Elliptical Waveguide

Product Description

An elliptical waveguide is a type of waveguide with an elliptical cross-section. It is easy to install and light in weight; the transmission waveform is also relatively stable. Therefore, in terms of long-distance microwave transmission, satellite communications and other electronic devices have a wide range of applications.

The cross section of an elliptical waveguide is elliptical. It can be made of copper or aluminum, and the waveguide wall can be corrugated or without surrounding structure; generally have a certain flexibility and flexibility.

Advantage:

(1) Save copper and reduce costs.

(2) Light weight, simple and time-saving laying, easy to cross obstacles.

(3) Small attenuation, when the long axes are equal, the attenuation is smaller than that of the elliptical waveguide.

(4) The characteristic impedance is similar to that of the rectangular waveguide, and it is easy to match the two in a wide frequency band.

(5) There are many parameters representing the geometry of the cocoon-shaped interface, and the design freedom is large.

(6) Easy to manufacture in large lengths, up to several hundred meters. It can also be wound on a cable reel, suitable for transporting large lengths.

(7) Because the overall effect of the circuit design is close to or better than that of the rectangular rigid waveguide system, it has the advantages of stable polarization, good air tightness and reliable performance.

Uses: Elliptical waveguide as antenna feeder is widely used in electronic equipment such as mobile communication, microwave relay communication, satellite communication ground station, UHF TV and ship radar, and is considered to be the most promising new type of feeder in the centimeter band.

Specification

Application

Rectangular and circular metal waveguides are widely used, but when they are used as waveguides to transmit energy over long distances, many difficulties are encountered in construction and installation.

Among them, for circular waveguides, slight changes in structure and size will cause changes in the transmission waveform or rotation of the polarization plane. The use of elliptical waveguide can overcome these difficulties very well.

Compared with rectangular and circular waveguides, elliptical waveguides can be made longer, can save many connecting elements, can be bent, and are easy to lay; under the same requirements, the weight is lighter; the transmission waveform is also more stable.

Therefore, in terms of long-distance microwave transmission, satellite communications and other electronic equipment have been widely used.
