Abstract

In this paper, a microstrip-fed triple-band monopole antenna for WLAN/WiMAX applications was proposed. The proposed antenna is consist of two arc-shaped and one strip line structure, then get the three current path and then designed in order to get triple resonant characteristics. We carried out simulation about parameters. Taking account of coupling effect, Adjusted the length of the two arc-shaped and one strip line, we get the optimized parameters. The proposed antenna is fabricated on an FR-4 substrate, the dielectric constant is 4.4, and total size is $23.5mm(W1){\times}32.0mm(L1){\times}1.0mm(t)$, and its proposed antenna size is $21.0mm(W6){\times}31.0mm(L7)$. From the measured results, return loss of the proposed antenna satisfied return loss 927 MHz (1.844~2.771 GHz), 926 MHz (3.33~4.256 GHz), and 1,415 MHz (5.13~6.545 GHz). And measured results of gain and radiation patterns displayed for operating bands.

본 논문에서는 WLAN/WiMAX 시스템에 적용 가능한 모노폴 안테나를 제안하였다. 제안된 안테나는 두 개의 원호와 한 개의 직선 선로로 설계하여 세 개의 전류흐름을 갖도록 구성하여 세 개 대역의 공진특성을 갖도록 설계하였다. 두 개의 원호 길이와 한 개의 직선 선로의 길이를 상호결합을 고려하려 본 논문에서 요구되는 특성을 얻기 위한 최적화 수치를 얻었다. 제안된 안테나는 $23.5mm(W1){\times}32.0mm(L1){\times}1.0mm(t)$의 유전율이 4.4인 RF-4 기판 위에 $21.0mm(W6){\times}31.0mm(L7)$의 크기로 제작되었다. 측정결과로부터, 927 MHz (1.844~2.771 GHz), 926 MHz (3.33~4.256 GHz), 그리고 1,415 MHz (5.13~6.545 GHz)의 대역폭을 얻었다. 또한 요구되는 삼중대역에서 측정된 이득과 방사패턴의 얻었다.
