Abstract

The present invention relates to a radio communication device, and discloses a cylinder conformal element antenna. An oscillator is installed in a cavity which is embedded and installed on the cylinder and is conformal with the cylinder. The oscillator laterally employs a short circuit overlap mode for impedance matching. A thermal insulation radome is arranged at the surface of the antenna to allow the antenna itself to prevent a carrier from high-temperature calcinations caused by high-speed flight. The cylinder conformal array can be conformal with the carrier and does not destroy the machinery structure of the carrier. The space is saved. The cylinder conformal element antenna has a special electrical index, appropriate structure mode and satisfied mechanical strength and can normally work in the adverse conditions. The cylinder conformal element antenna solves the problem that the current oscillator antenna cannot be conformal with the cylinder and obtains the beneficial effect that the antenna has good work in the high-speed flight state of the carrier.

Description

technical field [0001] The invention relates to radio communication equipment, in particular to a cylindrical conformal dipole antenna. Background technique [0002] With the development of aircraft, rockets, missiles, satellites and other aircraft in aviation and spaceflight, modern space radio electronic equipment is widely used in aircraft. There are as many as dozens of antennas for aircraft. Some are larger than the body of the aircraft, and some are most of the surface of the aircraft. It can be seen that there is an inseparable relationship between the antenna and the carrier, and it is completely suitable for the antenna and the carrier to be conformal. The conformal antenna and the conformal antenna array will play an increasingly important role today and in the future. [0003] Conformal antenna array requires high gain, low sidelobe, shaped beam and scanning application, and its structure and form are various. It can be formed into a linear array, a planar ar...
