Antenna for multi-broadband and multi-polarization communication

An antenna for multi-broadband and multi-polarization communication, comprising:

• a plurality of mutually separated radiators connected to a ground plane, the plurality of radiators being configured to jointly function as one or more dipoles;
• each of the plurality of radiators being configured to contribute to resonances at two or more nonoverlapping bands;
• and
• a plurality of conductive parasitic elements, being mutually insulated, and each of the plurality of conductive parasitic elements being insulated from the plurality of radiators and the ground plane;
• wherein:
• on a geometric reference surface, a projection of each of the plurality of conductive parasitic elements extends between two gaps which clamp a projection of an associated one of the plurality of radiators, and does not enclose a geometric origin which is a geometric center of projections of the plurality of radiators.

• a plurality of mutually separated radiators connected to a ground plane, the plurality of radiators being configured to jointly function as one or more dipoles;
• wherein each of the plurality of radiators is configured to contribute to resonances at two or more nonoverlapping bands, and comprises:
• a conductive arm;
• and
• a conductive ground wall connecting the conductive arm and the ground plane;
• wherein the conductive ground wall comprises:
• a meandering portion causing a distance between the conductive arm and the ground plane to be shorter than a length of a current conduction path along the conductive ground wall between the conductive arm and the ground plane;
• a first support wall connecting the conductive arm and the meandering portion;
• and
• a second support wall connecting the meandering portion and the ground plane.
