Abstract
The present invention relates to a corrugated circular slot waveguide antenna used for microwaves, millimeter waves and sub millimeter waves. The antenna is composed of an upper conductor of the antenna, a lower conductor of the antenna, piercing fixing screws and insulation blocks, wherein the insulation blocks which make the upper conductor of the antenna and the lower conductor of the antenna separated are respectively arranged on both sides between the upper conductor of the antenna and the lower conductor of the antenna; the symmetric center position of the conductor end surfaces of the antenna is provided with a circular through hole along the length direction of the antenna conductors, namely the transmission direction of the waves; the circular through hole is also provided with a conical through hole, and the circumferential walls of the circular through hole and the conical through hole are also provided with annular slots which have the same axial lines with the circular through hole and the conical through hole.
Description
One, technical field:
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.
Two, background technology:
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 the corrugated circular slot ripple does not also have corresponding antenna so far.
Three, summary of the invention:
(1) technical problem
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.
(2) technical scheme
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 provided with collets on antenna upper conductor and both sides between the antenna lower conductor separates antenna upper conductor and antenna lower conductor, the punching fixed screw passes the antenna upper conductor, collets, antenna, with the antenna upper conductor, collets, the antenna lower conductor is linked to be an integral body, 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 axis cannelure identical with the conical through-hole axis with manhole.The diameter d of five shape grooves on manhole or the conical through-hole
0And the pass between the diameter d of manhole or conical through-hole is d/d
0=0.15～0.95.The tapering 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.
(3) technique effect
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.
