Abstract

This paper presents the design method of a planar sleeve monopole antenna on PCB, which has wider bandwidth compared to that of the conventional sleeve monopole antenna, by showing the fact that the sleeve of the conventional antenna can be simplified in structure. The designed and fabricated planar sleeve monopole antenna's structure is very simple, with a monopole adjacent to a small square sleeve on FR4 PCB. The antenna shows 46% wider bandwidth compared to the corresponding 3-dimensional one with nearly omni-directional radiation property.

본 논문에서는 기존의 3차원 구조의 슬리브모노폴 안테나(Sleeve monopole Antenna)를 모노폴과 접지면상의 작은 기생모노폴의 형태로 단순화하여도 비슷한 특성을 보이는 것을 확인하고 PCB상에 보다 광대역인 평면 슬리브모노폴 안테나의 설계 방법에 대해 다룬다. 설계 및 제작된 슬리브안테나는 평면형으로 메인 모노폴과 이에 근접하는 작은 사각형 슬리브로 구성되고 기존의 3차원 슬리브안테나와 비슷한 전방향(omni-directional)특성과 기존보다 46% 더 넓은 대역폭을 나타내었다.
