## 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

### Claim 1

A diversity antenna system for an automotive vehicle audio system, said diversity antenna system, comprising:
a mirror housing located externally on a first portion of an said automotive vehicle, said housing including a cable exit passage;
a first antenna assembly including at least one antenna element fixedly mounted on a circuit board, wherein the antenna assembly is fixedly located within the externally-located vehicular mirror housing, wherein the cable exit passage passes an antenna cable extending from the circuit board and into the vehicle cabin; and
a second antenna assembly including at least one antenna element fixedly mounted on a circuit board, wherein the second antenna assembly is fixedly located on a second portion of said vehicle, said first and second antenna assemblies operatively coupled to a common signal receiving device, wherein the common signal receiving device is a satellite audio radio receiver disposed within said vehicle cabin.

### Claim 2 (depends on 1)

The antenna system according to claim 1, wherein externally located vehicle mirror housing generally comprises a plastic material.

### Claim 3 (depends on 1)

The antenna system according to claim 1, wherein the at least one antenna element is a dielectric or wire antenna.

### Claim 4 (depends on 1)

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

### Claim 5 (depends on 1)

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

### Claim 6 (depends on 5)

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

### Claim 7 (depends on 5)

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

### Claim 8 (depends on 5)

The antenna system 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.

### Claim 9 (depends on 1)

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

### Claim 10 (depends on 9)

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

### Claim 11 (depends on 9)

The antenna system according to claim 9, wherein the circuit board includes a lip portion positioned adjacent the mirror frame and, said mirror housing defines at least one mounting boss aligned with said lip portion to fixedly retain the circuit board and mirror frame to the mirror housing.

### Claim 12 (depends on 11)

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

### Claim 13 (depends on 1)

The antenna system 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.

### Claim 14

A diversity antenna system for an automotive vehicle audio system, said diversity antenna system comprising:
a first antenna assembly including at least one first antenna element fixedly mounted on a circuit board, wherein the antenna assembly is fixedly disposed within a mirror housing located externally on a first portion of an associated vehicle;
a second antenna assembly including at least one second antenna element fixedly mounted on a circuit board, wherein the second antenna assembly fixedly disposed on a second portion of said vehicle distal said first antenna assembly; and
cable means operatively coupling said first and second antenna assemblies to a common signal receiving device, wherein the common signal receiving device is a satellite audio radio receiver disposed within said vehicle.
