Antenna with substrate and conducting track has at least one aperture formed by hollow chamber enclosed by substrate or by recess formed in one or more surfaces of substrate

摘要

The device has an electrical or permeable substrate (10) and at least one resonant conducting track structure. The substrate has at least one aperture (30) formed by a hollow chamber enclosed by the substrate or by a recess formed in one or more surfaces of the substrate. The recess forms a channel extending along a length of the substrate. Independent claims are also included for the following: a printed circuit board and a mobile telecommunications device with an inventive antenna.
