Abstract

In this paper, we present a compact planar dual band rejection Ultra Wide Band(UWB) antenna with folded parasitic element. The proposed antenna is consist of a hexagonal planar radiation patch antenna with a folded parasitic element which is located over the top and bottom surface. In contrast with other antenna which rejects single band using one method, folded parasitic element rejects dual band using one simple structure. Owing to folded parasitic element, dual-rejected properties are achieved in the Worldwide Interoperability for Microwave Access(WiMAX), C-band, and Wireless Local Area Network(WLAN) bands. The bandwidth of the proposed antenna was measured as 3.1~10.6 GHz for voltage standing wave ratio(VSWR) less than 2, except for the dual rejection bands of 3.4~4.2 GHz and 5.15~6.00 GHz.

본 논문에서, 접힌구조의 기생소자를 갖는 이중대역을 저지하는 대역저지 UWB 안테나를 구현하였다. 제안된 안테나는 정육각형 평면 방사 패치를 갖는 안테나에 안테나의 윗면과 아랫면에 걸쳐 있는 접힌구조의 기생소자로 구성되어있다. 한가지 기법으로 하나의 대역을 저지시키는 기존의 다른 안테나와는 달리, 접힌구조의 기생소자는 하나의 간단한 구조를 통해 이중대역 저지를 만족한다. 접힌구조의 기생소자로 인해 이중대역은 WiMAX, C-band, 그리고 WLAN 대역을 저지시킨다. 제안된 안테나의 대역은 3.1~10.6 GHz에서 전압 정재파비는 이중대역저지 대역인 3.4~4.2 GHz, 5.15~6.00 GHz를 제외한 구간에서 2 이하를 만족한다.
