물결모양 구조를 갖는 광대역 슬롯 안테나

초록

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 70×70×1.6 mm, 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.
