Abstract

The invention discloses a helical antenna flexible support apparatus used for solving the support of a helical antenna. The helical antenna flexible support apparatus comprises a dielectric slab and multiple flexible support filaments. The bottom of the helical antenna is installed on the dielectric slab through multiple dielectric bases distributed uniformly and circumferentially. The multiple flexible support filaments are distributed around the helical antenna radially and uniformly, are arranged along the axial direction of the helical antenna, and are connected with each layer of the helical antenna through a thread pitch fine tuning apparatus. The helical antenna flexible support apparatus controls the thread pitch and the rigidity of the helical antenna by using the restoring force of the helical antenna and the unidirectional support characteristic of the flexible filaments. Compared with a conventional helical antenna hard support apparatus, the helical antenna flexible support apparatus greatly decreases the weight of a helical antenna apparatus and may achieve screwing compaction release so as to greatly reduce the installation enveloping space of the helical antenna.

Description

technical field [0001] The invention relates to the technical field of antenna supporting devices, in particular to a flexible supporting device for a helical antenna. Background technique [0002] The helical antenna is a kind of antenna widely used in the aerospace field, which has excellent circular polarization radiation performance. Traditional helical antennas require a rigid dielectric structure to support the helix, and the rigid dielectric support structure provides support, fixation and protection for the helix. However, for large-scale helical antennas used in low frequencies, the highly rigid antenna support columns seriously occupy the space of the aircraft platform and greatly increase the weight and volume of the antenna. Contents of the invention [0003] In order to solve the above problems, the present invention provides a helical antenna flexible support device, the helical antenna flexible support device includes a helical antenna, a dielectric plate, ...
