Abstract

Bandwidth enhancement technique for a proximity coupled patch antenna is investigated. The bandwidth and radiation characteristics of a proximity coupled patch antenna with an integrated impedance matching network printed on substrates with various dielectric constants and thicknesses are compared to those of a proximity coupled patch antenna without an impedance matching network. The bandwidth of a proximity coupled patch antenna with an integrated impedance matching network is greatly increased than that of a proximity coupled patch antenna without an impedance matching network without the degradation of radiation characteristics.

근접 결합 급전 방식을 이용한 마이크로스트립 패치 안테나의 급전 선로에 임피던스 정합기를 집적하여 대역폭을 확장하는 방법에 대하여 연구하였다. 여러 가지 유전상수와 두께를 가지는 기판을 사용한 근접 결합 급전을 이용한 패치 안테나에 임피던스 정합기를 집적한 경우와 임피던스 정합기를 사용하지 않은 경우의 대역폭과 방사특성을 비교하였다. 임피던스 정합기를 사용한 경우가 사용하지 않은 경우에 비하여 방사특성의 저하 없이 대역폭이 크게 증가함을 볼 수 있었다.
