Highly integrated multiband shark fin antenna for a vehicle

摘要

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.

主权项

1. A multiband shark fin antenna comprising:
a common shark-fin-shaped outer cover defining an interior; a system arranged in the interior of the shark-fin-shaped outer cover, comprising:
an antenna circuit board having a top side and an underside;antenna elements including at least one transmitting antenna element and at least one receiving antenna element, the antenna elements being arranged on the top side of the antenna circuit board,a plurality of electronic circuits comprising at least one of matching circuits or amplifier circuits that include at least one of transceivers, tuners, or receivers, wherein at least one of the electronic circuits is arranged on the top side of the antenna circuit board and at least one other of the electronic circuits is arranged on the underside of the antenna circuit board, andat least one shielding plate arranged on the top side of the antenna circuit board and configured to shield the at least one electronic circuit arranged on the top side of the antenna circuit board from the antenna elements arranged on the top side of the circuit board, wherein the antenna circuit board comprises a conductive track extending around one or more electronic devices of the at least one electronic circuit arranged on the top side of the antenna circuit board, the conductive track being connected to ground; and wherein the at least one shielding plate includes a first shielding plate having a plate portion and a perimeter wall extending around a perimeter of the plate portion, wherein the first shielding plate is mounted to the antenna circuit board with the perimeter wall of the first shielding plate mounted to the conductive track, to thereby electrically ground the first shielding plate and to enclose the one or more electronic devices between the first shielding plate and antenna circuit board.
