ABSTRACT:
An antenna operative in a plurality of frequency bands. The antenna comprises first and second high band resonators, a resonating meanderline and a counterpoise. A ground return conductively couples one or more regions of the counterpoise to the meanderline. One or more of the first resonating element, the second resonating element and the resonating meanderline are coupled by magnetic and/or capacitive coupling to provide operation in the plurality of frequency bands.
