초록

본 논문에서는 Sub-6G 대역을 포함한 WLAN 시스템에 적용가능한 멀티밴드 안테나를 제안하였다. 제안된 안테나는 4개의 경로를 갖는 스트립 선로와 임피던스 매칭을 위해 슬롯을 갖는 부분 접지면으로 구성되어 있다. 제안된 안테나는 48.0 mm(W)×50.0 mm(L)의 크기와 두께(h) 1.0 mm, 그리고 비유전율이 4.4인 FR-4 기판 위에 26.0 mm(W2)×42.0 mm(L1+L2+4.0 mm+L8+L9)의 크기로 설계되었다. 제작 및 측정 결과로부터, -10dB 기준으로 900 MHz 대역에서는 115 MHz (0.825~0.940 GHz), 2.4 GHz 대역에서는 210 MHz (2.29~2.50 GHz), 3.5 GHz 대역에서는 270 MHz (3.45~3.72 GHz), 그리고 5.0 GHz 대역에서는 930 MHz (4.95~5.88 GHz)의 대역폭을 얻었다. 또한 요구되는 주파수 삼중대역에서 이득과 방사패턴 특성을 측정하였다.

In this paper, we propose mult-band antenna included Sub-6 GHz band for WLAN system. The proposed antenna has the fourth strip line and slot in the partial ground plane to obtain impedance matching. The total substrate size is 48.0 mm (W)×50.0 mm (L), thickness (h) 1.0 mm, and the dielectric constant is 4.4, which is made of 26.0 mm (W2)×42.0 mm (L1+L2+4.0(L1+L2+4.0 mm+L8+L9) antenna size on the FR-4 substrate. From the fabrication and measurement results, bandwidths of 115 MHz (0.825 to 0.940 GHz) for 900 MHz band, 210.0 MHz (2.29 to 2.50 GHz) for 2.4 GHz band, 270.0 MHz (3.45 to 3.72 GHz) for 3.5 GHz band, and 930.0 MHz (4.95 to 5.88 GHz) for 5.0 GHz band were obtained on the basis of -10 dB. Also, gain and radiation pattern characteristics are measured and shown in the frequency triple band as required.
