초록

본 논문은 2.4 GHz 와 5 GHz 대역에서 802.11n 규격에 사용가능한 이중 공진 PIFA(Planar Inverted F-Antenna)를 제안하였다. 이중 공진을 위해 2.4 GHz 대역에서는 패치, 5 GHz 대역에서는 U-형 슬랏을 이용하여 PIFA를 설계하였다. 단락판과 급전핀의 위치, 단락판의 폭, U-형 슬랏의 두께, U-형 슬랏의 위치를 변경시키며 HFSS(High Frequency Structure Simulation)를 이용하여 안테나의 특성변화를 조사하였다. 실제 시제품을 제작하여 측정한 값과 시뮬레이션 값을 비교 분석한 결과, U-형 슬랏의 위치가 급전핀과 멀어질수록, 그 두께가 얇을수록 안테나의 특성이 좋아지는 것을 알 수 있었다.

This paper presents the dual resonance PIFA(Planar Inverted F-Antenna) which satisfies the requirements of the 802.11n standard at both 2.4 GHz and 5 GHz frequency bands. Patch for 2.4 GHz and U-Type slot for 5 GHz were used for dual resonance, respectively. In this paper, the characteristics of an antenna were investigated by varying locations of short plate and feed point, the width of the short plate, the thickness and the location of U-Type slot. To investigate the characteristics of the PIFA, HFSS(High Frequency Structure Simulation) for the simulation was used. And the measurement results of a fabricated PIFA were compared with the simulated ones. The measurement and simulation results show that good dual resonance characteristics as the thickness of U-type slot decreases and when the location of U-type slot is far from the feed point.
