WiMAX(Worldwide Interoperability for Microwave Access，全球互通微波存取)主要應用於手持式行動裝置，例如筆記型電腦、手機或PDA；筆記型電腦要求輕薄與小尺寸，因而影響到各元件的大小，本論文在於研究印刷式平面型的倒F天線，內建於筆記型電腦內，在有限的空間下，使用易於製造的FR4版製作應用於WiMAX的天線，以全波模擬軟體IE3D或HFSS設計，頻率範圍包括2.3GHz~2.8GHz，3.3GHz~3.8GHz，4.8GHz~5.8GHz，使用頻帶甚至可包含WLAN及藍芽的使用頻率。

WiMAX(Worldwide Interoperability for Microwave Access) apply to Hand-held Devices, such as notebook , mobile phone and PDA .The notebook request of more lighter, more thinner and more smaller, and therefore affect the component size. This thesis focuses to designs printed Planar Inverted F Antenna (PIFA) in notebook. In finite space , We use printed circuit broad (PCB) to production this antenna for WiMAX Applications . We also design and simulated with a full wave EM software (HFSS or Ie3D), the band is 2.3GHz~2.7GHz and 3.3GHz~3.8GHz and 4.8GHz~5.8GHz. The band work in WLAN or Bluetooth
