Abstract:

A collection of design formulas for circular and rectangular microstrip antennas excited in the lowest resonance mode are presented. The elements are modeled as cylindrical resonators with equivalent magnetic currents around the perimeters. Fringing fields represent extensions of the elements and have been considered when resonance dimensions are determined. The Q-factors are usually high, making the instantaneous bandwidths narrow. A two-section feed network has been used to simultaneously match the elements at two frequencies separated or - 12 percent. Both a circular and a square microstrip radiator have been designed and fabricated. The radiation from the feed lines was suppressed by designing them in stripline. An extensive bibliography of microstrip antenna work is included. Author
