A beam-forming antenna module is demonstrated using an integrated CMOS beam-former chip and a simple two-metal layer printed circuit board at V-band. The beam-former circuit integrates an absorptive single-pole four-throw switch together with a 4 × 4 Butler matrix using a 0.13-μm CMOS process. The entire insertion loss of the integrated beam former… CONTINUE READING
