Abstract

The modern society has become full-fledged entry into the information age since 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, efficiency and performance of 2.4GHz band which leads to saturation of the communication was significantly fall. Accordingly, the communication of the 5GHz band came to be interested. In this paper, we studied the design and fabrication of u-slot microstrip patch antenna to be used in wireless communication systems operating at around 5GHz band. To obtain antenna parameters such as patch size, inter patch space, antenna was simulated by HFSS(High Frequency Structure Simulator). From these parameters, u-slot microstrip antenna is fabricated using FR-4 substrate of dielectric constant 4.4. The characteristics of fabricated antenna were analyzed by network analyzer.

인터넷이 보급된 이후로 현대사회는 본격적인 정보화시대에 진입하게 되었다. 정보화시대에 발 맞춰 인터넷은 유선인터넷에서 무선인터넷으로 발전하게 되었다. 무선인터넷의 수요가 급증하자 기존에 사용된 2.4GHz 대역의 통신은 포화상태에 이르게 되었으며 효율과 성능이 현저히 떨어지게 되었다. 이에 따라 5GHz 대역의 통신이 주목을 받게 되었다. 본 논문에서는 5GHz대역의 통신이 가능한 U-slot 마이크로스트립 안테나를 HFSS(High Frequency Structure Simulator)를 통해 분석 및 설계하였다. 설계된 안테나를 유전율 4.4의 FR4-epoxy기판을 이용해 제작하고 최종적으로 회로망 분석기(Network Analyzer)를 통해 안테나 특성을 분석하였다.
