Antenna circuit arrangement and testing method

A portable radio device comprising an antenna arrangement, further comprising:

• a planar antenna with a ground plane and a planar radiator element and disposed substantially parallel to the ground plane, and
• an RF circuit coupled to the planar antenna for processing RF signals received by the planar antenna and/or RF signals to be transmitted by the antenna,
• characterized in that
• the antenna circuit arrangement comprises a test point for connecting a test signal to/from the RF circuit, and
• an aperture in the planar radiator element for conveying said test signal through said aperture.

A method for assembling and testing an antenna arrangement including a planar antenna and RF electronics, the planar antenna comprising a ground plane and a planar radiator which is substantially parallel with the ground plane, wherein

• the RF electronics is assembled,
• the planar radiator is attached to the RF electronics assembly,
• the RF electronics is tested by connecting a test signal to/from the RF-electronics which is decoupled from the planar antenna,
• the planar planar antenna is coupled to the RF electronics, and
• the planar antenna is tested when the planar antenna is coupled to the RF electronics,
• characterized in that
• in said step of testing the RF electronics a test signal is conveyed through an aperture of the radiator plane of the planar antenna to/from a test point of the RF electronics.
