Abstract

The present invention provides a horizontal polarized broadband biconical omni-directional antenna. The horizontal polarized broadband biconical omni-directional antenna comprises a biconical omni-directional antenna, a foam installation support and multiple layers of metal gate polarizers formed by a plurality of polarized grating pieces. The polarized grating pieces in the multiple layers of metal gate polarizers are metal gates with a certain deflection angle; the foam installation support is cylindrical and is sleeved at the side surface of the biconical omni-directional antenna to form acircle polarized grating piece installation base, and the polarized grating pieces are installed on the foam installation support in order in a layered winding mode; and foam strips are installed between the polarized grating piece. The horizontal polarized broadband biconical omni-directional antenna does not need arraying or a complex feed network, has broadband and horizontal polarization.

Description

technical field [0001] The invention belongs to the technical field of radar antennas, in particular to a horizontally polarized broadband biconical omnidirectional antenna. Background technique [0002] With the development of electronic technology and the requirements of military scientific research projects, omnidirectional antennas are used to achieve more and more functions, such as sidelobe concealment, frequency measurement, and inter-module networking. An omnidirectional antenna refers to an antenna that shows 360° uniform radiation on the horizontal pattern and a beam with a certain width on the vertical pattern. The horizontally polarized wideband biconical omnidirectional antenna is a kind of omnidirectional antenna, which is mainly used to conceal the sidelobe of the interference identification antenna in the search radar, so as to ensure the accuracy of the radar equipment's identification of electromagnetic signal interference. [0003] At present, the omnidir...
