Abstract :
An integrated, circularly-polarized antenna comprising an annular slot and hybrid feed network fabricated on a standard liquid crystal polymer (LCP) substrate is described. The antenna is designed to operate in the WPAN band around 60 GHz. Modeled results for a single element and a 2x2 array are presented. The antenna bandwidth is sufficient to cover the entire WPAN band, and the array antenna has very low axial ratio, better than 0.3 dB across the band.
