Abstract

This paper demonstrates a promising antenna solution for operation in harsh environment it consists of a metal-only transmitarray antenna. The latter is based on a C-shaped slot unit-cell exhibiting a phase variation of 360 degrees with insertion loss below 1-dB at 29 GHz. Various prototypes have been fabricated and then characterized in anechoic chamber to evaluate their performance. Here, two different antenna prototypes are presented demonstrating, respectively, beam pointing at 30 degree and 50 degree with good agreement between simulated and measured results. For beam pointing at boresight, the aperture efficiency is greater than 50% and the half power bandwidth is around 7.5% at 29 GHz. © 2020 EurAAP.
