Abstract
The corrugation circular recess waveguide antenna is a kind of waveguide antenna for microwave, millimetric wave and submillimeter wave.Said antenna consists of antenna upper conductor and antenna lower condutor, through-hole fixing screws and insulating blocks. Between upper and lower conductors, there are insulating blocks to separate said two conductors at both sides respectively, and the symcenter of end face of the antenna conductor is equipped with a circular through-hole along the antenna conductor length direction, i. e. propagation direction of the wave, and on the circular through-hole, there is a conical through-hole, and on the peripheral wall of the circular through-hole and conical through-hole, there are ring grooves with the same axis as these through-holes.
Description
The present invention is a kind of radiating guide that is used for microwave, millimeter wave and submillimeter wave, is a kind of corrugated circular slot waveguide antenna.
In communications applications or in the non-communications applications, often need to produce the antenna of sharp-pointed wave beam, though and present fold circular waveguide antenna has the field distribution of linear polarization preferably, its size is less, the power of transmission is also less.Microwave, millimeter wave and submillimeter wave wave band have polytype transmission waveguide, for example rectangular waveguide, circular waveguide, circular recess wave guide etc., they are all one by one to should there being the antenna that is based upon on the waveguide basis own, and corrugated circular slot wave guide does not also have corresponding antenna so far.
Purpose of the present invention just provides the field distribution of a kind of existing linear polarization preferably, can transmit powerful corrugated circular slot waveguide antenna again.
Corrugated circular slot waveguide antenna of the present invention is mainly by the antenna upper conductor of this antenna, the antenna lower conductor, the punching fixed screw, collets are formed, being respectively equipped with collets on antenna upper conductor and both sides between the antenna lower conductor separates antenna upper conductor and antenna lower conductor, being provided with one in the symmetrical centre position of antenna conductor end face is the manhole of the transmission direction of ripple along the antenna conductor length direction, the diameter d of manhole＞0.5 wavelength, on manhole, also be provided with conical through-hole, on the circle wall of manhole and conical through-hole, also be provided with the cannelure identical with the conical through-hole axis with manhole.The diameter d of cannelure on manhole and the conical through-hole
oAnd the pass between the diameter d of manhole or conical through-hole is d/d
o=0.15～0.95.The tapering α of conical through-hole be 5 spend to 90 the degree.The width b of cannelure is less than the cycle c of cannelure, greater than half of cannelure cycle.On the inwall of the collets between antenna upper conductor and the antenna lower conductor, scribble and absorb electromagnetic material.The height of collets is greater than 0.06 wavelength, less than 1.8 wavelength.
The invention has the advantages that:
1. can transmit higher power than conventional radiating guide.
2. there is better linear polarization to distribute than conventional radiating guide.
3. it can be processed in two, greatly facilitates processing technology, has reduced production cost.
Fig. 1 is a structural representation of the present invention.Antenna upper conductor 2 is wherein arranged, antenna lower conductor 3, collets 1, punching fixed screw 4, manhole 5, cannelure 7.
Fig. 2 is that the A-A of Fig. 1 is to the sectional structure schematic diagram.Manhole 5 is wherein arranged, cannelure 7, conical through-hole 6.
Fig. 3 be the B-B of Fig. 1 to the sectional structure schematic diagram, antenna upper conductor 2 is wherein arranged, antenna lower conductor 3, collets 1, punching fixed screw 4, manhole 5, conical through-hole 6, cannelure 7.
Embodiment of the present invention are as follows: at first produce antenna upper conductor 2 and antenna lower conductor 3, choose two identical metal plates according to the wavelength X decision antenna upper conductor of the microwave of required transmission and the size of antenna lower conductor, the width of its conductor adds 4 millimeters (promptly＞4mm+3 λ) greater than 3 times wavelength, height adds 1 millimeter loudspeaker opening D that adds antenna (λ+1mm+D) promptly＞0.5 greater than 0.5 times wavelength, on four angles of this antenna upper conductor and antenna lower conductor, respectively bore a through hole, be fixed with adapter lug then, the manhole 5 that elder generation processes a diameter on lathe be d, d＞0.5 wavelength, in manhole, process conical through-hole 6 at length direction then by cone angle along the hole, mill the part that this antenna upper conductor and antenna lower conductor have machining hole one side afterwards more respectively on lathe, its height that mills is respectively half of collets height.Reprocess out cannelure 7, the diameter d of cannelure on manhole and the conical through-hole
oAnd the pass between the diameter d of manhole or conical through-hole is d/d
o=0.15～0.95, the dimension α of conical through-hole=5 °～9 °, the width b of circular trough is less than the cycle c of cannelure, greater than half of cannelure cycle, the inwall of the collets between the upper and lower conductor of antenna scribbles and absorbs the electromagnetic wave material, and the height of collets is greater than 0.06 wavelength, less than 1.8 wavelength.Collets adopt bakelite or polymethyl methacrylate or quartz glass etc.Both sides between antenna upper conductor and the antenna lower conductor are encased inside collets 1 respectively, and with antenna upper conductor 2, antenna lower conductor (3), collets 1 are fixed and have just been formed corrugated circular slot waveguide antenna of the present invention with the punching fixed screw.
