碩士 === 國立交通大學 === 電信工程研究所 === 98 === In this thesis, a broadband high-gain cavity-backed antenna for 60 GHz Wireless Personal Area Network(WPAN) has been developed. Because the function of the cavity-backed structure is different from other antennas’, which is used to act as a shielding wall , it provides another resonant frequency to achieve wider bandwidth requirement. As a result, the proposed cavity-backed patch antenna remains high gain because of the utilization of cavity-backed structure. The 60GHz microwave transceiver system measurement has been done in the last chapter. To validate the circuit performance of each transmitter module and receiver module, we have measured conversion gain, bandwidth, P1dB, output power...etc. All of the measurement results have met with the 60GHz wideband and high transmission quality requirement. The broadband high-gain cavity-backed antenna and 60GHz microwave transceiver mentioned above have been verified with good identities which are capable of 60GHz wireless personal area network application.
