碩士 === 正修科技大學 === 電子工程研究所 === 98 === In the thesis, the PIFA including shorting structure which can meet the application specification of BT, WLAN, WiMAX in a metal cover of laptop computer has been proposed. In the Chapter 2, of the PIFA structure application on BT, the Antenna positioned in no RF window space in BT application can improve the performance by shorting the Antenna to system ground plane. In the chapter 3, the radiation structure using a PIFA and two shorting strip can generate dual band resonant mode to cover WLAN frequency band. In the chapter 4, because the WiMAX band include the WLAN band, changing the direction of the shorting strip in PIFA structure in chapter 3 can generate wider bandwidth to cover the WiMAX application band. Above of all three antenna structure, the use of the shorting structure can reduce the influence of metal top cover.
