Abstract
Briefly, in accordance with an embodiment of the invention, an apparatus and method to provide antenna diversity to reduce multipath effects is provided. The apparatus may include a primary antenna and a secondary antenna, wherein the antenna gain of the secondary antenna is greater than the antenna gain of the primary antenna. The method may include selectively switching between either a primary antenna or a diversity antenna to receive signals, wherein a gain of the primary antenna is less than a gain of the diversity antenna.
Claims23
An apparatus, comprising:
- a primary antenna having a gain;
- and
- a secondary antenna having a gain greater than the gain of the primary antenna, wherein the gain of the secondary antenna is at least about 6 dBi;
- wherein the primary antenna is a transmit and receive antenna and the secondary antenna is a receive only antenna.
An apparatus, comprising:
- a first antenna to transmit and receive signals;
- and
- a second antenna to only receive signals and having a gain greater than a gain of the first antenna, wherein the second antenna is separate from the first antenna.
A system, comprising:
- a wireless local area network (WLAN) device comprising:
- a primary antenna having a gain;
- and
- a secondary antenna having a gain greater than the gain of the primary antenna, wherein the secondary antenna has a gain of at least about 6 dBi;
- wherein the primary antenna is a transmit and receive antenna and the secondary antenna is a receive only antenna.
A method, comprising:
- receiving a first signal from a transmit and receive antenna;
- and
- receiving a second signal from a receive only antenna, wherein the receive only antenna has a gain greater than a gain of the transmit and receive antenna and wherein the receive only antenna is separate from the transmit and receive antenna.
A method, comprising:
- selectively switching between either a primary antenna or a diversity antenna to receive signals, wherein a gain of the primary antenna is less than a gain of the diversity antenna and the diversity antenna is discrete from the primary antenna.
