Abstract

A second antenna supplementing the main antenna of a small-sized radio device. The second antenna (300) has operating bands for implementing the space diversity in the receiving in accordance with two radio systems. The radiators (310, 320) corresponding to these operating bands are for the most part of conductive coating of a chip substrate (340) on the circuit board (PCB) of the radio device so that their directions on the substrate surface are opposite as viewed from the feed points (315, 325) of the radiators. In addition, the second antenna comprises a third radiator (330) at the substrate on the opposite surface of the circuit board for the GPS reception. The multiband second antenna is very small-sized.
