![]() The following figures show the types of waveguides. When microwave energy travels through waveguide, it experiences lower losses than a coaxial cable. They offer very low loss (low value of alpha-attenuation). Power loss is very negligible in waveguides. They can handle very large power (in kilo watts). The empty space between the tube walls provide distributed capacitance.įollowing are few advantages of Waveguides. The tube wall provides distributed inductance. The main characteristics of a Waveguide are − Unlike a transmission line, a waveguide has no center conductor. Waveguide is a special form of transmission line, which is a hollow metal tube. The following figure shows an example of a waveguide.Ī waveguide is generally preferred in microwave communications. Microwaves propagate through microwave circuits, components and devices, which act as a part of Microwave transmission lines, broadly called as Waveguides.Ī hollow metallic tube of uniform cross-section for transmitting electromagnetic waves by successive reflections from the inner walls of the tube is called as a Waveguide. We have studied that transmission lines help the signals to travel longer distances. However, high frequency signals can't travel longer distances without getting attenuated. ![]() ![]() ![]() Generally, if the frequency of a signal or a particular band of signals is high, the bandwidth utilization is high as the signal provides more space for other signals to get accumulated.
