碩士 === 國立臺灣大學 === 電信工程學研究所 === 105 === This paper presents the design of a subarray module for the implementation of phased array of antennas at millimeter wave frequency band. In particular, two antenna ports are created to provide the possibility of implementing self-sufficient independent beamforming networks for the transmitting and receiving systems by embedding a circulator. The radiation pattern of the module is properly designed to avoid the appearance of grating lobes in the formation of phased array of antennas.The radiation characteristics of both the subarray module and the phased array of antennas are examined by numerical simulation and experimental measurement over the antenna prototypes.
