ABSTRACT:
The present invention relates generally to a new family of antennas with a multiband behaviour and a reduced size. The general configuration of the antenna consists of a multilevel structure which provides the multiband behaviour, combined with a multilevel and/or space-filling ground-plane. The multilevel structure consists of two arms of different length that follow a winding parallel path spaced by a winding parallel gap (parallel to the arms) with a substantially similar shape as each of said arms, that is, with a similar winding path as the arms. The resulting antenna covers the major current and future wireless services, opening this way a wide range of possibilities in the design of universal, multi-purpose, wireless terminals and devices.
