This year, based on the previous year’s research results, we completed the design and analysis for a coplanar waveguide (CPW)-fed microstrip antenna array. First the self-admittance of a single-element and input impedance of a two-element array are calculated by using IE3DTM. The mutualadmittance is obtained by substituting the input impedance of a single-element and that of a two-element into the transmission-line theory. With self- and mutual-admittances on hand, we then apply transmission-line theory to find the input impedance of a multi-element patch array. Using the above method, we designed a three-element patch array. Experiments verified the proposed approach and proved that the input impedance is greatly affected by the mutual-admittance.application/pdf71392 bytesapplication/pdfzh-TW國立臺灣大學電機工程學系暨研究所共面波導微帶天線陣列Coplanar WaveguideMicrostrip Antenna Arrayreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/7752/1/892213E002049.pdf
