양면형 가유전체 기판구조를 이용한 브랜치 라인 결합기의 설계

다국어 초록 (Multilingual Abstract)

In this paper, the design of a branch line coupler using a double-sided artificial dielectric substrate (DSADS) structure is described. Lots of metalized via-holes in the artificial dielectric substrate (ADS) structure induce an additional equivalent capacitance and effective permittivity, which lead a length-reduction of the transmission line on ADS. Beside this effect, the ADS is folded for half size, and the transmission line is designed on this folded or double-sided ADS with the transmission characteristics preserved. In order to show an application example of the DSADS to wireless circuit design, this paper designs a microwave branch line coupler on the proposed DSADS. The designed coupler has the half size as compared to the case of single-sided ADS, while the electrical performances in matching, isolation, power division, and coupling are still preserved as an required level. The paper also provides the measured data.
