Abstract:In this paper, a differentially-driven wideband multiple-feed on-chip antenna design in 0.13 µm SiGe technology is proposed for millimeter-wave power combining applications. The in-antenna power combining concept is achieved by combining parallel amplifiers in the multi-port radiator where each port corresponds directly to a differential power amplifier (PA) stage. Specifically, the radiator is composed of a leaky slot with multiple set of differential microstrip feed lines. A wideband Marchand balun with 1.5 … Show more
