Abstract
Double-resonance characteristics are obtained with a small and simple construction by arranging a conductive planar radiation element approximately parallel to a conductive ground plane with an intermediary insulator, connecting a feed line to these, and further connecting a parasitic line to a separate contact point at a distance from the contact point of the feed line.
