• Type1天線使用Monopole的方式製作， FR4底板 1.6mm，介電系數 4.4• Type2天線使用 PIFA的方式製作， FR4底板 1.6mm，介電系數 4.4
Type1天線的頻帶與 S11模擬和實測GSM(880 960 MHz),DCS (1710 1880 MHz)PCS (1850 1990MHz)UMTS (1920 2170 MHz)WiBro (2300 2390 MHz)ISM (2400 2483 MHz)and also covers GNSS, includingCOMPASS (1559.052 1591.788 MHz)GPS (1575.42 5 MHz)GLONASS (1602 1615.5 MHz)
Type2天線的頻帶與 S11模擬和實測1163.72~1605.8865 MHz
Type1:Circular polarization(CP)利用兩個天線環繞的方式造成角度的呈現 90度的變化達到圓極化的功能判斷是依據軸比 (AR)是否 <3dB
Type2:Circular polarization(CP)使用 PIFA對稱的結構，造成圓極化的效用判斷是依據軸比 (AR)是否 <3dB
心得 :其實對於天線沒有懂得很透徹，畢竟大學時候專題不是做這塊，可是慢慢做之後，越來越有興趣，但現在單純設計天線可能已經飽和了，所以目前想法是做系統整合，看能不能將設計的 READER和 TAG這樣搭配再寫個軟體介面進行結合，只是不曉得能不能行，可能還是要多多看一些論文，多做比較。
