Abstract
The invention discloses a high-gain airborne omnidirectional short-wave loop antenna, which comprises: an isosceles trapezoid metal sheet; a rhombic metal sheet, wherein the rhombic metal sheet is located above the isosceles trapezoid metal sheet and is parallel to the isosceles trapezoid metal sheet, and the projection of the long diagonal line of the rhombic metal sheet and the projection of the midpoint connecting line of the upper bottom edge and the lower bottom edge of the isosceles trapezoid metal sheet in the vertical direction coincide; two straight-strip-shaped open circuit branches symmetrically distributed on the two horizontal sides of the rhombic metal sheet, wherein one end of the open-circuit branch is connected with the first end of the rhombic metal sheet through the first short-circuit branch, the other end of the open-circuit branch extends outwards, so that an included angle is formed between the open-circuit branch and the long diagonal line of the rhombic metal sheet, and the projection of any open-circuit branch vertically falling on the isosceles trapezoid metal sheet does not exceed the isosceles trapezoid metal sheet; and a second short-circuit branch knot connected with the second end of the rhombic metal sheet and the lower bottom edge of the isosceles trapezoid metal sheet. The short-wave loop antenna provided by the invention has the characteristics of high gain, omnidirectivity and miniaturization.
Description
technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a high-gain airborne omnidirectional short-wave loop antenna. Background technique [0002] Short-wave communication is a radio communication operating in the frequency range of 3MHz to 30MHz, which uses the reflection of the earth's ionosphere to achieve long-distance wireless signal transmission. Shortwave communication has excellent performance in some special communication environments, and has the characteristics of long transmission distance, strong resistance to destruction, flexibility and reliability, etc., and is widely used in international communication, emergency rescue and relief, military affairs, meteorology and other fields. [0003] Airborne short-wave antenna is an indispensable part of the aircraft communication system as the front end of the wireless signal transmission and reception in the aircraft communication system. It is mainly used for lon...
