Abstract

Eine Flachantennenanordnung (Plattenantennenanordnung, Patch-Antennenanordnung) mit einer Masseplatte und einem Strahler, der in einem Abstand im wesentlichen parallel zur Masseplatte angeordnet ist und mit einem seiner Endbereich mit dieser leitend verbunden ist, wobei bei einer ersten (niedrigeren) Resonanzfrequenz der Antennenanordnung an der Verbindung des Strahlers mit der Masseplatte ein Spannungsminimum vorhanden ist und im Bereich des anderen Endes (freies Ende) des Strahlers ein erstes Spannungsmaximum vorhanden ist, ist dadurch gekennzeichnet, dass nahe dem freien Ende des Strahlers (3) ein steuerbares Schalterelement (11) zwischen dem Strahler (3) und der Masseplatte (2) angeordnet ist, das derart ausgebildet ist, dass es eine Verbindung mit niedrigem Widerstand herzustellen in der Lage ist, und dass die Stelle, an der das Schalterelement mit dem Strahler (3) verbunden ist, derart angeordnet ist, dass bei leitend gesteuertem Schalterelement (11) der Strahler (3) eine gegenüber der ersten Resonanzfrequenz höhere, gewünschte zweite Resonanzfrequenz hat. Von Vorteil ist, dass bei beiden Frequenzbereichen der gesamte oder nahezu der gesamte Strahler strahlt.

Figure 00000001
A flat antenna arrangement (plate antenna arrangement, patch antenna arrangement) with a ground plate and a radiator, which is arranged at a distance essentially parallel to the ground plate and is conductively connected to one of its end regions, wherein at a first (lower) resonance frequency of the antenna arrangement at the Connection of the radiator to the ground plate, a voltage minimum is present and a first voltage maximum is present in the area of the other end (free end) of the radiator, characterized in that near the free end of the radiator (3) there is a controllable switch element (11) between the Radiator (3) and the ground plate (2) is arranged, which is designed such that it is able to make a connection with low resistance, and that the point at which the switch element is connected to the radiator (3), such is arranged that when the switch element (11) is controlled, the radiator (3) has a counter has a higher, desired second resonance frequency above the first resonance frequency. It is advantageous that the entire radiator or almost the entire radiator radiates in both frequency ranges.
