Abstract:
1. An antenna assembly comprising: a base board made from a dielectric material, and having upper and lower surfaces, each of which defines a grounding domain and a dielectric domain, said base board further having a first metal layer disposed on said grounding domain of said lower surface and a second metal layer disposed on said grounding domain of said upper surface; an antenna unit fabricated on said dielectric domain of said upper surface of said base board, and including an antenna body and a feeding line; and a plurality of conductive through holes formed through said base board for connecting electrically said first and second metal layers, thereby permitting coupled current flow generated in said second metal layer to flow into said first metal layer; a first slot of predetermined length formed through said first metal layer for enhancing effective coupled current flowing into said first metal layer, thereby increasing transmitting and receiving ability of said antenna unit.
