The invention discloses an ultra-wideband dipole antenna, which comprises a dielectric plate, a coupling branch structure and two dipole arms with the same shape; and the dipole arms are hollow curvedsurface shells and are symmetrically arranged by taking the dielectric plate as a central plane so as to be used as a wideband feed source of the dipole antenna, wherein the curved surface of each dipole arm comprises an ellipsoidal curved surface and an arc-shaped curved surface. The coupling branch knot structure comprises four coupling branch knots, the coupling branch knots are symmetricallyarranged at the periphery of the two dipole arms, and the antenna is used as a multi-band source of the dipole antenna. Each coupling branch knot is of a strip-shaped metal bent broken line structure,due to the fact that a broadband feeding strategy that a curve cone is used for feeding is adopted, a pair of dipole antennas can meet the wide frequency range, the technical problems that a common dipole antenna is large in size and needs to be designed in a multi-segment mode are solved, and the requirements of various occasions are met.
Description
technical field [0001] The application relates to the technical field of multi-frequency broadband dipole antennas, in particular to an ultra-wideband dipole antenna. Background technique [0002] Dipole antennas are widely used in the field of mobile communication devices and microwave energy collection and transmission due to their simple structure, low manufacturing cost and good performance. A traditional dipole antenna consists of two conductors fed at a central location with a total length of about half a wavelength and is the basic unit of most antennas. The dipole antenna has a certain improvement in gain pattern performance compared with the monopole antenna, and can obtain satisfactory pattern characteristics, and the dipole antenna has good radiation characteristics, wavelength shortening effect and resonance characteristics. By controlling the relationship between the current amplitude, phase and spatial position on the dipole, the dipole antenna can be widely u...
