此論文首先以單極天線的形式來設計沒有抑制頻段的超寬頻(UWB)天線。天線的外觀類似漏斗的形狀,是使用三角形和矩形的貼片組合而成,並在天線背面的接地面挖矩形槽,用來提高天線的頻寬。當設計的天線的反射係數達到比3.1~10.6GHz更寬的頻寬之後,再把用以當抑制WLAN(5.5GHz)頻段的互補開口環形共振結構(Complementary Split-Ring Resonators,CSRR)加在天線背面,接地面上方以貼片組成,並且增加天線的緊湊性。
本論文之超寬頻天線設計在長寬高為33.05mm*26.4mm*1.6mm的FR-4的基板上。天線的操作頻段為3.1至10.6GHz,設計的抑制頻段為5.29至5.84GHz,包含5.5GHz的WLAN頻段。

This paper first designed an ultra-wideband (UWB) antenna with no suppression band in the form of a monopole antenna. The appearance of the antenna is similar to the shape of a funnel. It is formed by combining triangular and rectangular patches, and a rectangular slot is dug on the ground plane on the back of the antenna to increase the bandwidth of the antenna. When the reflection coefficient of the designed antenna reaches a bandwidth wider than 3.1~10.6GHz, the complementary split-ring resonance structure (CSRR) used to suppress the WLAN (5.5GHz) frequency band is added to on the back of the antenna, above the ground plane is composed of patches, and increases the compactness of the antenna.
The ultra-wideband antenna in this paper is designed on an FR-4 substrate with a length, width, and height of 33.05mm*26.4mm*1.6mm. The operating frequency band of the antenna is 3.1 to 10.6GHz, and the designed suppression frequency band is 5.29 to 5.84GHz, including the 5.5 GHz WLAN frequency band.
