IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. AP-29, NO. 1, JANUARY 1981. A survey of microstrip antenna elements is presented, with emphasis on theoretical and practical design techniques. Available substrate materials are reviewed along with the relation between dielectric constantolerance and resonant freqnency of microstrip patches. Several theoretical analysis techniques are summarized, including transmission-line and modal-expansion (...
