IEEE802.11a/b/g為常用的無線網路協定,對室外的點對點技術而言,高指向性的天線能增加傳輸距離及提升傳輸速率,而一般常以陣列的方式提高指向性。

本論文將以Patch天線設計應用於IEEE802.11a/b/g的Access point (AP),Patch天線有較易設計陣列的優點。對陣列天線而言,阻抗匹配是相當重要的一環,以2、4及8個陣列做阻抗匹配的研究,以提高天線的指向性。

除此之外,為了配合Multiple-Input Multiple-Output (MIMO)系統,雙極化功能也加入天線陣列中。本論文中皆以GEMS電磁應用模擬軟體對陣列天線做分析及研究。

IEEE802.11a/b/g is the wireless network protocol. For point to point outdoor Wi-Fi communication, highly directional antennas can increase the transmission distance and throughput, the common way is design antenna array to increase the antenna gain.

In this thesis, the access point of wireless network designed by patch antenna, patch antenna is easier to design array structure. For patch antenna, the impedance matching is important, and analysis impedance matching of 2, 4, 8 elements antenna array to increase antenna directivity.

In addition, in order to use for MIMO system application, therefore designed the dual polarization antenna array. In this thesis, the antenna arrays of design and analysis by GEMS EM simulation system.
