Abstract
An antenna assembly and an electronic device are disclosed. The antenna assembly includes a near-field-communication (NFC) integrated-circuit (IC), a conductive loop, and a radiation-field enhancer. The NFC IC includes a first differential signal port and a second differential signal port for providing a differential excitation current. The first metal stub extends from the first ground portion of the ground plane and electrically connected to the first differential signal port. The conductor is spaced apart from the ground plane, and is electrically connected to the second differential signal port and the second ground portion, respectively. The radiation-field enhancer is disposed between the conductor and the ground plane and configured to enhance a field strength of an NFC radiation-field generated by the conductor in response to the differential excitation current being transmitted.
