An antenna arrangement for dual mode radio devices such as WCDMA/GSM or Bluetooth radio devices. The arrangement contains two antennas close to each other, where a shorting switch is used at an open end of one antenna to increase isolation by effectively converting the one antenna from a quarter wave length antenna to a half wave length antenna when not needed in order to improve the efficiency of the other antenna. The shorting switch is typically a MEMS switch and the antennas are typically PIFA antennas. A radio device containing the arrangement has also been disclosed.

Mobile communication

A method of forming a unitary housing element of an apparatus and incorporating an antenna is incorporated into the unitary housing element. The method includes the steps of printing onto a first surface of a carrier film, using conductive ink, the antenna, inserting the carrier film into a mold, and forming the unitary housing element by injecting a molding material onto the mold, thereby incorporating the antenna into the unitary housing element.
