Embodiment 1

[0018] The planar ultra-broadband antenna of this embodiment can refer to the structural schematic diagram that Fig. 1 provides and the side view that Fig. 2 provides, the rear view that Fig. 3 provides and the top view that Fig. 4 provides: it is made of dielectric substrate 1, and is printed on respectively The radiation copper layer 2 and the feed copper layer 3 on both sides of the dielectric substrate are composed of three parts.

[0019] The dielectric substrate 1 has a certain dielectric constant and thickness, and its functions are: firstly, to transmit energy in the feeding transmission line, and secondly, to support the radiation copper layer and the feeding copper layer. In order to reduce the influence of the dielectric plate on the field distribution at the coupling structure, a dielectric substrate with a lower dielectric constant is usually used, and a thinner thickness is selected under the condition of ensuring a certain hardness. In this implementation exampl...

Description

Technical field: [0001] The invention belongs to the technical field of ultra-wideband antennas, in particular to planar omnidirectional radiation antennas. Background technique: [0002] As a key component for radiating and receiving energy in an Ultra-Wide Band (UWB) wireless communication system, the antenna has performance requirements including a large impedance bandwidth, small size and easy conformability, and low processing cost. [0003] The International Institute of Electrical and Electronics Engineers "Antennas and Propagation" magazine (IEEE Transaction on Antennas and Propagation, No. 2, 1998, pages 294-295) once introduced the elliptical monopole antenna as a typical structure for obtaining a large impedance bandwidth, but due to this type In actual application, the antenna needs a large ground plane perpendicular to the radiation sheet, so that on the one hand, this type of antenna only has energy radiation in the upper half space containing the radiation uni...
