초록

이동통신 기술의 발전으로 다양한 통신서비스가 출현됨으로 인해 하나의 안테나로 다중 통신 서비스를 지원하는 광대역 안테나를 필요로 하고 있다. 본 논문에서는 WiFi, LTE 2300/2500, WiMAX 등 기존의 통신 서비스에 5G의 저주파수 대역인 3.3~5.0 GHz의 통신서비스를 모두 지원할 수 있는 평판형 슬롯 광대역 안테나를 제안하고자 한다. 시뮬레이션을 통해 최적화된 안테나 설계 파라미터를 구하고, 안테나를 제작하여 주파수 대역폭이 1.96~6.01 GHz(S11 < -10 dB)인 안테나를 구현하였고, 안테나의 방사패턴 및 이득을 제시하였다. 제안하는 안테나는 LTE, Wifi, WiMAX, 5G 저주파 대역의 서비스를 모두 제공할 수 있는 다중 대역 안테나로 건물 내 또는 건물 밀집지역, 선박 등 전파 음영지역에서 중계기용 안테나로 활용이 가능할 것으로 사료된다.

As various communication services have emerged due to the development of mobile communication technology, there is a need for a wideband antenna supporting multiple communication services with one antenna. In this paper, we propose a planar slot wideband antenna that can support all the communication services of 3.1~4.99GHz, the low frequency band of 5G, in addition to the existing communication services such as WiFi, LTE 2300/2500, and WiMAX. Through the simulation, the optimized antenna design parameters were obtained, and the antenna was fabricated to implement an antenna with a frequency bandwidth of 1.96~6.01GHz (S11 <-10dB) and presented the radiation pattern and gain of the antenna. The proposed antenna is a multi-band antenna that can provide all the services of LTE, Wifi, WiMAX, and 5G low frequency bands. It can be used as a repeater antenna in radio shadow area such as buildings, dense areas, and ships.
