Abstract
A rectangular microstrip antenna fed by a coplanar waveguide with an i nductive or a capacitive coupling end slot is analyzed by using the mo ment method. Numerical calculations for the input impedances are shown to agree well with those of the measurements. For the purpose of desi gn, a parameter study for the variations of input impedance with lengt h and width of the coupling slot is presented. Differences in the inpu t impedance characteristics between the inductive and capacitive coupl ing cases are also discussed.
