ABSTRACT:
An antenna for use in a portable electronic communication apparatus has a pattern of a conductive material. The pattern of conductive material is printed on the Printed Circuit Board (PCB) (7), comprising the RF circuitry of the portable electronic communication apparatus, to which antenna pattern is connected. The pattern comprises a first and second antenna arm, which together for a PIFA antenna and are resonating in a first and second frequency band, respectively. As an alternative, the antenna pattern forms a multi-port antenna having separate antenna arms for Rx and Tx, respectively.
