Abstract

In this paper, a CPW fed slot antenna with novel broadband feed structure is presented. To enhance the impedance bandwidth of the slot antenna we proposed the broadband feed structure of new bow-tie slot which is combined with four λ/2 rectangular radiation slot and inductively coupled. The measured 10 dB impedance bandwidth is about 60 %(5.2∼9.4 GHz) and the simulated antenna gain is about 6 dBi at 7.36 GHz.

본 논문에서는 새로운 광대역 급전구조를 활용한 초광대역 CPW 급전 슬롯안테나를 제안하였다. 임피던스 대역폭을 확장하기 위해 새로운 보우-타이 슬롯의 광대역 급전부를 사용하였고 λ/2 직사각형 방사슬롯 4개와 inductively coupling 방식의 급전 구조로 되어 있다. 측정된 10 dB 임피던스 대역폭은 약 60 %(5.2~9.4 GHz)이며 모의 실험한 안테나 이득은 7.36 GHz에서 약 6 dBi를 나타내고 있다.
