Abstract
The invention discloses a miniature high performance antenna, comprising copper pipes and a coaxial cable. A filling is filled between each copper pipe and the coaxial cable as a dielectric medium; the center of the filling is provided with a hole, through which the coaxial cable penetrates. Traditional antennas all employ air as a dielectric medium, and fillings do not exist between a copper pipe and a coaxial cable. In the invention, a filling is filled between each copper pipe and the coaxial cable as a dielectric medium, so that the motion period of propagation wave of electromagnetic radiation charges in the dielectric medium is increased, the resonant frequency of multiple wave resonance is improved, primary and secondary resonance can be generated, and antenna performances are improved; in addition, the added fillings substantially reduce the interference wave source influence to an antenna body, and stable antenna performances can be realized. The miniature high performance antenna can realize the production of miniature high performance antennas, and reduce a physical structure size by half under same performance requirements.
