Abstract
An electronic communication device performs a method to detect proximity of an object to the device. The method includes determining a set of mutual coupling values for at least one pair of a plurality of antennas arrays of the electronic communication device. Each mutual coupling value indicates an efficiency of a mutual coupling transmission between an antenna element of a first antenna array of a pair of antenna arrays and an antenna element of a second antenna array of the pair of antenna arrays. The method further includes determining object position relative to the plurality of antenna arrays based on the set of mutual coupling values.
