Integrated microstrip-fed slot array antenna for emerging wireless application in IPD technology

In this paper, the design of a 2-by-1 array of microstrip -coupled slot antenna in Integrated Passive Device (IPD) technology is explained. This antenna which operates in the frequency range 57-64 GHz, has maximum gain 4.9 dBi. The radiation efficiency at 60 GHz is 76%. The designed antenna is integrated over an alumina substrate using flip-chip bonding technique. The size of the antenna is 2 mm × 4.5 mm and can be used for antenna in package for mm-wave wireless systems.
