Abstract

In this paper, we studied the design and fabrication of double T Structure with CPW antenna at around 5 GHz band.. To improve of frequency properties of antenna, Double T Structure with CPW antenna was simulated by HFSS(: High Frequency Structure Simulator). A double T Structure with CPW antenna was designed and fabricated by photolithograph on an FR4 substrate (dielectric constant of 4.4 and thickness of 1.6 mm). The fabricated A double T Structure with CPW antenna showed a center frequency, the minimum return loss and impedance were 5.29GHz, -34dB, and 390MHz, $49.6{\Omega}$ respectively.

본 논문에서는 5GHz 대역의 이중 T 구조를 갖는 CPW 안테나를 연구하였다. 안테나에 대한 주파수와 반사손실에 관한 파라미터 특성을 HFSS(: High Frequency Structure Simulator)를 통해 분석하고 이것을 이용하여 안테나를 설계하였다. 시뮬레이션 결과를 바탕으로 5GHz 대역에서 사용 가능한 이중 T 구조 CPW 안테나를 설계하고, 설계 된 안테나를 유전율 4.4, 두께 0.8mm인 FR4-epoxy 기판을 사용 하여 포토리소그래피 방법으로 안테나를 제작하였다. 제작된 안테나는 최종적으로 회로망 분석기(Network Analyzer)를 통해 안테나 특성을 분석하였다. 제작된 CPW 이중 T 구조 안테나는 중심주파수 5.29GHz, 입력반사손실 -34dB, 임피던스 $49.6{\Omega}$의 결과 값을 보였다.
