在本篇論文中，提出了兩種不同極化的天線，分別為線性與雙極化天線的設計，並且針對所提出的天線特性去做分析與探討，其一是以矩形微帶天線為基礎，設計出陣列的形式。另外一支天線為應用槽孔天線，變化為雙饋入的雙極化天線。本論文之天線，是為了能應用於IEEE802.16所設計出來的天線，而其操作的頻帶為3.4~3.6GHz，此頻帶用於歐洲、亞太等地區，且使用HFSS(High Frequency Structure Simulator)軟體，來分析天線架構，模擬與實作皆有很好的一致性。

In this paper, We will propose two kinds polarization antennas, For being linear and dual polarization antennas designs,and analyse the characteristic of the antenna, The basic structure of the one of the microstrip patch antenna, design the form of the array. Another antenna is a slot antenna, change slot antenna for dual polarization antenna. All these antennas are designed for and IEEE802.16 applications. antennas with frequency between 3.4 and 3.6 GHZ,The band can apply to Asian-Pacific and Europe.Here we use HFSS (High Frequency Structure Simulation) to analysis the structure of the antennas. Good agreement is obtained between simulation and experimental results.
