摘要:
An antenna apparatus has a first antenna branch and a second antenna branch. Both the first and the second antenna branch are in the form of a conductor loop which is not closed, and the first antenna branch is arranged at a distance from the second antenna branch in a direction which is substantially at right angles to the surface bounded by the respective conductor loop, such that the first loop direction, which is defined from the foot point to the free end of the first antenna branch, is arranged in the opposite direction to the second loop direction, which is defined from the foot point to the free end of the second antenna branch.

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.

A transmission arrangement for a radio station of an access system may include a printed circuit board with an upper main surface and a first metallisation plane in which conducting paths are formed. A drive circuit for supplying a frequency signal and an antenna structure are also provided. The antenna structure includes a coupling device, a conductor structure and a continuous, electrically conductive path having first and second ends opposite each other. The coupling device is configured to couple a frequency signal supplied by the drive circuit into the conductor structure. The first and/or second ends form end(s) of the conductor structure. The printed circuit board is retained at a distance from the first and/or second end by a gas or an electrically non-conductive material.

A multiband shark fin antenna for a vehicle may include at least one transmitting and one receiving antenna element from the group consisting of AM/FM antennas, telephone and RKE antennas, GPS antenna, SDARS antenna, stacked patch antenna, DAP antenna, WLAN antenna, WIMAX antenna or DRM antenna. The antenna elements are disposed beneath a joint shark fin-shaped outer cover on the exterior of the vehicle. On the inside, the shark fin-shaped outer cover includes an antenna circuit board having the antenna elements disposed thereon. Electronic adjustment or amplifier circuits including a transceiver, tuner or receiver are disposed on both the upper and lower faces of the antenna circuit board. Shielding plates, which shield the adjustment or amplifier circuits with respect to the antenna elements, are disposed on the upper side of the antenna circuit board.

摘要:
An antenna structure for a vehicle may include an electrically conductive structure arranged on two insulating substrate plates that are arranged perpendicularly to each other and intersect each other. A dipole is provided on each electrically conductive structure. The dipoles form a first U-shaped dipole structure on each of the two substrate plates. On an upper edge region of each of the substrate plates, the dipole structure has a line element, and on the lateral regions of the substrate plate, the dipole structure has electrically conductive limbs. The electrically conductive structure has a monopole arranged asymmetrically to the dipole structure for respectively feeding the dipole.
