Abstract
본 논문에서는 위성 DMB용 슬롯을 가지는 단일 급전 형태의 마이크로스트립 안테나를 제안하고 안테나를 제작하여 특성을 분석하였다. 안테나의 특성 향상을 위하여 방사소자인 패치의 크기, 급전선 길이, 슬롯의 크기 등의 파라미터가 미치는 영향을 HFSS로 분석하였다. 설계 제작된 단일 급전 형태의 마이크로스트립 안테나는 측정결과 2.64GHz의 중심주파수와 최소 반사손실은 약 -34.67dB 그리고 -10dB 대역폭은 180MHz의 대역폭 특성을 각각 보여 주었다. In this paper, we proposed and fabricated the single feed microstrip patch antenna with slot for S-DMB(Satellite-Digital Multimedia Broadcasting). In order to improve of frequency properties, patch size, feed length, and slot size were investigated by HFSS simulation program. The manufactured single feed microstrip patch antenna with slot showed that the measured center frequency, the minimum return loss and -10dB bandwidth were 2.64GHz, -34.67dB and 180MHz, respectively.
