This paper presents a design process and simulation results of a 5 × 1 linear antenna array with phase shifters for 60 GHz beam steering applications. The antenna array has been designed using a membrane process in order to achieve high radiation efficiency and good radiation characteristics. The same process can be used to manufacture Micro-Electro-Mechanical Systems (MEMS) switches and phase shifters...
A 360deg phase shifter using a tunable quasi-lumped hybrid coupler was successfully designed. The phase shifter circuit delivers two evenly-split signals phase shifted over a 368deg controllable range. The phase shifter was connected to an antenna array made with two printed patches. The feasibility of pattern reconfiguration was validated by the Sij- and radiation pattern measurements.
This paper presents the design of a fully integrated antenna with directional diversity in the 60 GHz band using MEMS process on high resistivity silicon wafer. This active antenna designed for MIMO systems integrates switches and phase shifters.
