Problems solved by technology

Its shortcoming is that the structure is complex and requires a large rotation space and servo power
Its disadvantages are that the amount of equipment is large, and the RF insertion loss is large, resulting in low equivalent surface efficiency.
Its disadvantage is that the design of the parabolic reflector and the primary feed is complicated, and the gain of the antenna decreases greatly when the scanning angle is large.

Embodiment Construction

[0024] Referring to Fig. 1 to Fig. 3, the present invention adopts array antenna feeding, and realizes beam scanning technology by rotating the antenna reflecting surface, including steps:

[0025] ①The array antenna 1 is designed according to the working frequency, and the array antenna 1 is designed with M×N array units 11 according to the requirements of the antenna gain. M or N is a natural number greater than 1, and the array antenna 1 is installed on the On the antenna platform, the radiation beam is directed to the reflecting mirror 2 . The array structure of the array antenna 1 of the present invention is a rectangular array, or a circular array, or a tapered distribution array, or a rectangular array with unequal spacing, or a tapered distribution array with unequal spacing. The array unit 11 of the present invention is configured as a microstrip antenna, or an antenna in the form of a waveguide, or a slot antenna, or a horn antenna, or an antenna in the form of a vib...

Abstract

This invention discloses a manufacturing method for a mirror scan array antenna composed of an array antenna, a mirror rotation unit and a reflection mirror, and the method applies a feeding mode of array antenna to realize wave beam scanning by rotating the reflection mirror. Advantages: compact structure, small volume, light weight, simple servo structure and low process cost.

Description

technical field [0001] The invention relates to a manufacturing technology of a mirror scanning array antenna in the field of mobile satellite communication and mobile measurement and control, and is especially suitable for the manufacture of various satellite communication or single receiving antennas working in vehicle-mounted or ship-borne mobile satellite communication, measurement and control applications . Background technique [0002] At present, three methods are mainly used to enable the satellite communication antenna to communicate with the satellite in the case of vehicle and ship: [0003] One is to use a traditional parabolic antenna or an array antenna, and the azimuth and pitch are mechanically controlled to drive the entire antenna to rotate. Its shortcoming is that the structure is complex and requires a large rotation space and servo power. [0004] The second is to use a low-profile array antenna. The azimuth plane adopts a mechanical control method to ...
