First Claim
1. A wireless communication apparatus, comprising:
- a plurality of antennas including a first antenna and a second antenna;
a plurality of receive circuits including a first receive circuit; and
a controller configured to;
determine one or more performance characteristics of the first antenna at a first time;
determine a difference between the one or more performance characteristics of the first antenna at the first time and one or more performance characteristics of the first antenna at an earlier time, wherein determining a difference comprises determining a persistent drop between a first value corresponding to a plurality of performance characteristics of the first antenna determined at the first time and a second value corresponding to a plurality of performance characteristics of the first antenna determined at an earlier time; and
selectively switch the first receive circuit from receiving wireless communications via the first antenna to receive wireless communications via the second antenna if the determined difference is larger than a threshold,wherein the one or more performance characteristics of the first antenna at the first time comprise a first plurality of performance characteristics, and wherein the one or more performance characteristics of the first antenna at the earlier time comprise a second plurality of performance characteristics, andwherein the determining a persistent drop comprises determining a drop in each of the first plurality of performance characteristics relative to each of the second plurality of performance characteristics.
