Abstract

In this paper, a SWB (Super-WideBand) dipole antenna with self-complementary structure is proposed for signal intelligence. The proposed antenna consists of a self-complementary dipole antenna and a tapered balun for balanced feeding. The measured -10 dB reflection bandwidth of the proposed antenna is more than 28:1 (0.73-20 GHz) and 3 dB axial ratio bandwidth is 3.25:1 (1.91-6.22 GHz) with RHCP (Right Hand Circular Polarization) at +z direction. The measured radiation patterns are omni-directional in lower frequency band and bi-directional in higher frequency band. The measured peak gain within -10 dB reflection bandwidth varies from 2.83 dBi to 7.66 dBi.

본 논문에서는 자기상보 구조를 갖는 신호정보 수집용 초광대역 다이폴 안테나를 제안하였다. 제안된 안테나는 한 쌍의 자기상보 구조의 다이폴 안테나와 평형 급전을 위한 테이퍼드 발룬(tapered balun)으로 구성되어 있다. 제안된 안테나의 -10 dB 이하 반사계수 대역폭 비는 28:1(0.73-20 GHz) 이상이며, 3 dB 이하 축비 대역폭 비는 3.25:1(1.91-6.22 GHz)로 +z축 방향에서 RHCP (Right Hand Circular Polarization) 특성을 나타낸다. 또한 저주파 대역에서는 무지향성, 고주파 대역에서는 지향성 특성을 나타내었고, 동작주파수 대역 내에서 최대이득은 2.83-7.66 dBi로 분포함을 확인하였다.
