WiMAX的廣泛應用與不斷推出的終端產品吸引了大多數人的注意，並且在2008年Taipei Computex被選定為主要的展覽主題，發展的趨勢與應用的需求明顯地指出這是一個即將不斷地成長的市場，此乃為研究的初始動機。
本篇論文主要目標在於詳細介紹三個新型的天線，內容中提供了充分的數據與結果，分別依照軟體模擬與實作量測當中去做分析與比較，內文並詳盡地介紹設計天線的相關原理，並討論使用一些基本的方法讓天線在被放入模擬軟體與實際製作之前就可以估計出天線的初步工作頻帶與效能，與整個細微調整天線的過程。
論文的天線已經完成實作，並且在經過良好校正過的無反射實驗室當中量測，基本要素如天線的反射損失 Return Loss < -10dB 在所有工作頻帶都需符合。天線的電壓駐波比 VSWR < 2 的要求，在所有工作頻帶都需符合。並擁有全方向性的輻射場型的特性。

論文中的天線已經完成模擬與實作，並於詳細的量測中確認可以應用於下列頻帶當中：
 1740 ~ 1785MHz (傳送頻帶) 以及 1805 ~ 1880MHz (接收頻帶)應用於DCS1800 頻段的產品.
 1850 ~ 1910MHz (傳送頻帶) 以及 1930 ~ 1990MHz (接收頻帶) 應用於 PCS 與 WCDMA 1900頻段的產品.
 1920 ~ 1980MHz (傳送頻帶) 以及 2110 ~ 2170MHz (接收頻帶) 應用於WCDMA 2100頻段的產品.
 2412 ~ 2484，5150 ~ 5350，以及5725 ~ 5825MHz應用於全世界 Wi-Fi頻段的產品。
 2500 ~ 2690, 3400 ~ 3690 以及 5250 ~ 5850MHz 應用於全世界 WiMAX頻段的產品。

The object of thesis is purposed to provide all completed processes on designing planar antennas applying to UMTS, Wi-Fi and WiMAX frequency bands, theories of electromagnetism are demonstrated to estimate antenna size and performance in early stage. Procedures of implementing three types of actual antennas have been detailed illustrated in following chapters.
The motivation was come from that WiMAX was designated as one of topical subject on Computex 2008 in Taipei World Trade center, the tendency from coming topics and products obviously indicate this market is rapidly growing up and expanding; the research is intended to have a perspective investigation included UMTS, WiFi and WiMAX technology, and discuss topical requirements of Antenna.
All the measurements have been performed in well calibrated anechoic chamber, in the next chapter 5, the summarized results documented all the design process and demonstrated essential performance data on proposed antenna had met expected targets with following condition:
 Antennas’ Return loss < -10dB in required working frequency bands.
 Antennas’ VSWR < 2 in required working frequency bands.
 Antenna should have Omni-Directional radiation characteristics.
The proposed antenna had been made and checked it could meet following frequency bands.
 1740 ~ 1785 MHz (uplink) and 1805 ~ 1880 MHz (downlink) for DCS1800 applications.
 1850 ~ 1910MHz (uplink), 1930 ~ 1990MHz (downlink) for PCS and WCDMA 1900 applications.
 1920 ~ 1980MHz (uplink), 2110 ~ 2170MHz (downlink) for WCDMA 2100 applications.
 2412 ~ 2484, 5150 ~ 5350, and 5725 ~ 5825MHz for worldwide Wi-Fi applications.
 2500 ~ 2690, 3400 ~ 3690 and 5250 ~ 5850MHz for worldwide WiMAX applications.
