Abstract
An antenna structure having a ground plane, a feed line and at least one resonator element that is embedded in a dielectric substrate and which is meandering in shape such that it includes at least two adjacent resonator segments. As a result, the resonator element resonates in two separate frequency bands. A second resonator element is provided, the second resonator element being dimensioned to resonate in a frequency band below a third operating frequency band, the feed line and ground plane being arranged to cause a resonance in a frequency band located above the third operating frequency band. During use, the combined effect of the resonance of the second resonator element and of the feed line and ground plane is to cause the antenna structure to resonate in the third operating frequency band.
