Antenna device for thinning and miniaturization of radio communication equipment, has substrate body with insulating properties, where ground planes are patterned and formed on surface of substrate body using metal foils

摘要

The antenna device has a substrate body with insulating properties, where ground planes (GND) are patterned and formed on the surface of the substrate body using metal foils. An antenna pattern is patterned and formed on the surface of the substrate body using the metal foil, and extends by providing a power supply point on a proximal end of the ground panel-side. A single-sided antenna element (AT1) of a dielectric antenna is provided on either a front surface or rear surface of the substrate body, and is connected with a distal end of the antenna pattern.
