60 GHz寬頻高增益背腔式天線與收發機系統量測

Abstract

本論文設計一隻可應用於60 GHz高速傳輸收發機天線，透過微帶天線激發出在共振頻率在60GHz的背腔式共振腔模態，不僅能達到頻寬上的需求，並且對於微帶天線本體的輻射也能提升增益，其參數的分析與探討於內文中。 另外在60GHz毫米波收發機電路作系統驗證，分別針對接收端模組及發射端模組量測電路特性，驗證結果皆達成寬頻的要求。 上述寬頻高增益天線以及60GHz收發機電路，都已實際驗證出良好特性，可應用於60GHz 無線個人區域網路。

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.
