Abstract: Super-directive antenna arrays (SDAAs), conventionally designed to achieve exceptional directivity through mutual coupling, face an inherent drawback regarding their high impedance mismatch.
Abstract: In this paper, we present a 1.4 GHz on-chip correlation-Dicke hybrid radiometer designed for internal body thermometry. The GaAs Monolithic Microwave Integrated Circuit (MMIC) measures 3.8 ...
