▎ 摘　　要

NOVELTY - The antenna has a substrate whose rear surface is arranged with an antenna earth plate. A front face of the substrate is attached with a composite radiation patch that is provided with multiple rhombic photonic crystal small antenna arrays. The rhombic photonic crystal small antenna array is formed with a rectangular hole that is filled with graphene conductive glue. The composite radiation patch is connected with an antenna main body to from a regular hexagon structure. The antenna main body is provided with three rhombic small photonic crystal antennas. The substrate is selected as a low-loss microwave ceramic substrate. The substrate is formed as rectangular-shape in structure. The antenna earth-plate is connected with a bottom edge of the composite radiation patch that is arranged in an antenna feed point. USE - Diamond photonic crystal array composite UWB antenna. ADVANTAGE - The antenna has wide operating band and radiation intensity, low fluctuation rate, high mechanical strength, strong anti- destruction, high stability and reliability in receiving a wireless communication signal, and reduces return loss of the antenna main body. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a diamond photonic crystal array composite Ultra-Wideband (UWB) antenna manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a diamond photonic crystal array composite UWB antenna.
