Abstract

The invention relates to the technical field of antennas, in particular to an omni-directional vertical polarization broadband VHF waveband antenna used for ground communication station installation.The antenna comprises antenna radiation oscillators, antenna medium pillars and an antenna reflection disc; the antenna radiation oscillators adopt symmetrical structural layout, the expansion of working bandwidth in a VHF frequency band is realized through gradually varied distribution of the proportionality coefficients of vertical inverted trapezoidal surfaces to horizontal inverted trapezoidalsurfaces inside the antenna radiation oscillators, and the function, in the radiation direction, of the antenna is controlled; the antenna reflection disc adopts a structure fusion design that the equivalent area is compressed longitudinally upwards, and the installation dimensions, in all directions, of the antenna are decreased to a greater extent compared with those of other antennas, so thatthe requirements, such as convenience, portability and compact installation, of the antenna are met. The antenna provided by the invention meets the vertical polarization and omni-directional radiation requirements in the VHF working frequency band on electrical performance, has the characteristics of high radiation efficiency and excellent antenna parameters, and is wide in application prospects.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to an omnidirectional vertically polarized broadband VHF band antenna for installation in ground communication stations. Background technique [0002] In communication technology, VHF is the abbreviation of Very High Frequency, that is, very high frequency, which refers to radio waves with a frequency band from 30MHz to 300MHz. The VHF communication frequency band is a commonly used working frequency band in the field of mobile communication and measurement and control communication. Its working wavelength is relatively long, the diffraction phenomenon is obvious, and the ability to penetrate the medium is strong, so it has a good ability to resist atmospheric environment interference. . [0003] At present, in mobile communication, the ground communication station generally requires the antenna itself to have the ability of vertical polarization and omnidirectional comm...
