Simple equivalent-circuit models based on closed-form expressions are also established, from which various lumped-element impedance-transforming transitions are investigated. Examples for using the proposed transitions in the design of antenna feeding structures are also demonstrated, and successful size reduction has been achieved.application/pdf511475 bytesapplication/pdfzh-TWAntenna feeding structureimpedancetransforming transitionjournal articlehttp://ntur.lib.ntu.edu.tw/bitstream/246246/200611150121328/1/5318.pdf
