SOLID DIELECTRIC WAVEGUIDE WITH METAL PLATING Filed Jan. 5, 1946 INVENTOR LESTER C. VAN ATTA GEORGE G. HARVEY FIG. 4
ROBERT A. F'AIRBAIRN BY A ORNEY SOLID DIELECTRIC WAVEGUIDE WITH METAL PLATING Lester C. Van Atta, Winchester, George G. Harvey, Boston, and Robert A. Fairhairn, Needham, Mass, as-
signors, by mesne assignments, to the United States of America as represented bythe Secretary of theNavy Application January 5, 1946, Serial No. 639,280 i 3 Claims. (Cl. 343-771) This invention relates to waveguides, and more particularly to waveguides employing a solid dielectric substance as the propagating medium.
Heretofore, waveguides of the hollow pipe variety have consisted of rugged metallic walls containing air as the propagating medium, but these are bulky, diificult to construct, and are not easily adapted to the problem of feeding properly phased energy to the radiating elements of an antenna array.
An object of the present invention is to provide a small and simply constructed waveguide for carrying electromagnetic waves without serious energy loss.
Another object is to provide a waveguide utilizing a solid dielectric substance as the propagating medium.
Another object is to provide a waveguide which is readily adaptable for use as a slot type radiator.
A still further object is to provide a waveguide whose physical dimensions are not appreciably attected by variations in temperature.
To achieve the above objects, a form of waveguide is constructed which comprises a solid dielectric rod, commonly of rectangular or circular cross-section, which is plated on its outer surf-ace with a good conducting material such as copper or silver.
The invention is fully described in the following specification and the drawings of which:
Fig. 1 is a perspective view of a rectangular waveguide constructed in accordance with the invention;
Fig. 2 is a perspective view of a circular Wave guide constructed in accordance with the invention;
Fig. 2A is a perspective view of the waveguide of Fig. 2 adapted to become a coaxial line;
Fig. 3 is a view of an antenna utilizing the waveguide of this invention as a feed;
Fig. 4 is a view of the waveguide of this invention used as a radiator.
Referring specifically to Figs. 1 and 2, the waveguides shown are formed from a solid strip or rod of a lowloss dielectric material such as polystyrene. The outer surface of strip or rod 10 is coated or plated with a good conducting material such as copper or silver to form a covering 11. This conducting material may be applied by a known process such as electroplating. Electromagnetic energy is propagated through the dielectric rod or strip 10 and is confined therein by the conducting material coated or plated thereon.
By the use of a dielectric propagating medium, the Wave length of energy in rectangular waveguide is lessened in accordance with the well known equation and dielectric constant in air and A and e are wave length and dielectric constant in the guide. As a result,
Gil
Patented Aug. 28, 1956 the required physical dimensions of the guide are lessened, thus providing desired compactness.
it will be obvious to those skilled in the art that the circular Wave guide of Fig. 2 may be adapted, as in Fig. 2A, to use as a coaxial line by disposing a conducting rod 12 in the dielectric material 10 along the axis of the outer conducting sheath 11. The well known coaxial line wave length equation whose symbols are consistent with those defined above, indicates that the wave length of energy in the coaxial line may be diminished as in the above wave guide example by the introduction of a solid dielectric propagating material. Such changes of wave length in coaxial line do not, however, affect the diametrical dimensions of the line which are determined by voltage gradient considerations alone. I
The electrical length of a solid dielectric wave guide or coaxial line depends on dielectric constant, and in a number of applications, this type of phase control is advantageous. Fig. 3 illustrates an example of such a situation and shows a linear antenna array having a reflector 15 and dielectric wave guides 16 feeding an array of dipoles 17. Such array is designed for broadside radiation (i. e. outward in a direction perpendicular to the plane of the reflector) and this requires that all the dipoles be excited in phase but that they be geometrically arranged so that their side radiation is cancelled. By the use of dielectric wave guide 16 or dielectric coaxial line to feed the radiating elements 17, these conditions are easily achieved and without the necessity of driving alternate dipoles in phase opposition.
Dielectric wave guide is also used to advantage in endfire antenna arrays wherein it is desired that the wave length of energy in the wave guide feeding the dipoles be the same as that in free space.
Wave guides having radiating apertures such as slots are easily constructed from the guides of Figs. 1 and 2 by either selective plating or by scraping away plating where it is not needed. Such a radiator, having radiating slots 18, is shown in Fig. 4.
For situations where it is desired to keep the temperature expansions and contractions of a Wave guide at a minimum, a low expansion dielectric material is used in the wave guide of this invention. The metallic plating on the dielectric is very thin and its dimensional variations with temperature are thus negligible.
The invention described in the foregoing specification need not be limited to the details shown, which are considered to be illustrative of certain forms the invention may take. What we desire to be secured by Letters Patent and claimed is:
l. The method of fabricating a wave guide component for the transmission of electromagnetic energy which comprises the steps of forming from a low loss solid di electric material a member having a shape and cross section corresponding to the wave guide component desired, plating the surface of said dielectric member with a metallic coating sufiiciently thick to confine electromagnetic energy within said medium without radiation loss and removing predetermined areas through which electromagnetic 2. The method of fabricating an antenna for the radiation of electromagnetic energy which includes the steps of forming from a low-loss solid dielectric material a member having the shape and cross section corresponding to that of the antenna desired, electroplating to the outer surface of said member a layer of conductive material of said metallic coating energy is to pass.
having a thickness suflicient to confine electromagnetic energy within said member Without radiation loss yet thin enough to be substantially unaifected dimensionally by normal temperature variations and removing portions of said conducting layer at predetermined locations to permit radiation therethrough, the shape of said portions removed determining the beam characteristics of the antenna.
3. A wave guide member for the propagation of electromagnetic energy comprising a solid, low-loss dielectric member having a shape and cross-section corrcsponcling to that of the waveguide component desired, said member having selected areas of its outer surface coated with a metallic deposit of a thickness sufficient to confine electromagnetic energy wi-thin said dielectric member Without radiation loss therethrough and of a thinness sufficient to be substantially unaffected dimensionally by normal temperature variations.
