Problems solved by technology

Ordinary broadband antennas usually cannot effectively transmit and receive ultrashort pulses due to frequency dispersion and spatial dispersion, making them unsuitable for existing ultra-wideband systems
[0003] After searching the literature of the prior art, it is found that ultra-wideband antennas and planar monopoles are two hot spots in the research of modern antenna technology. M.J.Ammann et al. published in February 2003 Microwave and Optical Fiber Technology Journal (Wiley Microwave Opt Technol Letter) The article: A wideband shorted planar monopole with bevel (A wideband shorted planar monopole with bevel), proposed a planar monopole antenna with a short-circuit structure and a cut angle, but the

Abstract

This invention relates to a super-wide band plane single pole antenna including: a radiation element, an earth plate, a coaxial feed port, in which, the radiation element is vertical to the earth plate and connected with the coaxial feed port and composed of a trapezia and a circle with a top, which is inner-tangential with the trapezia to form a smooth transition unit.

Description

technical field [0001] The invention relates to an antenna in the technical field of wireless communication, in particular to an ultra-wideband planar monopole antenna. Background technique [0002] With the rapid development of modern information technology, ultra-wideband technology is being used more and more in many fields such as electronic countermeasures, radar, sonar, and geological exploration. Ultra-wideband technology has the advantages of strong anti-interference ability, high transmission rate, ultra-wide bandwidth, low power consumption, good confidentiality, and low transmission power. UWB antenna is one of the key technologies of UWB. Ordinary broadband antennas usually cannot effectively transmit and receive ultrashort pulses due to frequency dispersion and spatial dispersion, making them unsuitable for existing ultra-wideband systems. [0003] After searching the literature of the prior art, it is found that ultra-wideband antennas and planar monopoles ar...
