Abstract

This paper describes the design, fabrication, and measurement of a compact hexa-band coupling antenna for 4G mobile handset using a small element with two slots. In order to obtain sufficient bandwidth (LTE700, GSM850, GSM900, GSM1800, GSM1900, UMTS) with a Voltage Standing Wave Ratio $(VSWR){\leq}3:1$, two slots are inserted in the small element, and coupling patch is used. The measured result of the fabricated antenna provides 410MHz bandwidth form 0.688 to 1.098GHz and 643 MHz bandwidth form 1.607 to 2.250GHz (${\leq}VSWR 3:1$) with the gain ranging from -0.52 to 4.68 dBi. Also, a good radiation pattern is achieved within the hexa-band (0.698-0.960GHz and 1.710-2.170GHz) range.

본 논문에서는 LTE 700, GSM 850, GSM 900, GSM 1800, GSM 1900, UMTS 대역에서 동작 가능한 안테나를 설계 제작하였다. 작은 크기의 안테나로 광대역 특성을 얻기 위해 다중대역 모노폴 안테나를 기반으로 커플링 구조를 사용하였고 두 개의 slot을 삽입하여 hexa-band 대역폭 특성을 구현하였다. 시뮬레이션에 의한 최적화된 파라미터를 가지고 제작 하였고 제작된 안테나는 $VSWR{\leq}W3:1$에서 Low 주파수대역 410Hz 대역폭 (0.688-1.098GHz)과 High 주파수대역 643MHz 대역폭 (1.607-2.250GHz)이 측정되어 hexa-band(0.698-0.960GHz, 1.710-2.170GHz) 대역폭을 만족하고 높은 이득 (-0.52-4.68dBi) 및 전방향성 (Omni-directional) 방사 패턴을 얻었다.
