Embodiments of this application provide an antenna apparatus and an electronic device. The antenna apparatus is provided with a non-resonant unit and a feed unit, to respectively feed a radiation unit and a non-resonant unit. Through feeding power distribution design, the non-resonant unit can assist in exciting a floor characteristic mode. In addition, since a size of the non-resonant unit is much smaller than an electrical length required for resonance of an antenna on this frequency band, the non-resonant unit does not generate a resonance curve on a resonance curve and has no resonance point, to improve radiation efficiency of the antenna without generating new resonance, so as to improve a use effect of a user.
