초록

이 논문은 저주파수 영역에서 광대역을 실현하기 위해 대칭형 미앤더 급전 선로를 이용한 사다리꼴 평면 UWB 안테나의 설계를 제안한다. 제안된 설계 안테나의 크기는 $15.5{\times}2.1{\times}1.6mm^3$이며, 설계에 고려된 유전체는 4.4의 복소 비유전율을 가진다. 계산된 대역폭은 9.52 GHz($1.31{\sim}10.83$ GHz)이고, 측정된 대역폭은 반사 손실 -10 dB 이하에서 9.1 GHz($1.5{\sim}10.6$ GHz)이며, 이 대역은 UWB 안테나 대역폭을 만족한다. 또한, 시뮬레이션상 복사 패턴과 측정 패턴이 각각의 주파수에서 서로 잘 일치하는 것을 보여주고 있다.

This paper presents a design for trapezoidal planar UWB(Ultra Wide-band) antenna using symmetry meander line to realize broad bandwidth at low frequency region. The size of proposed design antenna is $15.5{\times}21{\times}1.6mm^3$ and dielectric substrate considered in design has 4.4 of relative permittivity. The calculated bandwidth is from 1.31 GHz to 10.83 GHz and the measured return loss is 1.5 GHz to 10.6 GHz at -10 dB below, and satisfies with the UWB antenna's bandwidth. The simulated and measured radiation patterns show fine agreement with each other at each frequency.
