Title:
METHOD AND APPARATUS RELATING TO HIGH IMPEDANCE SURFACE
Document Type and Number:
WIPO Patent Application WO2002011239
Kind Code:
A9
Abstract:
A multiple band reconfigurable reflecting antenna array and method for mulitple band operationand beam steering. An array of dipole antennas is disposed on a multiple band high impedancesurface. The antenna array is reconfigured by changing the length of the dipole elements, tothereby change the dipoles resonant frequency. At a given frequency band, small changes in dipole length allow to steer the reflected beam in the selected direction; whether large changes indipole length permit to switch the operating frequency band. A method of broadening thebandwith of a high impedance surface is also exposed.
