Abstract
A method of producing an antenna device for use with a portable radio communication apparatus includes the steps of (i) providing a dielectric substrate, having first and second opposing surfaces; and an ejection apparatus, having a container filled with a liquid conductive substance, an ejection opening in liquid communication with the container, and an implement for ejecting a liquid conductive substance from the opening in the container; (ii) ejecting the liquid electrically conductive substance from the ejecting apparatus, onto the first surface of the dielectric substrate; and (iii) moving the dielectric substrate and the ejection opening relative to each other while ejecting the liquid conductive substance to form, upon being solidified, a conductive antenna pattern on the first surface of the dielectric substrate.
