Abstract : Practical considerations relative to the design and manufacture of microstrip antennas are poorly documented. This report contains practical information on models, substrates. connectors, manufacturing error and feed designs as they relate to microstrip antennas. Two new versions of the transmission line model are introduced and compared to the original version and the model expansion cavity model. Three sets of rectangular patch antennas were constructed on E, = 2.52, 4.4, and 6.0 substrates, respectively, and measured. All models were programmed and compared to these measured results. One new transmission line model achieved less than 0.7 percent resonant frequency error compared to 3 percent error for the original model on the Er = 2.52 substrate. The cavity model also performed well with 1.2 percent and 0.64 percent error for the er = 2.52 and F- = 6.0 substrates, respectively. The er = 4.4 epoxy substrate was deemed unacceptable due to high losses and a poor Er tolerance.
