Abstract

In this paper, we studied the design and fabrication of $2{\times}2$ microstrip array antenna at around 5 GHz band.. To improve of frequency properties of antenna, feed microstrip patch antenna was simulated by HFSS(High Frequency Structure Simulator). A $2{\times}2$ array antenna was designed and fabricated by photolithograph on an FR4 substrate (dielectric constant of 4.4 and thickness of 1.6 mm). The fabricated $2{\times}2$ array antenna showed a center frequency, the minimum return loss and bandwidth were 5.3 GHz, -24dB, and 390MHz, respectively.

본 논문에서는 5GHz 대역의 $2{\times}2$ 배열 안테나를 연구하였다. 선로 방식으로는 마이크로 스트립 방식을 채택하였고 안테나 제작 및 특성을 측정하였다. 각 선로방식의 안테나에 대한 주파수와 반사손실에 관한 파라미터 특성을 HFSS(High Frequency Structure Simulator)를 통해 분석하고 이것을 이용하여 안테나를 설계하였다. 시뮬레이션 결과를 바탕으로 $2{\times}2$ 마이크로스트립 배열 안테나를 설계하고, 유전율 4.4, 두께 1.6mm인 FR4-epoxy 기판을 사용 하여 포토리소그래피 방법으로 안테나를 제작하였다. 제작된 $2{\times}2$ 배열 안테나는 중심 주파수 5.3GHz, 입력반사손실 -24dB, 대역폭 390MHz 의 동작특성을 보였다.
