Abstract

Technologies described herein are directed to switching between antennas in response to a change in an isolation value identified using a neutralization line. A device may include a first set of antennas including a first antenna, a second antenna, a neutralization line coupled between the first antenna and the second antenna, and a controller. The controller is coupled to the neutralization line. The controller determines a first isolation value between the first antenna and the second antenna using the neutralization line, determines a change in isolation value between the first antenna and the second antenna to a second isolation value, determines that the second isolation value exceeds a threshold, and switches from using the first set of antennas to using a second set of antennas.
