1. A wireless communication device, comprising:
- a first antenna tuned to support a first set of radio frequency bands;
a second antenna tuned to support a second set of radio frequency bands; and
a radio frequency receiver that combines signals detected by the first and second antennas to produce a baseband signal;
wherein the second set of radio frequency bands is different from the first set of radio frequency bands.

Abstract
Systems and methods for improving antenna performance and reducing antenna volume are disclosed herein. In one embodiment, a wireless communication device includes a first antenna, a second antenna, and a radio frequency receiver. The first antenna is tuned to support a first set of radio frequency bands. The second antenna is tuned to support a second set of radio frequency bands. The radio frequency receiver combines signals detected by the first and second antennas to produce a baseband signal. The second set of radio frequency bands is different from the first set of radio frequency bands.

8. A radio module, comprising
a plurality of antennas, each antenna of the plurality of antennas is tuned to cover a different set of frequency bands; - and
an antenna selector coupled to the plurality of antennas; wherein each antenna can serve as a diversity antenna for each other antenna, and the antenna selector switchably couples the plurality of antennas to a receiver based, at least in part, on a selected frequency band. - View Dependent Claims (9, 10)

13. A method, comprising:
-
selecting a frequency band in which a wireless device operates; determining which of a first antenna and a second antenna, each of which can serve as a diversity antenna for the other, is tuned to support the frequency band, when the first antenna supports one set of frequency bands useable by the wireless device, and the second antenna supports a second set of frequency bands useable by the wireless device, and the first set is different than the second set. - View Dependent Claims (14, 15)
