Abstract

A mobile wireless communications device may include a portable housing, a wireless transceiver carried by the portable housing, and a plurality of antennas also carried by the portable housing. Each antenna may have a different gain pattern at a different respective operating frequency, and the antennas may have different shapes to define different gain patterns at a given operating frequency. The mobile wireless communications device may further include a frequency/pattern diversity controller for controlling the wireless transceiver to preferentially operate with the plurality of antennas.

Claims

1. A wireless communications device comprising:

a wireless local area network (WLAN) transceiver;

a plurality of antennas configured to operate at different respective operating frequencies and having different respective gain patterns, each gain pattern being defined by a maximum gain along a common boresight direction; and

a controller configured to cooperate with said WLAN transceiver to preferentially weight received signals from each of said plurality of antennas and to operate said plurality of antennas based upon the preferentially weighted received signals, and said plurality of antennas to preferentially switch said plurality of antennas on and off based upon a given operating frequency.

2. The wireless communications device of claim 1 wherein the different respective gain patterns comprise different gain patterns for different polarizations.

3. The wireless communications device of claim 1 further comprising a housing carrying said WLAN and said controller;

and wherein at least one of said plurality of antennas is carried within said housing.

4. The wireless communications device of claim 1 further comprising a circuit board carrying said WLAN transceiver.

5. A wireless communications device comprising:

a wireless local area network (WLAN) transceiver;

a plurality of antennas configured to transmit and receive at different respective operating frequencies and having different respective gain patterns, each gain pattern being defined by a maximum gain along a common boresight direction; and

a controller configured to cooperate with said WLAN transceiver to preferentially weight received signals from each of said plurality of antennas and to operate said plurality of antennas based upon the preferentially weighted received signals, and said plurality of antennas to preferentially switch said plurality of antennas on and off to transmit based upon a given operating frequency, and to preferentially switch said plurality of antennas on and off to receive based upon a given operating frequency.

6. The wireless communications device of claim 5 wherein the different gain patterns comprise different respective gain patterns for different polarizations.

7. The wireless communications device of claim 5 further comprising a housing carrying said WLAN and said controller;

and wherein at least one of said plurality of antennas is carried within said housing.

8. The wireless communications device of claim 5 further comprising a circuit board carrying said WLAN transceiver.

9. A method for operating a wireless communications device comprising a wireless local area network (WLAN) transceiver, and a plurality of antennas configured to operate at different respective operating frequencies and having different respective gain patterns, each gain pattern being defined by a maximum gain along a common boresight direction;

and

using a controller to cooperate with the WLAN transceiver to preferentially weight received signals from each of said plurality of antennas and to operate said plurality of antennas based upon the preferentially weighted received signals, and the plurality of antennas to preferentially switch the plurality of antennas on and off based upon a given operating frequency.

10. The method of claim 9 wherein the different respective gain patterns comprise different gain patterns for different polarizations.

11. The method of claim 9 wherein the wireless communications device further comprises a housing carrying the WLAN and the controller;

and wherein at least one of the plurality of antennas is carried within the housing.
