Problems solved by technology

From the analysis of domestic and foreign literature, it is still difficult for ultra-wideband antennas to meet the requirements of ultra-wideband (covering UHF, X, and Ku bands at the same time), miniaturization, wide beam, high gain, and composite polarization. This is a serious constraint. Research and development of direction finding system in ultra-wideband direction

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

Abstract

The invention discloses an ultra-wideband composite polarized antenna, which comprises a feed balun, a reflection mounting panel, a reflection back cavity, a composite polarized radiator and a matching network, the feed balun is fixed on the bottom surface of the reflection mounting panel through a standard SMA flange; a probe of the feed balun is fixedly connected with the bottom of a reflection back cavity positioned on the front surface of the reflection mounting panel; the composite polarization radiator is fixed at the top of the reflection back cavity; the matching network is electrically connected with the composite polarization radiator and then is fixed with the reflection installation panel. The requirement that the direction finding system covers UHF, S, C and X wave bands and the Ku wave band at the same time is met, integrated development and design of the direction finding system are facilitated, and the using efficiency of the direction finding system on all platforms is improved.

Description

technical field [0001] The invention belongs to a direction finding system, and in particular relates to an ultra-wideband composite polarized antenna. Background technique [0002] The ultra-wideband direction finding system can accurately obtain the characteristic parameters of the target, and determine the attribute and category of the target. Usually, the working frequency band covers a wide range, that is, 0.5GHz-40GHz. With the requirement of technology development, the requirement for working bandwidth is higher, and the direction finding system often adopts the system of digital interferometer, and the number of channels depends on the division of the working frequency band of the direction finding array antenna. Usually the working frequency band of the antenna is 0.5GHz-0.8GHz, 0.8GHz-2.0GHz, 2.0GHz-6.0GHz, 6.0GHz-18.0GHz, 18.0GHz-40.0GHz. Therefore, the amount of antenna array equipment in the direction finding system is extremely large, which is not conducive to...
