摘要：

This paper presents a highly isolated phased array antenna system for SG applications at 28 GHz. The antenna array is formed by 1x8 microstrip antipodal exponential tapered slot antennas each connected to CMOS phase shifters with wire bonds for electrical beam steering. At 28 GHz, the mutual coupling between the antenna elements are lower than -30 dB while the envelope correlation between the ports is less than 0.1. The single antenna array element was fabricated on 20 mil thick Rogers 4003 substrate and the phase shifter was fabricated in 22 nm FD-SOI CMOS. The simulated and measured results of the single antenna element along with the integrated phase shifter are presented together with the simulation results of the overall system.
