Abstract: A rod antenna and a method for operating the rod antenna. The rod antenna includes a two-dimensional patch for radiating and/or receiving an electromagnetic wave, the patch extending along a plane defined by two coordinate axes orthogonal to each other. A feeding line is coupled to the patch for transferring signal energy to and/or from the patch, and a dielectric rod radiates and/or receives the electromagnetic wave, the rod extending longitudinally from the patch in direction of a third coordinate axis outside of the plane defined by the first two coordinate axes. A metal holder is coupled to the patch and to the rod for transferring the electromagnetic wave between the patch and the rod.

Abstract: The present invention provides a short-range wireless mobile communication system with a first terminal and a mobile terminal that are each adapted for transmitting and receiving an information carrying signal wave, whereby at least the first terminal or the mobile terminal comprise a directional signal wave converter for transmitting and/or receiving the information carrying signal wave with a directional characteristic and a control means for controlling the directional characteristic according to a position of the mobile terminal relative to the first terminal.

Abstract: The present invention provides a short-range wireless mobile communication system with a first terminal (1) and a mobile terminal (2) that are each adapted for transmitting and receiving an information carrying signal wave, whereby at least the first terminal (1) or the mobile terminal (2) comprise a directional signal wave converter (1a) for transmitting and/or receiving the information carrying signal wave with a directional characteristic (1bI, 1bII) and a control means (4, 5, 20) for controlling the directional characteristic (1bI, 1bII) according to a position of the mobile terminal (2) relative to the first terminal.
