Abstract:
A dual band antenna for an electronic device, comprising:a ground patch having a connecting portion in a first plane and a bending portion in a second plane, the second plane making a predetermined first angle with the first plane; a first radiating branch extending laterally from the connecting portion for a distance and then extending longitudinally parallel to a longitudinal dimension of the connecting portion; a second radiating branch partly surrounding the first radiating branch and including a connecting patch laterally extending from the connecting portion, and a radiating patch longitudinally extending from the connecting patch, parallel to the longitudinal dimension of the connecting portion, the radiating patch being in a third plane which make a predetermined second angle with a line normal to the first plane; a solder tab protruding from the ground patch; and a coaxial cable feeder having a conductive inner core wire and a conductive outer shield, wherein the inner core wire is electrically connected to the radiating patch and the outer shield is electrically connected to the ground patch by soldering to the solder tab.
