Abstract

In this paper, the printed-sleeve monopole antenna which has the small size and the broadband characteristics, is presented and its radiation characteristics are investigated. To conform the broadband characteristics of the proposed antenna, the experimental antenna is designed, fabricated, and its radiation characteristics are measured in PCS band (1.75 GHz${\~}$1.87 GHz). It is shown that the designed antenna has the non-directional pattern in the horizontal plane, the directional pattern in the vertical plane, VSWR less than 1.5, and gain in 2.14 dBi${\~}$3.4 dBi. From these results, the proposed antenna is conformed as a broadband antenna which can be used for the mobile communication indoor antenna extensively.

본 논문에서는 소형${\cdot}$광대역 특성을 갖는 프린트 슬리브 모노폴 안테나(printed-sleeve monopole antennas)를 제안하고 복사 특성을 고찰하였다. 제안된 안테나의 광대역 특성을 확인하기 위하여 PCS 대역(1.75 GHz${\~}$l.87 GHz)에서 안테나를 설계 제작하고 복사 특성을 측정하였다. 제안된 안테나는 수평면내 무지향성, 수직면내 지향성 특성을 가지며, 정재파비는 사용 주파수 대역에서 1.5이하, 안테나 이득은 2.14 dBi${\~}$3.4 dBi로 나타났다. 측정결과로부터 제안된 안테나는 이동 통신 실내용 광대역 안테나로 널리 사용될 수 있음을 확인하였다.
