Abstract :
This paper presents the design of a monolithic phased array antenna with DMTL phase shifters on quartz substrate operating at 35 GHz. The design integrates DMTL phase shifters, rectangular slot antennas with the feed network comprising CPW lines, CPW T-junction and corners. On the four branches of the antenna, there are 5-bit phase shifters using 31 MEMS bridges, covering 360° with a resolution of 11.25°.
