Transmission line model design formula for microstrip antennas with slots

Abstract

A technique, based on the transmission line model, for the analysis of a rectangular microstrip antenna, in which more than one slot have been embedded in its non-radiating edges, is presented. Using this method, the number and the dimensions of the slots in a microstrip antenna can be calculated, in order to get a desired lower resonant frequency from a much smaller patch than the initial rectangular one.
