Abstract

In this paper, an antenna accessible to the Hepta-Band (GPS, DCS, PCS, UMTS, Wibro, Bluetooth and S-DMB) is designed and fabricated. To get broadband characteristics with small size, we propose a structure of Coplanar Waveguide-fed with Ground, which is based on a monopole antenna. Simulation is performed by adjusting the size of distance between a length of radiation patch and ground plane. The designed antenna satisfies the frequency bandwidth of 1.430Hz$\sim$2.9GHz(67.89%), the gain of $1.3{\sim}3.7dBi$ and an omni-directional radiation pattern at VSWR<2.

본 논문에서는 GPS, DCS, PCS, UMTS, Wibro, Bluetooth, S-DMB대역에서 동작 가능한 안테나를 설계하고 제작하였다. 최대한 적은 부피의 안테나로 광대역 특성을 얻기 위해 모노폴 안테나를 기반으로 CPWG(Coplanar Waveguide-fed with Ground) 급전 구조를 사용하였다. 방사패치의 길이와 방사패치와 접지면 간의 간격을 조정하며 시뮬레이션 하였으며, 최적화된 파라미터를 가지고 제작하였다. 제작된 안테나는 VSWR<2에서 1.430Hz$\sim$2.9GHz(67.89%)의 대역폭과 $1.3{\sim}3.7dBi$의 이득 및 전방향성(Omni-directional) 방사패턴을 얻었다.
