摘要

A millimeter-wave communication system needs a directive beam-steering antenna with a low scan loss to compensate the high free space loss. In this letter, an electronically beam-switching integrated lens antenna (ILA) system with low scan loss is designed for lower E-band (71-76 GHz). An ILA with hemispherical collimating surface of 26 mm radius and spherical feed surface of 37.5 mm radius is fab...
