MULTI-BAND RESONATOR ELEMENT FOR MAKING FILTERS, POLARIZERS AND SELECTIVE SURFACES IN FREQUENCIES

摘要

Multi-band resonator element, which on the one hand compensates the components of an electromagnetic field radiated from its phase center located on the axis of symmetry of the resonator to control the polarity purity of a radiating element. On the other hand, it allows selecting the electromagnetic fields reflected and transmitted on a selective surface in frequency and multi-band. In this sense, it is an innovative element that allows the design of directive radiating elements with an axial relationship for circular polarization of less than or equal to 1.5 dB for all angles belonging to the hemisphere centered on "broadside". Likewise, this can be used in the design of reflectarrays, transmitarrays and any multi-band dichroic surface, as well as in metamaterial surfaces.
