Passage from an inset-fed rectangular patch antenna to an end-fed and probe-fed rectangular patch antenna, modelling and analyses

This communication describes a passage possibility from an inset-feed rectangular patch antenna to an end-fed and probe-fed rectangular patch antenna. It will make, while acting on the following parameters: the width of the microstrip feed, gap between microstrip feed and patch, and feed-line inset distance. The dependence of the input resistance on feed position of probe-fed antenna is also between these parameters. One will describe a modelisation, analysis of this antenna input impedance, simulation of the results by the MATLAB software and comparison with the PCAAD software (personal computer aided antenna design).
