Omnidirectional wideband antenna with conformal structure of installing surface

Abstract

The invention discloses an all-directional wideband antenna which has the same shape with an installation surface structure; the all-directional wideband antenna comprises a coaxial feed joint, a cylindrical back chamber (1), a glass fiber reinforced plastic cover (2), a metal upper cover (3), a metal lower cover (7), a sleeve (8), three groups of short circuit columns and three supporting frames; three groups of short circuit columns are arranged between the metal upper cover (3) and the metal lower cover (7); the three supporting frames are arranged on the internal wall of the sleeve (8) which is welded inside the cylindrical back chamber (1) and is positioned at the jointing of a conical bottom surface (101) and a transition section (103); the glass fiber reinforced plastic cover (2) is arranged on a flange platform (104) of the cylindrical back chamber (1); the frontal disc (35) of the metal upper cover (3) is attached to the glass fiber reinforced plastic cover (2); the frontal disc (35) of the metal upper cover (3) is attached to the glass fiber reinforced plastic cover (2), thus leading the all-directional wideband antenna to be internally embedded into the installation plane of a movable platform so as to form the structural conformality.

Description

technical field [0001] The present invention relates to an omnidirectional broadband antenna, more particularly, refers to an omnidirectional broadband antenna conformal to the structure of the installation surface. The antenna structure designed in the present invention is embedded and installed in the installation plane of the mobile platform. Background technique [0002] At present, the omnidirectional broadband antennas used on mobile platforms in electronic communication generally use saber antennas. Although the saber antennas have simple structure and stable electrical performance, due to the limitation of the antenna form, the saber antenna must be assembled with the platform. Protruding from the surface of the platform destroys the aerodynamic characteristics of the platform, and also has a certain impact on the electromagnetic characteristics of the platform. Contents of the invention [0003] The purpose of the present invention is to provide an omnidirectiona...
