초록

본 논문에서는 O형 슬롯을 가진 계단 구조의 UWB 마이크로스트립 패치안테나를 제안하고 안테나의 특성을 분석하였다. 안테나의 특성 개선을 위하여 방사소자인 패치면의 크기, O형 슬롯의 반지름 변화, 급전선의 폭과, 사각 슬롯의 폭을 CST 시뮬레이션 프로그램을 이용하여 최적화 하였다. 제안된 안테나는 2.8GHz ~ 11.4GHz 주파수 대역에서 최소 반사손실은 약 -32.39dB 그리고 -10dB 대역폭은 8.6GHz의 대역폭을 특성을 나타냈다.

In this paper, We proposed a UWB microstrip patch antenna with an O-shaped slot of the step structure and analyzed the characteristics of the antenna. In order to improve of frequency properties, size of the patch radiating element, radius change of the O-shaped slot, width of the feed line and a rectangular slot were optimized by CST simulation program. The proposed antenna showed that the 2.8GHz ~ 11.4GHz frequency, the minimum return loss and -10dB bandwidth were -32.39dB and 8.6GHz, respectively.
