  1. Antenne vom Yagi-Uda-Typ, umfassend ein parasitäres Reflektorelement (310), ein strahlendes Element (320) und mindestens ein parasitäres Direktorelement (330), die in dieser Reihenfolge entlang einer Längsachse der Antenne angeordnet sind, wobei das strahlende Element durch eine leitfähige Platte (321) gebildet wird, die im Wesentlichen rechtwinklig zur Längsachse der Antenne und oberhalb einer Masseebene (310) angeordnet ist, so dass sie einen Monopol bildet, wobei die Platte auf der Seite der Masseebene mit einem Speiseanschluss (322) versehen ist, um ein Antennensignal anzulegen oder zu empfangen, wobei die leitfähige Platte in runder Form vorliegt und an einem zur Masseebene entgegengesetzten Ende mit einer leitfähigen Rückleitung (325) ausgestattet ist, wobei die leitfähige Rückleitung elektrisch mit der Masseebene verbunden ist, so dass die aus der leitfähigen Platte bestehende Einheit und die leitfähige Rückleitung einen gefalteten Monopol bilden, wobei die leitfähige Platte als Scheibe mit einem Durchmesser in der Größenordnung von X/4 vorliegt, worin X eine Wellenlänge ist, die einem unteren Grenzwert eines Betriebsfrequenzbands der Antenne entspricht, und die leitfähige Rückleitung als Stab oder Streifen mit einer Länge vorliegt, die im Wesentlichen identisch mit dem Durchmesser der Scheibe ist.
  2. Antenne vom Yagi-Uda-Typ nach Anspruch 1, bei der sich die leitfähige Rückleitung parallel zu der Scheibe erstreckt und hinter dieser, zwischen der Scheibe und dem parasitären Reflektorelement, gelegen ist.
  3. Antenne vom Yagi-Uda-Typ nach Anspruch 1, bei der sich die leitfähige Rückleitung parallel zu der Scheibe erstreckt und vor dieser, zwischen der Scheibe und dem parasitären Direktorelement, gelegen ist.
  4. Antenne vom Yagi-Uda-Typ nach Anspruch 1, bei der das parasitäre Reflektorelement in der senkrecht zur Masseebene verlaufenden Richtung ein Maß aufweist, das größer als das der leitfähigen Platte entlang derselben Richtung ist.
  5. Antenne vom Yagi-Uda-Typ nach einem der vorhergehenden Ansprüche, bei der das parasitäre Direktorelement als gefalteter Monopol ausgestaltet ist, umfassend ein erstes leitfähiges Segment und ein zweites leitfähiges Segment, die parallel zueinander und zu der leitfähigen Platte sind, wobei die ersten und zweiten leitfähigen Segmente an einem ersten gemeinsamen Ende, auf der zur Masseebene entgegengesetzten Seite, verbunden sind und an ihren zweiten Enden, auf der Seite der Masseebene, nicht verbunden sind.
  6. Antenne vom Yagi-Uda-Typ nach Anspruch 5, bei der die ersten und zweiten leitfähigen Segmente eine Länge haben, die geringer als der Durchmesser dieser Scheibe ist.
  7. Antenne vom Yagi-Uda-Typ nach einem der vorhergehenden Ansprüche, bei der eine Betriebsbandbreite mehr als eine Oktave abdeckt.
  8. Luftfahrzeug mit einer Yagi-Uda-Antenne nach einem der vorhergehenden Ansprüche, wobei die Antenne an einem unteren Teil des Rumpfes des Luftfahrzeugs angebracht ist, wobei die Längsachse der Antenne im Wesentlichen parallel zu einer Längsachse des Luftfahrzeugs ist und wobei die Masseebene durch eine Haut des Rumpfes gebildet wird.
