| 摘要 |
The invention relates to a multi-frequency band antenna which comprises a first antenna unit for a first frequency band range and at least a second antenna unit for a second frequency band range. The inventive antenna is characterized by the following features: the first antenna (3) and the at least second antenna (9) are nested and integrated into each other; the pertaining dipole halves (3'a, 3''a; 9'a, 9''a) of the at least two antennae (3, 9) are configured in the shape of a pot or box or a similar shape at lea st in terms of their electric equipment; the dipole halves of the at least two antennae (3, 9) are short-circuited (11'a, 11''a) with each other at least a t their adjacent ends (7'a, 7''a) and extend from there at different lengths depending on the frequency band range to be transmitted; and the dipole halv es (3'a, 3''a; 9'a, 9''a) for transmitting the respective lower frequency band range are located within those dipole halves (9'a, 9''a; 25'a, 25''a) that a re provided for the transmission of a respective higher frequency or a respecti ve higher frequency band range. |
