초록

본 논문에서는 소형 USB dongle에 적용을 위한 다중 대역 MIMO 안테나를 제안하였다. 제안된 MIMO 안테나는 변형된 미엔더 라인과 역 L형 스터브로 구성되어 있으며, 접지면을 기준으로 서로 대칭적으로 상 하단에 위치한다. 구현된 안테나는 LTE 13, 17 대역(704-787 MHz), DCS/PCS/WCDMA 대역(1.71-2.17 GHz), LTE 7 대역(2.5-2.7 GHz) 대역에서 VSWR 3:1을 만족하였다. 효율 특성은 전체 주파수 대역에서 평균 35 % 이상의 값을 갖고, 상관 계수는 LTE 13, 17 대역에서 0.45 이하, DCS/PCS/WCDMA 및 LTE 7 대역에서 0.1 이하의 값을 갖는다.

This paper proposes a multiband Multi-Input Multi-output(MIMO) antenna for universal serial bus(USB) dongle application. The proposed MIMO antenna consists of a modified meander strip line and inverted L stub. The two radiating elements of the MIMO antenna are symmetrically placed with respect to the center of the ground plane. The fabricated antenna satisfied a VSWR below 3 and an efficiency over 35 % in the LTE band 13, 17(704 MHz-787 MHz), DCS/PCS/WCDMA band(1.71 GHz-2.17 GHz), and LTE band 7(2.5 GHz-2.7 GHz). The envelope correlation coefficient(ECC) has below 0.45 in the LTE band 13, 17 and 0.1 in the DCS/PCS/WCDMA band and LTE band 7, respectively.
