Abstract

The invention provides a miniaturized broadband oblique polarization type omni-directional antenna. An oblique polarization type radiation unit comprises single-cone radiation bodies disposed along a central axis, lower parasitic short piles, cage-shaped parasitic bodies and polarization deflectors. The single-cone radiation bodies are connected to realize the coaxial feed. The lower parasitic short piles are arranged at the periphery of the lower parts of the single-cone radiation bodies. The cage-shaped parasitic bodies are arranged above the lower parasitic short piles and at the periphery of the middle parts of the single-cone radiation bodies. The polarization deflectors are arranged at the periphery of the single-cone radiation bodies, the lower parasitic short piles and the cage-shaped parasitic bodies. According to the technical scheme of the invention, the miniaturization and the ultra wideband of the antenna are realized in the above loading manner. The polarization deflectors are used for converting vertically polarized waves into obliquely polarized waves. Therefore, the antenna has the capability of simultaneously receiving vertical polarization signals and horizontal polarization signals. Meanwhile, the technical requirements of vehicle-mounted radio direction finding / monitoring antenna can be met.

Description

[0001] 【Technical field】 [0002] The invention relates to a radio direction-finding and monitoring antenna device and technology, in particular to a miniaturized broadband obliquely polarized omnidirectional antenna and its technology. [0003] 【Background technique】 [0004] As we all know, radio frequency spectrum is an extremely precious and scarce resource because of its exclusiveness and specialization. Due to the problem of co-channel interference, the spectrum required for radio services usually requires special planning and authorized allocation. Therefore, all countries have established national-level radio management organizations, such as the State Radio Management Committee of China and the FCC of the US Federal Communications Commission. Radio direction finding and monitoring is an important daily work of the National Radio Regulatory Commission. Monitor the authorized frequency band at all times to determine whether there is any illegal use by organizations or ...
