Abstract

Die Antenne für den Empfang zirkular polarisierter Satellitenfunksignale umfasst wenigstens eine mit einem Antennenausgangsanschluss (28) verbundene, zwei-oder dreidimensionale Antennenleiterstruktur (14). Die mehrdimensionale Antennenleiterstruktur (14) ist so gestaltet, dass sie im Wesentlichen aus einer Vielzahl von Antennenleiterabschnitten besteht, die, bezogen auf einen den Antennenleiterabschnitten gemeinsamen Raumbezugspunkt (z), paarweise symmetrisch und in gleicher Richtung sich erstreckend angeordnet sind. Die mehrdimensionale Antennenleiterstruktur (14) ist ferner so ausgebildet, dass bei reziprokem Betrieb der Antenne als Sendeantenne in den einzelnen Paaren von Antennenleiterabschnitten Antennenströme zumindest näherungsweise in gleicher Größe fließen und das arithmetische Mittel der Stromphasen dieser in den Antenneleiterabschnitten jedes Paars jeweils in gleicher Richtung gezählten Antennenströme bei im Wesentlichen sämtlichen Paaren von Antennenleiterabschnitten bezogen auf einen bei reziprokem Betrieb der Antenne als Sendeantenne gemeinsamen Phasenbezugspunkt (B) zumindest näherungsweise den gleichen Wert hat. Eine solche Antenne empfängt gleichermaßen linksdrehend zirkular polarisierte Wellen als auch rechtsdrehend zirkular polarisierte Wellen. Durch einen in dem Phasenbezugspunkt (B) angeordneten vertikalen, elektrisch kurzen Monopol (7), dessen Empfangssignal dem der Antennenleiterstruktur (14) überlagert wird, kann das Vertikalstrahlungsdiagramm zu niedrigen Elevationswinkeln hin aufgefüllt werden.

Figure imgaf001
The antenna for receiving circularly polarized satellite radio signals comprises at least one two- or three-dimensional antenna conductor structure (14) connected to an antenna output terminal (28). The multi-dimensional antenna conductor pattern (14) is designed to substantially consist of a plurality of antenna conductor portions arranged in pairs symmetrically and in the same direction extending with respect to a spatial reference point (z) common to the antenna conductor portions. The multi-dimensional antenna conductor structure (14) is further configured such that when the antenna is reciprocally operated as the transmitting antenna in the individual pairs of antenna conductor sections, antenna currents flow at least approximately equal in magnitude and the arithmetic mean of the current phases of these antenna currents counted in the same direction in the antenna conductor sections of each pair in substantially all of the pairs of antenna conductor sections, with respect to a common phase reference point (B) common to reciprocating operation of the antenna as the transmitting antenna, at least approximately the same value. Such an antenna equally receives levorotatory circularly polarized waves as well as right handed circularly polarized waves. By means of a vertical, electrically short monopole (7) arranged in the phase reference point (B), whose received signal is superimposed on that of the antenna conductor structure (14), the vertical radiation pattern can be filled up to low elevation angles.
