| dc.description.abstract | 本論文提出兩種雙頻帶平面倒F天線之設計，分析與探討雙埠平面倒F天線系統的耦合現象，以及加入C形共振器設計以提高隔離度。首先，提出雙臂雙頻帶平面倒F天線與負載C形結構之雙頻帶平面倒F天線，藉由調整前者雙臂的長度和後者C形結構的長寬與位置，以改變天線之共振頻率及其頻率比例。接著，分析雙埠雙頻帶平面倒F天線系統擺放在近距離之下發生的耦合現象，阻抗匹配不佳與天線輻射效率降低等問題，並加入C形共振器當作去耦合架構改善上述問題，進而完成高隔離度雙頻帶多輸入多輸出平面倒F天線系統。最後，本論文亦提出平面倒F天線、雙埠平面倒F天線系統與單頻多輸入多輸出平面倒F天線系統之等效電路模型，與全波模擬軟體相互比較驗證，由其結果證明兩者相當吻合。 | zh_TW |
| dc.description.abstract | In this thesis, two types of dual-band planar inverted-F antenna (PIFA) are proposed. The coupling effects of the two-port antenna system are discussed and analyzed. The C-shaped resonator for enhanced port isolation of the MIMO antenna system is proposed, including the design, the prototype, and the modeling.
Firstly, the two-arm PIFA and PIFA loaded with C-shaped ring for dual band operation are proposed. By adjusting the two arms of the former antenna and the dimensions or the position of the C-shaped ring of the latter one, the desired operating frequency and the frequency ratio can be achieved. Secondly, the strong coupling and impedance matching issues are analyzed when the two PIFAs are closely spaced. By adding a C-shaped resonator as the decoupling structure, a dual-band MIMO antenna with high isolation can be achieved. Lastly, the equivalent circuit models of PIFA, dual-port PIFA system and single-band MIMO antennas are proposed and the results verified with HFSS full-wave simulation. | en |
