1. An antenna comprising a resonance section having an inductance section and a capacitance section connected electrically in parallel;
- whereinthe inductance section has a coil section comprising a conductor formed in a spiral shape circling a coil axis or an angular shape circling the coil axis in a helical form, at least one opening section of opening sections formed at both ends of the coil section is contained in a plane oriented at an angle to the coil axis, and at least one turn of the coil section is substantially contained in a plane oriented at about said angle to the coil axis.

Abstract
An antenna of a compact size enables to raise the inductance value of the resonance section and produce high gain. The antenna is constructed by connecting resonance sections and in series, in which each antenna element has an inductance section and a capacitance section connected electrically in parallel, and each inductance section has a conductor shaped in a square shape to circle the respective coil axes, and the opening sections formed at respective ends of the coil sections are contained in respective planes that are oriented at an angle to the coil axes.
