Antenna device, especially for mobile communication instrument

摘要

The antenna device comprises a first helical antenna (1) and a second helical antenna (2) connected with each other, and a pull-out rod antenna (3). A connecting element (7) is provided, which connects only the rod antenna with the first helical antenna in the extended condition of the rod antenna, and which connects the second helical antenna with the first helical antenna, when the rod antenna is pushed in. The first helical antenna, the second helical antenna as well as the rod antenna (3) are preferably adjusted to a quarter of the wavelength of the frequency range to be transmitted or received.
