Zusammenfassung

Here, we propose a modulated geodesic lens antenna array in E-band (56-62GHz), which has scanning abilities in both azimuth and elevation. The array consists of four lens antenna elements, and each lens antenna produces 13 independent beams that cover 110 degrees in the H-plane with scan losses below 1dB. The array is fed with a 1:4 power divider comprising three phase shifters to scan in the E-plane. The distance between lenses in the E-plane is 0.7 wavelengths at 60GHz. The E-plane coverage is 60 degrees with scan losses around −2.2dB. The maximum realized gain varies from 20.8 to 24.1dB across the frequency band.
