| dc.description.abstract | 本篇論文設計了兩個多頻帶天線的架構，第一個天線是利用微帶線饋入方式所設計的四頻帶槽孔天線，第二個天線是利用共平面波導饋入方式所設計的五頻帶槽孔偶極天線。四頻帶槽孔天線是利用槽孔以及改變饋入微帶線的形狀，並且加入三段額外殘段之後，達到四個頻帶的效果。五頻帶槽孔偶極天線是利用在左右兩端的槽孔中各加入一塊金屬片，兩片金屬片上有四段不同長度的槽孔線，達到五個頻帶的效果。與電感式耦合饋入相比電容式耦合天線擁有較小的電路尺寸。兩個天線都是印刷式的天線，在電路的製作上較為容易。兩個天線的模擬與量測大致上都相符合，在每個通帶下所量測到的天線增益皆有3 dBi到5 dBi。 | zh_TW |
| dc.description.abstract | In this thesis, quad-band and penta-band antenna designs are proposed.
The quad-band antenna design is fed by microstrip line. The penta-band antenna design is fed by coplanar waveguide. The quad-band antenna design is achieved by adding three metal strips into slot and modified feeding line to generate four operating frequencies. The penta-band antenna design is achieved by adding a metal sheet which embedded four different length slot lines into each slot. The capacitively coupled CPW-fed antenna has more compact size than inductively coupled CPW-fed antenna. Simulation and measurement of two antennas show good agreement. The measured antenna gains are about 3 dBi to 5 dBi. | en_US |
