This paper deals with the design of 2×2 Microstrip, Slotted rectangular waveguide antenna array and Patch-fed rod antennas needed for ultra high-speed, ultra high-capacity wireless communication systems which work at Millimeter waves at 60 GHz for different multimedia applications in indoor environments and illustrates its specifications and requirements. The antenna in such systems requires high gain, high-efficient, wider beamwidth and high performance design specifications. The designed antennas were simulated using electromagnetic software Agilent’s EMPro and Ansys HFSS. © 2012 IEEE.
