Abstract:
An antenna, comprising:a front panel having a conductive layer with at least a first slot and a second slot, and a signal conductor with at least a first and second conductive section, the signal conductor being separated from the conductive layer by a nonconductor, the first conductive section extending over the first slot and the second conductive section extending over the second slot;a conductive rear panel substantially parallel to the front panel, the conductive rear panel being electrically connected to the conductive layer;a first electric field barrier positioned between the first and second slots and extending between the front panel and the rear panel, the electric field barrier being in electrical contact with the front panel and the rear panel and being substantially parallel to a long slot edge;a second electric field barrier positioned outside an outer edge of the first slot and extending between the front panel and the rear panel, the second electric field barrier being in electrical contact with the front panel and the rear panel and being substantially parallel to a long slot edge; anda third electric field barrier positioned outside an outer edge of the second slot and extending between the front panel and the rear panel, the third electric field barrier being in electrical contact with the front panel and the rear panel and being substantially parallel to a long slot edge.
