Ky. Sze et L. Shafai, Formulation for reflection coefficient phase of infinite periodic array ofmicrostrip patches, ELECTR LETT, 37(3), 2001, pp. 142-143
For the analysis of an infinite periodic array of single-layer rectangular
microstrip patches, an empirical expression is formulated for approximating
the TE-to-z reflection coefficient phase with the incident angle. The accu
racy of the results from this empirical formulation is verified with those
computed through the: full wave analysis.
