Design and implementation of miniaturized microstrip branch-line directional coupler
摘要
Abstract
A design scheme of a miniaturized microstrip branch-line directional coupler is proposed. The problem of the large size of the traditional microstrip branch-line directional coupler was solved by the way of structural equivalence. The optimi-zation simulation design was carried out by using HFSS software. In order to validate the feasibility of the scheme,the prototype of the proposed microstrip branch-line directional coupler for L band maritime satellite communication was fabricated and mea-sured. The size of the miniaturized microstrip branch-line directional coupler is reduced by 51% in comparison with traditional microstrip branch-line directional coupler. The measured results have a good agreement with the simulated ones.关键词
