K. Guney, A NEW EDGE EXTENSION EXPRESSION FOR THE RESONANT-FREQUENCY OF ELECTRICALLY THICK RECTANGULAR MICROSTRIP ANTENNAS, International journal of electronics, 75(4), 1993, pp. 767-770
A new fringing field extension expression is presented for the resonan
t frequency of electrically thick rectangular microstrip antennas. The
theoretical resonant frequency results obtained by using this new fri
nging field extension expression are in very good agreement with the e
xperimental results available in the literature.
