Abstract
An antenna () for sending and receiving signals in a plurality of frequency bands generates a plurality of resonances in the plurality of frequency bands and includes a first radiating element () that generates a first resonance in a first frequency band, a second radiating element (), coupled to and extending at an angle from the first radiating element (), that generates a second resonance in the first frequency band, and a third radiating element (), coupled to and extended at an angle from the first radiating element (). A capacitive coupling between the second radiating element () and the third radiating element () generates a loop with a third resonance in the first frequency band, and the third radiating element () generates a fourth resonance in a second frequency band independent of the loop at the second frequency band.
