초록

본 논문에서는 마이크로스트립 급전 구조와 네 개의 분기 선로 그리고 접지면에 슬릿을 갖도록 설계하여 WLAN과 WiMAX 시스템에 적용 가능한 4중 대역 안테나를 설계 및 제작하였다. 제안된 안테나는 18.0 mm(W) × 50.0 mm(L) × 1.0 mm(h)의 유전체 기판 위에 16.0 mm(W1) × 48.0 mm (L8)의 크기로 설계하였으며 18.0 mm(W) × 18.7 mm(L6) 접지면에 2.9 mm(W7) × 4.0mm(L7)의 슬릿을 삽입하여 설계하였다. 제작 및 측정결과로부터 -10dB 기준으로 900 MHz에서는 60.8 MHz (873.0~933.8 MHz), 2.4 GHz 대역에서는 310 MHz (2.33~2.64 GHz), 3.4 GHz 대역에서는 420 MHz (3.39~3.81 GHz) 그리고 5.0 GHz 대역에서는 2,070 MHz (4.62~6.69 GHz) 대역폭을 얻었다. 또한 무반사실의 측정결과로부터 4중대역에서 이득과 방사패턴 특성을 나타내었다.

In this paper, we designed a four-band antenna that can be applied to WLAN and WiMAX systems by designing a microstrip feeding structure, four branch lines and a slit on the ground plane. The proposed antenna is designed with a size of 16.0 mm (W1) × 48.0 mm (L8) on a dielectric substrate of 18.0 mm (W) × 50.0 mm (L) × 1.0 mm(h). and a slit of 2.9 mm (W7) × 4.0 mm (L7) is inserted into the ground plane of 18.0 mm (W) × 18.7 mm (L6). Based on -10 dB production and measurement results, it obtained 60.8 MHz (8,730~9,338 MHz), 310 MHz (2.33~2.64 GHz) in the 2.4 GHz band, 420MHz (3.39~3.81 GHz) in the 3.4 GHz band, and 2,070 MHz (4.62~6.69 GHz) in the 5.0 GHz. In addition, the gain and radiation pattern characteristics of the quadrant band are measured from the measurement results anechoic chamber.
