Problems solved by technology

[0003] In the field of helical antennas, the existing helical wire fixing method is generally fixed by soldering, and the lack of double protection is unreliable and causes the antenna itself to be too heavy.
In addition, traditional helical antennas mostly use glass fiber reinforced plastics to paste the skeleton and then machine them into shape. The processing takes a long time, it is difficult to realize complex configuration processing, and the dielectric constant of the finished product is poor, which is not suitable for modern rapid and mass production mode.
The outer conductor of the traditional helical antenna is mostly made of brass, which is heavy and expensive to launch

Abstract

The invention provides a helical antenna, which comprises a skeleton, a helical groove, a conductor part and a helical line, wherein the helical groove is formed in the outer wall of the skeleton; the conductor part is arranged in the skeleton; a body part of the helical line is connected with the helical groove in a fit manner; one end of the helical line is fixedly connected to the conductor part and is connected to the bottom part of the skeleton; and the other end of the helical line is fixed at the position, close to the head, of the skeleton. The helical line fixing method is relatively reliable and light in weight.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a helical antenna. Background technique [0002] Microwave communication is a communication system with microwave as the carrier. In the microwave system, the antenna is used to complete the conversion from guided wave to radiated wave. In order to improve the performance of large-scale ground microwave reflector antennas for satellite tracking and communication applications, the antennas in existing spaceborne microwave communication systems mostly use helical antennas. [0003] In the field of helical antennas, the existing helical wire fixing method is generally fixed by soldering. The lack of double protection is unreliable and causes the antenna itself to be too heavy. In addition, traditional helical antennas are mostly made of glass fiber reinforced plastic paste and then machined into shape. The processing takes a long time, it is difficult to realize complex confi...
