Abstract:

A millimeter-wave (mm-wave) shaped transmitarray for wide-angle multi-beam radiations is proposed at 70.5 GHz in this paper. The transmitting surface shows a three-dimensional (3-D) elliptical cylindrical configuration. With desired maximal beam radiation angles, the elliptical curvature of the transmitarray and its phase compensations are jointly designed. A new focal arc is developed with different focal lengths for different radiation beams. Comparing to other reported works, it is demonstrated that the developed transmitarray can provide a wider beam coverage with a less gain drop at the maximal beam angle. Finally, the transmitarray prototype is fabricated and measured, achieving a continuous beam scanning between ±43° with a 2.7-dB scanning loss.
