Abstract

In this paper, a phased array antenna based on thin-film dielectric technology at 60 GHz is designed. In order to reduce dividing/combining loss and avoid high loss of phase shifters, Rotman Lens has been employed as a feeder of antenna. The lens has 3 beam ports and 5 array ports with 2 dummy ports. The simulation for the design was performed by simulator using MoM(method of moments). The measured results of fabricated lens show magnitude deviation less than ${\pm}2dB$ and phase aberration less than ${\pm}5^{\circ}$ over $58{\sim}62GHz$. The antenna shows ${\pm}7^{\circ}$ of scan angles.
