Abstract

Eine Antenne ist durch ein bogenförmig über einer Grundplatte (1) angeordnetes Resonanzelement (2) gebildet. Das streifenförmige Resonanzelement (2), welches als λ/4-Resonator arbeitet, ist an einem Ende durch ein Kurzschlusselement (3) mit der Grundplatte (1) verbunden. Das Kurzschlusselement (3) steht schräg zur Grundplatte (1). Das gegenüberliegende Ende (4) des Resonanzelements (2) hat einen bestimmten Abstand (A) zur Grundplatte (1).

Figure 00000001
An antenna is formed by a resonance element (2) arranged in an arc shape above a base plate (1). The strip-shaped resonance element (2), which works as a λ / 4 resonator, is connected at one end to the base plate (1) by a short-circuit element (3). The short-circuit element (3) is at an angle to the base plate (1). The opposite end (4) of the resonance element (2) has a certain distance (A) to the base plate (1).
