Abstract

An antenna assembly is disclosed. The antenna assembly includes an externally-located vehicular mirror housing and an antenna assembly. The externally-located vehicular mirror housing includes a cable exit passage. The antenna assembly includes at least one antenna element mounted on a circuit board. The antenna assembly is located within the externally-located vehicular mirror housing. The cable exit passage passes an antenna cable extending from the circuit board and into the vehicle cabin.

Claims

1. An antenna assembly, comprising:

an externally-located vehicular minor housing including a cable exit passage; and

an antenna assembly including at least one antenna element mounted on a circuit board, wherein the antenna assembly is located within the externally-located vehicular mirror housing, wherein the cable exit passage passes an antenna cable extending from the circuit board and into a vehicle cabin; and

wherein the circuit board includes a lip portion extending therefrom to retain the circuit board to the mirror housing.

2. The antenna assembly according to claim 1, wherein the externally-located vehicular mirror housing generally comprises a plastic material.

3. The antenna assembly according to claim 1, wherein the at least one antenna element is a wire antenna.

4. The antenna assembly according to claim 1 further comprising a low noise amplifier located inside the circuit board.

5. The antenna assembly according to claim 1, wherein the at least one antenna element is a patch antenna element.

6. The antenna assembly according to claim 5, wherein the patch antenna receives SDARS frequencies.

7. The antenna assembly according to claim 5, wherein the patch antenna receives GPS frequencies.

8. The antenna assembly according to claim 5, wherein a complementary pair of patch antennas are each located in driver- and passenger-side vehicular mirror housings so as to operate as part of a diversity antenna application to provide uninterrupted reception of the satellite signals.

9. The antenna assembly according to claim 1, wherein the mirror housing further comprising at least one mounting boss that retains a mirror frame.

10. The antenna assembly according to claim 9, wherein the mirror frame comprises a circuit board retaining portion that maintains the circuit board at an elevation angle.

11. The antenna assembly according to claim 1, wherein the lip portion is perpendicular to the circuit board and positioned about the mirror frame and at least one mounting boss to retain the circuit board to the mirror housing.

12. The antenna assembly according to claim 11, receives and transmits PCS/AMPS, RKE, TPM, and AM/FM frequencies.

13. The antenna assembly according to claim 1, wherein the at least one antenna element is selected from the group consisting of a normal mode helical antenna, an inductively loaded monopole antenna, a loop antenna, and a microstripline antenna printed on a circuit board.
