Problems solved by technology

However, because the antenna is protrudingly installed on the surface of the rocket body, it has a certain impact on the aerodynamic characteristics of the rocket, which increases the difficulty of the structural design of the rocket body, and due to the large amount of heat generated by friction, the thermal protection design of the antenna is more difficult

Abstract

The invention provides a rocket-borne monopole telemetering transmitting antenna and a rocket based on the same. The antenna is characterized in that radiation gain is appropriate, and the antenna iseasy and convenient to install and good in consistency, does not affect the aerodynamic characteristics of the rocket and is suitable for small carrier rockets. The antenna comprises a monopole radiator, an N-type SMA joint and a metal base. The monopole radiator comprises a feed probe and a ceramic dielectric rod. The N-type SMA joint is installed in the metal base. The ceramic dielectric rod isinstalled on the metal base. One end of the feed probe penetrates through the ceramic dielectric rod in the axial direction and is connected with the positive electrode of the N-type SMA joint. The metal base is connected with the negative electrode of the N-type SMA joint.

Description

technical field [0001] The invention belongs to the technical field of wireless transmission, and relates to an rocket-borne monopole telemetry transmitting antenna and a rocket based thereon. Background technique [0002] With the rapid development of domestic aerospace launch vehicles and telemetry technology, telemetry equipment has become an indispensable part of the pre-development and test stages. During the test process, the working parameters of each sub-system of the launch vehicle can be collected and wirelessly transmitted to the ground. Receive systems for monitoring by scientific researchers and analysis of test results. The wireless transmission of telemetry data must rely on a suitable telemetry transmitter antenna, so the design of the antenna becomes a particularly important part, which can directly affect the transmission quality of the wireless signal, the kinetic energy characteristics of the weapon system, and the analysis of test results. [0003] The ...
