Abstract

A rectangular ceramic dielectric antenna, placed on the top of a ground plane and fed by coaxial probe, is analyzed by using the finite element method. To verify the proposed code, a rectangular ceramic dielectric antenna was fabricated and the characteristics of antenna were measured. The numerical data obtained is in good agreements with experimental result. Thus we checked the validity of our FEM code, and it can be possible to extend the analysis of the arbitrary 3-D antenna on a ground plane fed by coaxial probe.

본 논문에서는 유한요소법(FEM. Finite Element Method)을 적용하여 coaxial feeding 구조를 가진 접지면 위에 부착된 직육면체형 세라믹 유전체 안테나를 해석하였다. 제안된 프로그램의 타당성을 검증하기 위하여 시제품을 제작하여 안테나 특성의 설험 값과 본 프로그램의 해석치를 비교하였으며 잘 일치함을 확인할 수 있었다. 이로써 본 유한요소 프로그램을 검증할 수 있었고, coaxial feeding 구조를 가진 접지면 위에 부착된 임의의 3차원 안테나 구조불 해석에도 확장이 가능함을 알 수 있었다.
