Abstract
In this paper, microstrip antenna is designed for industrial-scientific-medical(ISM)band of S-Band. We proposed that radiation element of antenna, which is rectangle patch shape. The feeding structure used L-shaped structure. Center frequency and -l0dB bandwidth are investigated by change of length and width in patch plane. And maximum gain, front to back ratio and 3dB beam width is presented by simulation radiation pattern of antenna in frequency ISM Band. The center frequency is 2.45GHz, band width is
본 논문에서는 S-Band에서의 ISM대역을 위한 마이크로스트립 안테나를 설계하였다. 사각형 패치를 안테나의 방사소자로 제안하고, 급전 방식은 L형 급전구조를 이용하여 광대역 화 하였다. 패치면의 길이와 폭 변화에 따른 중심주파수와 VSWR 2:1 (
