Abstract
A fin-shaped multi-band antenna module, e.g., for vehicles, includes an antenna printed circuit board and a plate arranged thereupon. In a lower region the plate is mechanically connected to the antenna printed circuit board. A first monopole extends in an essentially vertical direction on the plate and is connected to the antenna printed circuit board in a lower region by a feed point. The first monopole is inductively extended in the vertical direction in an upper region of the first monopole in order to enable transmission and reception of electromagnetic waves in a lower telephone frequency range.
Claims18
A fin-shaped multi-band antenna module for a vehicle, the antenna module comprising:
- an antenna printed circuit board,
- a plate connected to the antenna printed circuit board, the plate defining a plane and having a pair of major areas, each extending in both a vertical direction and a horizontal direction,
- wherein, in the vertical direction, the plate has a lower area at a lower end of the plate and an upper area at an upper end of the plate, and
- wherein the lower area of the plate is mechanically connected to the antenna printed circuit board and the upper end of the plate extends away from the antenna printed circuit board,
- a first monopole having a shape of a first arm with a first end and a second end,
- wherein the first monopole extends substantially vertically on at least one of the two major areas of the plate along the plane, and
- wherein the first end of the first monopole is connected via a feed point to the antenna printed circuit board and the second end of the first monopole extends toward the upper end of the plate,
- wherein the first monopole is configured to transmit and receive electromagnetic waves in an upper telephony frequency range between 1710 MHz and 2170 MHz, and
- wherein the first monopole comprises an inductive extension from the second end of the first monopole disposed on the upper area of the plate, the inductive extension comprising a spiral in the plane of the plate, to enable transmission from the antenna printed circuit board through the first monopole and reception from the inductive extension through the first monopole to the antenna printed circuit board of electromagnetic waves in a lower telephony frequency range and a lower LTE frequency range between 792 MHz and 960 MHz.
