Abstract

In this paper, we propose an antenna that improves narrow band characteristics which is a disadvantage of inverted-F type antenna and utilizes the structural advantages of small size and low profile by modifying the inverted-F type antenna structure and applying CPW feeding method. Experimental results show that the broadband characteristic of about 40% at the center frequency of 3 GHz is seen, and it is found that the narrow band characteristic which is a disadvantage of the conventional inverted F antenna can be improved. The radiation pattern showed almost omnidirectional characteristics and the maximum gain was about 2.0dBi.

본 논문에서는 역 F형 안테나 구조를 변형시키고 CPW급전 방법을 적용함으로써 역 F형 안테나의 단점인 협대역 특성을 개선하고, 소형 그리고 저자세의 구조적인 장점을 살리는 안테나를 제안하고자 한다. 실험 결과 중심주파수 3GHz에서 약 40%의 광대역 특성이 있음을 보여, 기존 역 F형 안테나의 단점인 협대역 특성을 개선할 수 있음을 알 수 있었다. 방사패턴은 거의 전방향 특성을 보였고 최대 이득은 약 2.0dBi이다.
