Linear and circular polarization transmit-arrays at V-band
Résumé
This paper presents the design and demonstration of linearly-polarized and circularly-polarized transmit-arrays operating in the 60-GHz band. The arrays are fabricated with standard printed-board technology and are designed with a fairly simple structure using three metal layers. The experimental results show very good performances for both arrays with a gain of 22-23 dBi, a -3 dB gain-bandwidth of 11-13%, and low cross-polarization level.
