Abstract

In this paper, a compact slot antenna for 2.4GHz ISM band applications has been designed. The folded slot with some additional meander sections are used in the design of the antenna within the restricted PCB space. The operating frequency band and the fractional bandwidth of the antenna is about 2.32~2.58 GHz and 11%, and the radiation patterns within the operation bandwidth are almost same. Also, the radiation efficiency and gain of the antenna is more than 49% and 1.2 dBi respectively. To check the validity of the design result, the measurement and simulation results are compared and presented.

본 논문에서는 2.4 GHz ISM 밴드용 소형 슬롯 안테나를 설계하였다. 안테나의 구조는 제한된 PCB 공간을 활용하여 안테나를 설계할 수 있도록 하기위해 폴디드 슬롯 안테나에 부가적인 미앤더 슬롯이 도입된 형태가 이용된다. 제작된 안테나의 동작 주파수 범위는 2.32~2.58 GHz로서 비 대역폭이 11%이고, 동작 대역폭 범위에서 다이폴 안테나와 유사한 방사패턴이 유지된다. 또한 제작된 안테나는 49% 이상의 방사효율과 1.2dBi 이상의 이득을 갖는다. 설계 결과의 검증을 위해 모의실험 결과와 측정 결과를 비교하여 제시하였다.
