摘要： An antenna for circular polarization having an electrical dipole radiator which is oriented essentially parallel to an electrically conductive base surface in a plane of symmetry SE oriented perpendicular to the electrically conductive base surface. The dipole is in connection with a slot radiator which is configured in an electrically conductive base surface, with its longitudinal expanse along the intersection line between the plane of symmetry SE and the electrically conductive base surface. The slot radiator connection location is formed by means of connection points situated at the longitudinal edges and lying opposite one another. The electrical dipole radiator and the slot radiator are tuned to one another in their resonance frequencies. The slot radiator and the electrical dipole radiator with dipole feed line are connected with the antenna connection location by way of a combining network, in terms of magnitude and phase, in such a manner that circular polarization exists in the remote field at the frequency at which the radiators are tuned to one another.

The ring line radiator forms a resonance structure that is electromagnetically excited, whereby the current distribution of a running line wave in a single rotation direction occurs on the ring line. At least one vertical radiator extends toward the conductive base surface and is disposed on the ring line radiator, wherein the vertical radiator is electromagnetically coupled both with the ring line radiator and the electrically conductive base surface, to support the vertically oriented component of the electromagnetic field.

摘要： There is an antenna diversity system for radio reception in moving vehicles which includes a receiver, and at least two antennas coupled to the receiver. These antennas transmit antenna feed signals to an antenna diversity module coupled between the receiver and the antennas. In at least one embodiment, the antenna diversity module comprises at least one evaluation circuit for evaluating an interference in a reception signal, and at least one processor for adjusting a magnitude em and a phase angle of a linear combination of the antenna feed signals. The evaluation circuit reads and sends an interference indication signal to the processor to create a relatively low interference signal. Thus, the diversity module combines the antenna feed signals in an adjustable manner based on an magnitude of phase angle, to form a linear combined signal that is present at the output of the antenna diversity module as a reception signal.

摘要： A reception system for frequency-modulated, i.e. phase-modulated high-frequency signals, for motor vehicles, having a multi-antenna system having at least two antennas, an individually adjustable phase rotation element, situated in the reception path of the corresponding antenna, in each instance, and a subsequent receiver circuit. There is an individually adjustable switching element for switching through or interrupting the signal flow, respectively, is present in the reception path of every antenna. The reception signals are guided by way of phase rotation elements and the adjustable switching elements which are passed to a linear combination circuit, and wherein the combined signal is passed to the receiver circuit. Furthermore, there can be a level indicator for indicating the level of the combined signal in the form of a level signal and a computer device to which this level signal is passed. An the computer device can include an algorithm for determining the phase differences of the reception signals that are present at the input of the combination circuit at a given setting of the phase rotation elements from their level conditions, by means of calculations. This calculation can occur using level measurement samples of the level signal that are performed one after the other, in terms of time, obtained by way of switch setting signals and phase setting signals brought about by the computer device wherein there are differently defined settings of the switching elements or of the phase rotation elements, respectively. Phase setting signals are generated on the basis of the phase differences determined by calculations, for the subsequent setting of the phase rotation elements for phase alignment of the reception signals that are present at the input of the combination circuit when the adjustable switching elements are switched through.
