Intonation section probe 9 is to ensure that back cavity does not generate higher mode in 2~18GHz frequency ranges.Feed probes use two sub-miniature A connectors
Just coaxial cable electric connection 8, cable size are less than 2mm to the half of connection, and two feed probes right angle settings correspond to feed respectively
Two polarization.
The metal of the well conductings such as aluminium, copper may be employed in the processing of modified quadruple ridged horn antenna, preferred real as one
Example is applied, using duralumin as rapidoprint.
For the main lobe pattern division that four ridge waveguide loudspeaker is overcome to be present with after more than 3 octaves, phase center becomes
Change the problems such as big, introduce polytetrafluoroethylene (PTFE) and loaded.Coated by dielectric device uses circular cone 10a, round platform 10b and hemisphere 10c tri-
Segmentation structure.Cone tip is 72mm apart from bell mouth surface distance, and circular cone 10a bottom surfaces are identical with the diameter of round platform 10b bottom surfaces,
Between taking 58~62mm, hemisphere 10c diameters are identical with round platform 10b upper surfaces diameter, are 19.2mm.Coated by dielectric device 10 uses

Using the ultra wide band electromagnetic horn of coated by dielectric in order to ensure that high band directional diagram amplitude taper is small, in entire frequency range
Phase center variation is small, reduces Antenna aperture to the greatest extent, shortens axial length.Therefore the ultra wide band of the coated by dielectric of design
Electromagnetic horn has higher back lobe, in actual compact feed system, often there is complicated supporting structure behind feed,
The supporting structure is generally metal material, which easily generates secondary radiation, it is therefore necessary to reduce since stent causes
Secondary radiation.Invention introduces the support columns 2 of lengthening, and Feed Horn aerial radiation mouth face is pushed away supporting structure, support
Column 2 is between coated by dielectric quadruple ridged horn antenna 1 and ring flange 3, and length is between 255~355mm, as shown in Figure 3.By adjusting
The height of support column 2 makes feed phase center be overlapped in reflecting surface focus.Feed branch is blocked using taper absorbing material 4 simultaneously
The major part of frame system.4 vertex of a cone of absorbing material carries out 4 reflectivity of absorbing material no more than feed aperture, the present invention
Emulation using binary arrays model, calculates the absorbing material minimal reflection filtering met corresponding to feed pattern requirements.To not
With height absorbing material, corresponding difference absorptivity, establishes simple binary battle array simulation model, compares binary arrays directional diagram, determines to inhale
4 material of ripple material highly cannot be below 45mm, consider entire feed structure select 4 height of absorbing material between 45~60mm most
It is preferable.4 area of absorbing material is more big more is conducive to inhibit the secondary radiation that back lobe motivates, but in view of the structure of feed source bracket
Absorbing material is excessive inconvenient to use, and the absorbing material that should be chosen is the smaller the better, by simulation calculation, selects length and width 400
~500mm is the most reasonable.Ring flange 3 is used to connect feed and feed source bracket.The ultra-wideband compact feed of entire coated by dielectric
