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.

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.
