The phase center is studied for Fabry-Pérot cavity antennas viewed as two-dimensional leaky-wave radiators, adopting both local and global definitions. Closed-form expressions are obtained for the phase-center location of broadside pencil beams, as a function of the attenuation constant of the leaky mode responsible for radiation and of the extension of the angular sector of interest. Numerical results that validate the proposed formulas are given for specific antenna structures.

Abstract
The phase center is studied for Fabry-Pérot cavity antennas viewed as two-dimensional leaky-wave radiators, adopting both local and global definitions. Closed-form expressions are obtained for the phase-center location of broadside pencil beams, as a function of the attenuation constant of the leaky mode responsible for radiation and of the extension of the angular sector of interest. Numerical results that validate the proposed formulas are given for specific antenna structures.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
