Highly Miniaturized and Low impedance Wilkinson Power Divider on RFIC/MMIC for application to IT components of Ocean Engineering

해양 IT 소자에의 응용을 위한 RFIC/MMIC용 초소형 저임피던스 윌킨슨 전력분배기 설계

In this paper we propose low-impedance and miniaturized a wilkinson power divider on MMIC passive component which was fabricated by a novel microstrip line structure employing periodically perforated ground metal (PPGM). The novel microstrip line structure showed much lower impedance and shorter guided-wavelength than conventional one. Using the novel microstrip line with periodically perforated ground metal, a miniaturized 17 ${\Omega}$ power divider was fabricated. The line width of the power divider was 20 ${\mu}m$, and the size of it was 0.110 $mm^2$, which is 21 % of conventional one. The power divider exhibited good RF performances from 10 to 20 GHz.
