Abstract

The invention discloses a 12 spiral array measurement and control antenna, relating to a measurement and control antenna device in the field of unmanned aerial vehicle measurement and control antennas. The 12 spiral array measurement and control antenna comprises twelve 14.5-circle single-winding, parasitic, conical spiral unit antennas, two one sixth non-equiamplitude power dividers, a sum and difference device, fourteen equi-phase low-loss coaxial cables, an unequal space main skeleton with a box section, a cable socket, a supporting rod and the like. The spiral array measurement and control antenna disclosed by the invention has the characteristics of high gain, low side lobe, wide frequency band, good circular polarization property and matching property, small volume, light weight, easiness in installation, suitability for vehicle-mounted and long-distance low-elevation tracking and the like, and is particularly suitable for being used as the measurement and control antenna device in the field of unmanned aerial vehicle measurement and control antennas.

Description

technical field [0001] The invention relates to a measurement and control antenna device in the field of UAV measurement and control antennas Background technique [0002] At present, there are several types of antennas that can generate fan-shaped beams. Although they have their own characteristics in performance, they also have some shortcomings. [0003] 1. Although the antenna array composed of Yagi antennas has good electrical performance, it is bulky and time-consuming and laborious to install. It is not suitable for vehicles, and the frequency band is narrow, and the circular polarization feed network is complicated; [0004] 2. Although the cutting parabolic antenna can also meet various electrical performance indicators, it cannot meet the requirements of engineering use due to the large size of the antenna. Contents of the invention [0005] The purpose of the patent of the present invention is to avoid the deficiencies in the above-mentioned background technolo...
