Ebene Schlitzantennen und deren Verwendung in Automobilen

摘要

A plane antenna for automobiles including a peripheral conducting surface (10), a first inner conducting surface (11) provided in the peripheral conducting surface with a space (21) in between, a second inner conducting surface (12) provided in the first inner conducting surface with a space (22) in between. A core conductor (31) of a first coaxial line (30) is connected to the first inner conducting surface and an outer skin (32) of the first coaxial line is connected to the peripheral conducting surface, and a core conductor (41) of a second coaxial line (40) is connected to the second inner conducting surface and an outer skin (42) of the second coaxial line is connected to the first inner conducting surface. The second coaxial line can be divided into two sections (40a, 50) so that these sections are inductively connected to each other by coils.
