Abstract
Two methods of controlling the input impedance of a microstrip end-fed patch antenna are investigated. Using a 4 GHz reference antenna, the variations of input impedance and radiation patterns are compared, for (a) changing the feed positions to the non-radiating edge against (b) changing the width of a normal fed patch antenna. An expression for finding the necessary width for the last case is given using the results of the analysis.
