Dual-band notched ultra-wideband antenna based on double-c structure
By using a dual-C-shaped ultra-wideband antenna with a dielectric substrate, C-shaped radiating patch, and coplanar waveguide ground plane, and by adjusting the size of the tuning slot, the technical problems in the prior art have been solved, including complex structure, unsuitable integration, and inaccurate notch characteristic control. This has resulted in the compactness of the ultra-wideband antenna and its compatibility with wireless local area network systems.
