Abstract

In this paper, a wideband slot antenna with corrugated structure antenna is proposed. The proposed antenna consists of a ground plane with corrugated slot and microstrip feed-line. Even with a limited dimension of $70{\times}70{\times}1.6mm$, the proposed antenna has wide bandwidth due to the longer current path formed by the corrugated slot structure. Measured bandwidth(10 dB return loss) and fractional bandwidth of the proposed antenna are 2,180 MHz(2.5~4.68 GHz) and 60.7 % at the center frequency of 3.59 GHz. The proposed antenna has an omni-directional radiation pattern and measured gains and average efficiency were 3.48~5.83 and dBi, 81.55 %, respectively.

본 논문에서는 물결모양 구조를 갖는 광대역 슬롯 안테나를 제안하였다. 제안된 안테나는 물결모양 슬롯 구조를 가지는 접지면과 마이크로스트립 급전선으로 이루어져 있다. $70{\times}70{\times}1.6mm$의 한정된 크기에서 제안된 안테나는 물결모양 슬롯 구조를 통해 전류의 경로를 길게 하여 보다 동작주파수를 낮추었으며, 광대역의 대역폭을 갖는다. 안테나의 측정된 10 dB 반사손실 대역폭은 2,180 MHz(2.5~4.68 GHz)이며, 중심주파수 3.59 GHz에서 비대역폭 60.7 %를 가진다. 제안된 안테나는 전방향성 방사 패턴을 가지며, 측정된 이득과 평균효율은 3.48~5.83 dBi, 81.55 %의 값을 갖는다.
