Abstract

In this paper, a compact CPW-fed antenna for 2.45 GHz band WLAN applications is presented. The proposed antenna which has a geometry of folded stub and slot is fabricated into an inexpensive FR-4 substrate that has a dielectric constant of 4.2 and a thickness of 1.0 mm with optimized parameters obtained by simulation, and then measured. From measured result, we confirmed available operation as antenna for WLAN applications by obtaining the return loss level of < -10 dB in the frequency band of 2.4-2.484 GHz.

본 논문에서는 2.4 GHz 무선랜 대역에서 사용이 가능한 CPW 소형 안테나를 제안하였다. 제안된 안테나는 스터브와 슬롯이 모두 접혀진 구조로써 모의실험을 통하여 최적화된 파라미터 수치로 비유전율이 4.2, 두께가 1.0 mm인 저렴한 FR-4 기판 상에 제작하여 측정하였다. 측정한 결과 주파수 2.4-2.484 GHz 대역에서 -10 dB 이하의 반사손실 값을 얻음으로써 2.4 GHz 무선랜에서 사용할 수 있음을 확인하였다.
