An antenna 10 includes a base print layer 2 printed in a predetermined antenna pattern on a surface of a workpiece 1, and an electroless plating layer 3 disposed on the surface of the base print layer 2. The base print layer 2 is formed of an ink 2a and metal particles 2b. The ink 2a has been printed with a substantially uniform thickness to form an ink layer, in which some of particles of the metal particles 2b are buried. The metal particles having a large diameter are partially protrudent from the ink layer, and part of the ink 2a covering the protrudent portions have been removed.

Printing method to print one or more print tracks on a print support, or substrate, comprising two or more printing steps in each of which, by means of printing means, a layer of material is deposited on the print support according to a predetermined print profile. In each printing step, subsequent to the first, each layer of material is deposited at least partially on top of the layer of material printed in the preceding printing step, so that each layer of printed material has an identical print profile or different with respect to at least a layer of material underneath so as to achieve an area of contact equal to or different from at least an area previously printed, the material deposited in each printing step being equal to or different from the material deposited in at least one of the prints underneath.

A circuit pattern forming method is provided which can reduce a possibility of undesired short-circuits being produced in the circuit by satellites formed when fabricating a conductive pattern and thereby can form a highly reliable printed circuit board. To that end, this invention overlappingly draws a conductive pattern (11) and an insulating pattern (13) of a predetermined thickness by scanning a liquid ejection head and a substrate (10) relative to each other a plurality of times while ejecting droplets of a conductive pattern forming solution (11) and an insulating pattern forming solution (13). When forming the conductive pattern and the insulating pattern that adjoin each other on the substrate, the step of forming the insulating pattern of at least one scan is executed between the conductive pattern forming steps that are executed the plurality of times until the conductive pattern has a predetermined thickness.
