    Abstract: 本論文針對目前市面上單頻(GPS)倒F天線來做改良,改良成雙頻GPS倒F天線,而雙頻率包括GPS及Bluetooth。
     首先先由市面上所使用的單頻GPS倒F天線來做分析與討論,發現單頻GPS倒F天線中,經由電磁模擬軟體(HFSS)驗證後,可以得知反射係數、增益、輻射場型及天線的各種特性及其優劣。
     接著設計出雙頻(GPS/Bluetooth)倒F天線,不但可以利用共振頻率,使得原本只有單單一個GPS的頻帶外,另外再增加一個Bluetooth的頻帶,進而使得節省成本與縮小天線的面積。
    ;This thesis, A Dual-Band GPS/BT antenna for mobile phones is applied on the Planar Inverted-F antenna. The antenna makes the improvement. We change a GPS antenna on the Planar Inverted-F antenna. A Dual-Band GPS/BT antenna includes both GPS band bandwidth and Bluetooth band bandwidth.
     First, we design a GPS antenna. A lot of parameters that about the GPS antenna are found by the verification of the electromagnetic simulation software (HFSS). Then ,we can find S11、Gain and Radiation Patten from various kinds of parameter characteristics of the antenna to know the design is good or not.
     Finally, we design a Dual-Band GPS/BT antenna. We use multiple resonances frequency for GPS band bandwidth and Bluetooth band bandwidth. We can not only gain a GPS band bandwidth antenna, but also get Bluetooth band bandwidth antenna. We may achieve save the cost and the reduction antenna area goal.
