1. An antenna apparatus, comprising:
a dielectric substrate;
an antenna coil, disposed on a first surface of the dielectric substrate, and comprising a winding center part, at least one first conductor segment and at least one second conductor segment, the first conductor segment and the second conductor segment being respectively disposed at two opposite sides of the winding center part, the first conductor segment and the second conductor segment being in series connection;
a conductive element, disposed on a second surface of the dielectric substrate opposite to the first surface or disposed in an interior of the dielectric substrate, disposed opposite to the first conductor segment, and electrically connected to the first conductor segment, orthographic projection of the conductive element on the dielectric substrate covering at least one part of orthographic projection of the first conductor segment on the dielectric substrate, a magnetic field generated by the conductive element being configured to cancel out a magnetic field generated by the first conductor segment; and
a first feed portion and a second feed portion disposed on a side of the first conductor segment away from the winding center part; wherein the first feed portion, the conductive element, the first conductor segment, the second conductor segment, and the second feed portion are orderly connected in series.
