Abstract

The modern society has become entry into the information age after the spread of Internet. In the information age, internet was developed from the wired access to the wireless Internet access. When a surge in demand for wireless Internet access, performance and speed of 2.4 and 5GHz band for Wi-Fi which leads to saturation of the communication was significantly fall. Accordingly, the communication of the 6GHz band for Wi-Fi 6E came to be interested. In this paper, we studied the design and fabrication of microstrip patch antenna to be used in wireless communication systems operating at around 6GHz band. To obtain antenna parameters such as patch size, inter patch space, antenna was simulated by HFSS(High Frequency Structure Simulator). From these parameters, slot microstrip patch antenna is fabricated using FR-4 of dielectric constant 4.4. The characteristics of fabricated patch type microstrip antenna were analyzed by network analyzer.

인터넷이 보급된 이후로 우리 사회는 정보화시대에 진입하게 되었고, 인터넷도 유선인터넷에서 무선인터넷으로 변화하게 되었다. 무선인터넷의 수요가 급증하게 되면서 이전에 Wi-Fi에 이용하던 2.4 및 5GHz 대역의 인터넷 통신은 포화상태에 도달하게 되어 성능과 속도가 급속히 저하하게 되었다. 따라서 속도가 증가된 Wi-Fi 6E에 사용되는 6GHz 대역의 통신이 주목을 받게 되었다. 본 연구에서는 6GHz 대역에서 사용 가능한 패치형 마이크로스트립 안테나를 HFSS(High Frequency Structure Simulator)를 사용하여 특성을 분석하고 안테나를 설계하였다. 설계된 안테나를 유전율 4.4의 FR4 기판을 이용해 안테나를 제작하고, 회로망 분석기를 사용하여 제작된 6GHz 대역용 패치 안테나 동작 특성을 분석하였다.
