Abstract

In this paper, we proposed a meander sleeve monopole antenna for low earth orbit satellite communications. The antenna has broadband property with the planar monopole and ground of meander sleeve. Monopole and ground conductors of the antenna are on the same plane, and exited through coaxial cable feeding. In order to confirm the property of antenna parameters, it was used a commercial software, HFSS, For the antenna fabrication, a FR4 dielectric substrate has a dielectric constant of 4.4 was used. The size of the antenna was $600mm{\times}20mm{\times}1.6mm$. Frequency band of the fabricated antenna was 130MHz~151MHz, and the bandwidth was 20MHz. Measurement results of the fabricated antenna, the return loss is more than -10dB return loss in the band could be obtained. Radiation pattern has a maximum gain of 2.64dBi value.

본 논문은 저궤도 위성 통신을 위한 미앤더 슬리브 모노폴 안테나를 제안하였다. 안테나는 평면 모노폴과 미앤더 슬리브의 그라운드와 함께 광대역 특성을 갖는다. 안테나의 모노폴 및 그라운드 도체는 동일 평면상에 있으며 동축 케이블을 이용한 공급을 통해 급전하였다. 안테나의 파라미터 변수의 특성을 확인하기 위해 상용 소프트웨어인 HFSS를 사용하였으며, 안테나 제조를 위해 유전상수가 4.4인 FR4를 사용하였다. 안테나의 크기는 $600mm{\times}20mm{\times}1.6mm$이다. 제작된 안테나의 주파수 대역은 130MHz~151MHz이고, 대역폭은 20MHz이다. 안테나의 측정결과, 반사손실은 -10dB 이상의 대역에서의 반사 손실을 얻을 수 있었다. 방사 패턴의 최대 이득은 2.64dBi이다.
