本論文探討兩款新型天線設計。第一款天線為四臂多頻平面單極手機天線,可應用於GSM900、DCS 1800、PCS1900、IMT2000、WLAN 802.11 a/b/g等多個頻段。本篇論文之第二款天線係利用多層RO4003基板,設計具帶拒特性之超寬頻單極天線,該天線設計於3.1GHz到10.6 GHz的超寬頻頻帶,並於5~6 GHz間具有帶拒效果,俾利使系統不受WLAN訊號之干擾。
This thesis investigates two new antenna designs. The first antenna is a four-arm planar monopole for mobile phone applications. The antenna covers the frequency bands including GSM900, DCS1800, PCS1900, IMT2000, and WLAN 802.11 a/b/g.The second antenna design is a multilayered ultrawideband antenna with band-notched characteristics. The antenna is designed for ultrawideband applications from 3.1 to 10.6 GHz with a rejection band at 5 to 6 GHz. The notched band is capable of alleviating the interference from the WLAN signals.
