Multi-part antenna having a circular polarization |
摘要 |
An antenna device has a first antenna branch and a second antenna branch. Both the first and the second antenna branches have the shape of a non-closed conductor loop and are connected to each other to form a cohesive conductor loop. The respective loop ends are disposed parallel to each other at a distance directed perpendicular (z axis) to the course of the loop. The antenna device has two connections that are disposed in the center section of the cohesive conductor loop at a distance from each other. |

1. An antenna device, comprising:
a first antenna branch formed as a non-closed conductor loop; a second antenna branch formed as a non-closed conductor loop and connected to said first antenna branch such that said second antenna branch continues the conductor loop formed by said first antenna branch and continuing a winding direction thereof; said second antenna branch being disposed at a spacing distance transversely to the winding direction of the conductor loop adjacent to said first antenna branch; a first feed point disposed on said first antenna branch; and a second feed point disposed on said second antenna branch, said second feed point separated from said first feed point by a distance extending in the winding direction of the conductor low; wherein an electrical length of a conductor loop formed by connecting said first antenna branch to said second antenna branch fulfills a resonance condition for an electromagnetic wave to be radiated; wherein said first antenna branch and said second antenna branch form a double inverted F-antenna. |
