Recently, 60 GHz band is considerably interested in wireless personal area network (WPAN) applications because sufficient bandwidth up to 7 GHz is available for Gigabit wireless link . The wideband applications of integrated millimeter wave circuits have created many challenges in frontend design. The 60 GHz front-end realized as an assembly of microwave monolithic integrated circuits (MMICs) in GaAs semiconductor technology . In this paper, the authors proposed a novel structure for a 61 GHz on-wafer horizontal directed antenna with a higher transmission gain than previous designs. The horizontal directed design usually obtains a narrower 3-dB beamwidth of radiation pattern than that of conventional dipole antennas. The measured and simulated results were demonstrated in the paper. A simplified model for the chip antenna was also described.
