Waveguide Bends

Waveguide Bends Waveguide is normally rigid, except for flexible waveguide, and therefore it is often necessary to direct the waveguide in a particular direction. Using waveguide bends and twists it is possible to arrange the waveguide into the positions required.  When using waveguide bends and waveguide twists, it is necessary to ensure the bending and twisting is accomplished in the correct manner otherwise the electric and mag Read More

Waveguide Directional Coupler

Waveguide Directional Coupler A waveguide directional coupler is only a directional coupler realised in a format using waveguide technology. A waveguide coupler provides a means of sampling the energy travelling within a waveguide, and as most couplers are directional in nature, sampling energy travelling in one direction, they are called waveguide directional couplers. Waveguide couplers are available that sample the energy travelling Read More

Waveguide Junction

Waveguide Junction Waveguide junctions are used when power in a waveguide needs to be split or some extracted. There are a number of different types of waveguide junction that can be use, each type having different properties - the different types of waveguide junction affect the energy contained within the waveguide in different ways. When selecting a waveguide junction balances between performance and cost need to be made and therefo Read More

Waveguide flanges, couplers and transitions

Waveguide flanges, couplers and transitions A signal can be entered into the waveguide in a number of ways. The most straightforward is to use what is known as a launcher. This is basically a small probe which penetrates a small distance into the centre of the waveguide itself as shown. Often this probe may be the centre conductor of the coaxial cable connected to the waveguide. The probe is orientated so that it is parallel to the lines o Read More

Flexible Waveguide

Flexible Waveguide Flexible waveguide is often used to connect two elements using rigid waveguide systems together, especially when they cannot be accurately located or positioned.. For example, flexible waveguide is often used to connect antenna systems, especially when they may not be fixed, to the base transmitter receiver system. Flexible waveguide may not have the same level of performance that is provided by rigid waveguide, but Read More

Waveguide Cut off Frequency

Waveguide Cut off Frequency    The cutoff frequency is the frequency below which the waveguide will not operate. Accordingly it is essential that any signals required to pass through the waveguide do not extend close to or below the cutoff frequency. The waveguide cutoff frequency is therefore one of the major specifications associated with any waveguide product.   Waveguide cut off frequency basics Waveg Read More

Waveguide Impedance and Impedance Matching

Waveguide Impedance and Impedance Matching Waveguide impedance can be important in a number of applications. In the same way that the characteristic impedance is important for other forms of feeder, the same can be true in a number of instances with waveguides. Techniques including the use of a waveguide iris, or a waveguide post can be used to provide the required level of waveguide impedance matching. The waveguide impedance needs to Read More

Waveguide theory

Waveguide theory In order to be able to use waveguides to their best effect, it is necessary to have a basic understanding of waveguide theory, including propagation and the propagation constant. While waveguide theory can become particularly involved, it is not the aim here to delve too deeply into the waveguide theory mathematics. Waveguide theory is based around electromagnetic wave theory because the waves propagating along wavegui Read More

Waveguide Microwave RF Feeder

Waveguide Microwave RF Feeder  RF waveguides are a form of RF feeder or transmission line used for microwave applications.  The basics of waveguide technology are easy to comprehend, although the mathematics involved can become complicated when wave theory and the like are used. Waveguides, as the name indicates are a guide for electromagnetic waves and this way they enable them to feed power from one location to another. Read More
