摘要： An antenna unit includes an antenna body having a fed radiation electrode and a non-fed radiation electrode that generate a double resonance state and that are mounted on a dielectric substrate, and a substrate for mounting the antenna body thereon. A ground electrode is disposed on the substrate in a predetermined area other than a ground-electrodeless portion provided on the substrate. The ground-electrodeless portion extends from at least one portion of an antenna-body mounting area so as to extend off of and away from the antenna-body mounting area. Grounding ends of the fed radiation electrode and the non-fed radiation electrode are connected to the ground electrode via grounding lines disposed on a predetermined portion of the ground-electrodeless portion, the predetermined portion being outside the antenna-body mounting area.
