在本論文前段中，我們提出寬頻多邊型槽孔天線與介質共振天線的設計。在多邊形槽孔天線設計中，在寬槽孔旁加上一小槽孔來激發另一共振模態以形成寬頻操作，使之適用於PCS、IMT-2000、藍芽、802.11a/b/g的應用頻段內，並在槽孔內植入微擾金屬片來改善天線輻射場型特性。在介質共振天線設計中，利用寬槽孔來增加耦合，並且在饋入線中以一魚叉狀饋入形成兩條不同電流路徑來激發出兩個共振模態，使天線頻寬有效增加，且因介質共振天線是以高介電係數之陶瓷材料為輻射體，可以達到天線尺寸縮小化的優點。最後則是提出一天線與濾波器整合之模組，可以有效濾掉系統頻帶外的雜訊降低雜訊振數，並且大幅縮小前端模組面積。

　　In this thesis, wideband polygonal slot antenna and dielectric resonator antenna have been proposed. First part, the design of the polygonal slot antenna for the wideband operation, a small slot is placed on the feed side of wide slot. Experimental results shows that the polygonal slot antenna bandwidth cover most commercial wireless communication, including PCS, IMT-2000 Bluetooth, 802.11a/b/g. Except for the reduce cross polarization, we present the four tuning patch to improve cross-polarization level of antenna radiation pattern.
　　Second part, a compact wide aperture-coupled broadband cylindrical dielectric resonator antenna has been proposed. For improving impedance matching, microstrip feed-line was designed as a fork-like to obtain two resonant modes excitation and lead to a wider impedance bandwidth.
　　Finally, we present an integration of filter and antenna module. This antenna module filters out the out-of-band signals, so that noise figure and size of RF front-end can be reduced.
