Abstract:
1. A method of producing an antenna device for use in a portable radio communication apparatus, said method comprising the steps of: providing a dielectric substrate having a first and a second surface opposite to each other; said first surface of said dielectric substrate being essentially non-planar; providing an ejecting apparatus that is adapted to form antenna patters on said dielectric substrate; ejecting a liqyid electrically conductive substance from said ejecting apparatus onto the first surface of said dielectric substrate, said ejecting apparatus having a container filled with said liquid conductive substance, an ejection opening in liquid communication with said container, and an implement for ejecting liquid conductive substance from said container through said opening; and moving said dielectric substrate and said ejection opening relative each other while ejecting said liquid conductive substance to thereby form, upon being solidified, a conductive antenna pattern on the first surface of said dielectric substrate.
