Abstract
A microstrip filter having a plurality of parallel resonant conductors mounted on a dielectric substrate is tuned by applying a portion of a hot-melt type glue to the filter surface. The glue is melted and then deposited on the conductors and spread across and along the conductors until the filter has a desired frequency response. The glue is then cooled until it becomes solid.
