本篇論文主旨在於實現適用於超寬頻無線通訊系統之天線及濾波器。此篇論文中，天線及濾波器皆為平面式之架構設計。提出一個新型的共平面波導的超寬頻天線結合一個縮小化的帶通濾波器。提出的天線具有帶拒功能，是使用嵌入式諧振單元。
這帶拒天線在3.1到10.6 GHz滿足返回損失小於-10 dB，帶拒範圍在5.34到5.97 GHz。提出的濾波器是由開路步階阻抗殘段和開口諧振環缺陷地面結構組合而成。提出的寬頻帶拒天線加上寬頻濾波器的頻帶從3.1到10.6 GHz的電壓駐波比小於2.0，與拒帶範圍在5.13到5.97 GHz。單獨天線、濾波器及整合天線與濾波器均有量測結果，與模擬結果相當一致。

The purpose of this thesis is to design antennas and filters which can be used in UWB wireless communication system. In this thesis, planar antennas and filters are investigated and verified for UWB. A novel CPW ultra-wideband (UWB) antenna combined with a compact band-pass filter is proposed. The proposed antenna with band-notch function is to use embedded resonance cell.
The band-notch antenna satisfies the return loss requirement of less than -10 dB over the frequency range of 3.1 to 10.6 GHz with a rejection band around 5.34 to 5.97 GHz. The proposed UWB filter consists of two parts, a stepped impedance open stub and a split-ring resonator defected ground structure. The proposed band-notch UWB antenna with UWB filter has the frequency band of 3.1 to 10.6 GHz for VSWR less than 2.0 with a rejection band around 5.13 to 5.97 GHz. Measurement results are presented for antenna only, filter only and combined antenna and filter. The measured gain and insertion loss agreed well with simulation.
