MICROSTRIP TRANSMISSION LINE APPARATUS HAVING WIDE BAND PLANAR FILTER

摘要

PURPOSE: A microstrip transmission line apparatus with a broadband planar filter is provided to increase bandwidth for passing or cutting off a specific frequency to broadband by integrating multiple frequency selective surface unit cells on a microstrip transmission line. CONSTITUTION: A dielectric substrate(11) has a ground patter in the rear side. A microstrip transmission line(13) is formed on the top of the dielectric substrate and transmits transmission signals. Frequency selective surface unit cells are inserted in the microstrip transmission line and pass or cut off the transmission signals of specific frequencies.
