CONTACT ARRANGEMENT FOR A PLANAR ANTENNA

摘要

An arrangement for coupling separate spring contacts to the radiating plane of the antenna of a radio device. As a radiator (320) of the antenna is used a conductor foil, which is fastened on the upper surface of the dielectric frame (350) of the antenna. The feed and short-circuit of the radiator are preferably arranged by means of pogo pins (330), which are pushed down into the holes in the frame before the fastening of the radiator. Each hole is shaped, regarding its height and inner surface such that the pin remains steadily in the hole with its upper end towards the radiator. The reliability of the galvanic contact is improved by a dielectric assuring element (360), which is pressed against the radiator from above. The assuring element is mechanically locked in place. The frame with the attached parts is installed in place above the circuit board of the radio device, whereupon the lower ends of the pogo pins are coupled by spring force galvanically against the contact surfaces on the circuit board.
