摘要：

A novel compact branch-line coupler using substrate integrated suspended line (SISL) technology is proposed in this letter. In order to reduce the size of conventional branch-line coupler, we propose a novel slow wave structure, which is composed of high-low impedance lines cascaded in meander line configuration, and a 62% size reduction has been achieved. Moreover, fabricated by using standard printed circuit board process, the proposed compact SISL branch-line coupler has advantages of self-packaging, low cost and light weight.
