A multiresonance antenna useful in small-sized radio devices. In one embodiment, radiating element of the antenna comprises, a first and a second radiating arm of nearly equal electric lengths. The tail portions of the arms are located on different sides of the area determined by the outline of the radiator and point to opposite directions away from each other thereby exciting a double resonance in the antenna. The second arm comprises at least one branch extending towards the tail portion of the first arm thereby widening antenna operating band in the frequency range of 900 MHz. |
