Classification: CPC H | IPC H

Claim 14:
15. A method of fabricating an antenna element, the method comprising:
using a proto laser machine to fabricate a feeding source, a driven patch, and a parasitic patch on a substrate, the feeding source comprising two through holes extending therethrough; and
performing extrusion plating with a metal material to form two vias in the two through holes, respectively;
the driven patch being electrically connected to the feeding source,
the parasitic patch being physically separated from the driven patch by a first gap,
the feeding source comprising a coplanar waveguide (CPW) including a first source patch, a second source patch, and a microstrip feedline disposed between the first source patch and the second source patch,
the driven patch comprising a main patch and an inset feedline extending in a first direction from the main patch towards the feeding source,
a length of the parasitic patch, taken in the first direction, being smaller than a length of the driven patch, taken in the first direction, and
the driven patch being disposed between, in the first direction, the feeding source and the parasitic patch;
wherein the antenna element is a dual-band antenna element for operation at a first frequency of 78 gigahertz (GHz) and a second frequency of 94 GHz.
