In this paper, the analysis of patch antennas with U-shaped\ud
metalization loaded by bianisotropic media is deeloped. A theoretical\ud
study is performed to obtain transmission-line equations for bianisotropic\ud
materials, and then a method-of-lines (MoL) procedure is applied to\ud
obtain the radiatie characteristics. Presented results assure, for particular\ud
patch dimensions and feed application geometry, a multifrequency\ud
operation in the microwae range, een for isotropic substrates. The\ud
application of bianisotropic materials gies better performances for bandwidth\ud
and input impedance at the central frequency, but degrades other\ud
frequency operation performances
