Abstract

This paper presents the improving impedance charactersitics of a planar monopole antenna with a vertical ground plane. For improving impedance characteristics, we used the effect of a vertical ground plane. To analyze the effect of vertical ground plane, we proposed the dipole antenna mode. the impedance characteristics of planar monopole antenna are improved by correlation between monopole antenna and vertical ground plane, based on each operating mode. Our analysis indicates can improve the impedance characteristics of varying planae monopole antennas.

본 논문은 수직 접지면을 갖는 평판형 모노폴 안테나의 임피던스 특성 개선에 관한 논문이다. 평판형 모노폴 안테나의 임피던스 특성 개선을 위해 기존 연구된 방사체 구조 변형 외에 수직 접지면의 영향을 이용하였다. 수직 접지면의 영향을 분석하기 위해 기존 연구인 보조 공진기 모드 이외에 다이폴 안테나 모드를 제안하였다. 수직 접지면의 각 동작 모드를 기반으로, 모노폴 안테나와 수직 접지면 사이의 임피던스 특성 상관관계를 이용하여 평판형 모노폴 안테나의 임피던스 특성을 개선하였다. 개선 방법은 안테나의 급전 위치 변경 및 수직 접지면의 면적 변화이다. 본 분석 결과는 수직 접지면을 갖는 다양한 평판형 모노폴 안테나의 임피던스 특성을 개선 및 분석할 수 있을 것으로 기대 된다.
