Abstract
This disclosure provides systems, methods, and apparatus for antenna switching for simultaneous communication. An can include a plurality of antennas including a first antenna and a second antenna. The apparatus can further includes a plurality of receive circuits including a first receive circuit. The apparatus can further include a controller configured to determine one or more performance characteristics of the first antenna at a first time. The controller is further configured to 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. The controller is further configured to selectively switch the first receive circuit from receiving wireless communications via the first antenna to receive wireless communications via the second antenna if the difference is larger than a threshold. Other aspects, embodiments, and features are also claimed and described.
