0.5 wavelengths apart and fed by a 15 dBi pyramidal horn antenna as the feed antenna placed 53 mmaway from the aperture center. The proposed reflectarray achieves a realized peak gain of 22.52 dBi, ahalf-power beamwidth of 5.1° in both E- and H-planes at the test frequency of 80 GHz and operates over a widebandwidth from 74 GHz to 90 GHz.
