A conformal array antenna includes a substrate and a conductive circuit. The substrate has a non-conductive roughened curved surface formed with a plurality of hook-shaped structures that are formed by blasting a plurality of particles on the substrate. The non-conductive roughened curved surface defines a plurality of spaced-apart antenna pattern regions. The conductive circuit is located in the antenna pattern regions, and includes an activation layer formed on the roughened curved surface and containing an active metal, and a first metal layer formed on the activation layer.

Conformal array antenna

A method for making a conformal array antenna includes: providing a substrate having a non-conductive curved surface; roughening the curved surface; forming an activation layer containing an active metal on the roughened curved surface; forming a first metal layer on the activation layer by chemical plating process; and defining a plurality of spaced-apart antenna pattern regions on the first metal layer, by forming a gap along an outer periphery of each of the antenna pattern regions to isolate the antenna pattern regions from a remainder of the first metal layer. The curved surface is roughened by blasting a plurality of particles thereonto, or the spaced-apart antenna pattern regions are substantially evenly distributed.
