A study and comparison of high frequency materials more suitable than Silicon for antennas for MMIC

A comparative study of Gallium Arsenide (GaAs), a semiconductor materials more suitable than Silicon for high frequency circuits has been presented in this paper. A Yagi-Uda antenna, intended to work on millimeter wave integrated circuit is designed using both silicon and Gallium-Arsenide (GaAs) and the results have been compared. The designed antenna is suitable for on-chip application on millimeter wave. Antenna design and simulation has been done on HFSS FEM simulator.
