Absfruct-A surveyofmicrostripantennaelementsispresented, with emphasis on theoretical and practical design techniques. Availablesubstratematerialsarereviewedalong with the relation between dielectric constant tolerance and resonant freqnency of microstrip patches. Several theoretical analysis techniques are summarized, including transmission-line and modal-expansion (cavity) techniques as well as numerical methods such as the method of moments and fmite-element techniques. Practical procedures are given for both standard rectangular and circular patches, as well as variations on those designs including circularly p
