Abstract

In this paper, we propose a triple band WLAN antenna for Wi-Fi 6E band with DGS. The proposed antenna has the characteristics required frequency band and bandwidth by considering the interconnection of two strip lines and three areas on the ground place. The total substrate size is 31 mm (W) × 50 mm (L), thickness (h) 1.6 mm, and the dielectric constant is 4.4, which is made of 22 mm (W6 + W4 + W5) × 43mm (L1 + L2 + L3 + L5) antenna size on the FR-4 substrate. From the fabrication and measurement results, bandwidths of 340 MHz (1.465 to 1.805 GHz) for 900 MHz band, 480 MHz (2.155 to 2.635 GHz) for 2.4 GHz band and 1950 MHz (4.975 to 6.925 GHz) for 5.0/6.0 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.

본 논문에서는 WLAN 시스템에 활용 할수 있도록 DGS를 적용하여 삼중대역 안테나를 제안하였다. 제안된 안테나는 두 개의 스트립 선로와 접지면에 세 개의 영역을 삽입하여 요구하는 주파수 대역과 반사손실 특성을 얻었다. 제안된 안테나는 22.0 mm(W) × 54.9 mm(L1)의 크기와 두께(h) 1.6 mm, 그리고 비유전율이 4.4인 FR-4 기판 위에 22 mm(W6+W4+W5) × 43 mm(L1+L2+L3+L5)의 크기로 설계되었다. 제작 및 측정결과로부터, -10dB 기준으로 900 MHz 900 MHz 대역에서 108 MHz (0.908~1.016 GHz), 2.4 GHz 대역에서 360 MHz (2.276~2.636 GHz), 그리고 5.0/6.0 GHz 대역에서 2,484 MHz (4.904~7.388 GHz)의 대역폭을 얻었다. 또한 요구되는 주파수 삼중대역에서 이득과 방사패턴 특성을 측정하여 나타내었다.
