Abstract

In this letter, a planar monopole UWB antenna with dual band-notched characteristics is proposed. The band-stop characteristics is realized by embedding the 1st/3rd order Hilbert-curve slots on the patch. With the dimension adjustment of each Hilbert-curve slots, the band rejection from 3.3 to 3.7 GHz and from 5.3 to 6 GHz can be accomplished easily. The VSWR and radiation pattern of the fabricated antenna are measured, and the proposed antenna would be adequate to a UWB applications.

본 논문에서는 이중 대역 저지 기능을 갖는 평판형 모노폴 UWB 안테나를 제안하였다. 제안된 안테나의 대역 저지 특성은 패치 상의 1차와 3차의 힐버트 곡선 슬롯들에 의하여 구현되었다. 각 힐버트 곡선 슬롯의 크기를 조절함으로써, 3.3에서 3.7 GHz 그리고 5.3에서 6 GHz에 걸친 저지 대역을 쉽게 구현할 수 있었다. 제작된 안테나의 VSWR과 방사 패턴을 측정하였으며, 이 결과로부터 설계된 안테나가 UWB 통신에서 사용될 수 있음을 알 수 있었다.
