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