Abstract In this study, a K‐band CMOS low‐noise amplifier (LNA) with a 180° phase shift function is presented to reduce the chip area of the beamforming system. The proposed LNA is composed of three stages, and the last stage is designed with a

Abstract A phase‐shifted circularly polarised ring microstrip antenna (PS‐CP‐RMSA), which can switch between three different phases, is proposed. The phase of a circularly polarised antenna can be shifted by changing the angle of rotation. Taki

Abstract A dual‐band vector‐sum phase shifter with independent phase control of the 2.4 and 5 GHz Wi‐Fi bands is presented. The network uses band‐limited variable gain amplification, with a broadband hybrid coupler at the input and an in‐ph
