摘要
Abstract
A new equivalent circuit modelwas established and a new parameter extractionmethodwhich could exactly describe the structure of composite right/left-handed transmission line with many nodeswas put forward. The new method of parameter extractionwas proved by using the simulation software to study the consistency of physical model and equivalent circuit model. Theleaky-wave antenna object of composite right/left-handed transmission linewas designed and made referring to the new equivalent model.Sparameters of the antenna were measuredbythenetwork analyzer. Results show,thebeam direction of themicrostrip leaky-wave antennawithright/left-handed transmission linecan changewith frequency change,the boundednessof traditionalleaky-wave antenna onlyscan the first half of the spaceis changedandthe scan scopeexpandstothe whole space. Besides, the energy in each beam direction is more uniform. Its size decreases by about 50% compared with traditional leaky-wave antenna.关键词
