Abstract

An inductive loaded microstrip patch antenna using aperture coupled feeding is designed and an impedance bandwidth enhancement method using a shunt stub is investigated. The -10 dB impedance bandwidth of the AIMPA with a shunt stub is increased up to about 5.51 %. The impedance bandwidth of the corresponding AIMPA without a shunt stub is 2.4 %. The increase of the impedance bandwidth of the AIMPA with a shunt stub is about 129.6 % compared to that of the corresponding AIMPA without a shunt stub.

개구면 결합 급전 방법을 이용하여 inductive loaded 마이크로스트립 패치 안테나를 설계하고 병렬 스터브를 이용하여 임피던스 대역폭을 넓히는 방법에 대해 연구하였다. 급전선로에 병렬 스터브를 삽입하여 AIMPA의 임피던스 대역폭을 확장시켰다. 병렬 스터브를 삽입한 AIMPA의 -10 dB 임피던스 대역폭은 5.51 %로 병렬 스터브를 삽입하지 않은 AIMPA의 임피던스 대역폭 2.4 %와 비교하여 대역폭이 약 129.6 % 증가함을 볼 수 있었다. -10 dB 대역폭 내에서 방사 패턴의 전체적인 모양은 크게 변화하지 않음을 확인하였다.
