Abstract
An internal antenna especially aimed at flat radio devices. The antenna () comprises a planar radiator () with a branch () for forming a lower operating band for the antenna and a second branch () for forming an upper operating band. The branches typically form a frame-like pattern. There remains a slot () between the branches, opening to the outer edge of the radiator approximately in the middle of the edge running in the direction of the end of the circuit board () and being outside the circuit board as seen from above. The omnidirectional radiation of the antenna on its upper operating band improves as compared to the corresponding, known antennas, and its efficiency improves, because the average antenna gain increases.
