Surface-mount antenna and communication device with surface-mount antenna

A surface-mounted antenna comprising an approximately rectangular parallelepiped-shaped dielectric base;

• wherein a radiating electrode is formed on an upper face of said dielectric base facing a board mounting bottom face,
• and wherein said radiating electrode comprises an electric-power-supplying-side radiating electrode and a non-electric-power-supplying-side radiating electrode positioned away from said electric-power-supplying-side radiating electrode with a predetermined spacing therebetween, configured so as to resonate based on electric power supplied via a rectifying circuit from an external electric power supplying circuit and to perform transmission and reception of radio waves;
• wherein a shorting portion of said electric-power-supplying-side radiating electrode and a shorting portion of said non-electric-power-supplying-side radiating electrode are positioned on a side face of said dielectric base in close proximity with a predetermined spacing therebetween;
• wherein an open end portion of said electric-power-supplying-side radiating electrode and an open end portion of said non-electric-power-supplying-side radiating electrode are positioned on mutually different sides so as to avoid the face of said dielectric base upon which said shorting portions are formed;
• and
• wherein said rectifying circuit is formed on a side face of said dielectric base.
