Abstract
An antenna device, an electronic apparatus and a method for antenna switching are disclosed by embodiments of the present disclosure. The antenna device includes: a near field communication chip configured to provide a differential excitation current; a ground plane forming a conductive path thereon; a plurality of first conductive assemblies; a first switch configured to selectively be in communication one or more of the first conductive assemblies; a second conductive assembly. The communicating first conductive assembly, the conductive path, and the second conductive assembly together constitute a conductive loop for transmission of the differential excitation current.
