What are the Differences between horn antenna and waveguide?
waveguide is a metal pipe that contains and guides microwaves from place to place in a microwave system (e.g. oscillators, amplifiers, mixers, modulators, filters, antennas)horn antenna has a waveguide connected at its focus, in transmit mode the waveguide feeds the horn which then emits a microwave beam, in receive mode the horn collects a microwave beam and concentrates it int the waveguide
Why must the air inside a waveguide be dehumidified?
Moisture in the air in a waveguide can scatter the microwave energy the waveguide is designed to transport. This translates into signal loss or attenuation. The VSWR drops, and that is not a good thing.
What is the dominant mode in rectangular waveguide?
Rectangular Waveguide - TE10; (TM11 in case of TM waves) Circular Waveguide - TE11;
What is group velocity in waveguide?
Group velocity in a waveguide is speed at which EM energy travels in the guide.It will always be less then speed light.
Which antenna is best excited by a wave guide?
Horn Antenna is best exited by waveguide
What is detector mount in waveguide and its function?
used to detect the microwave signal

What is the function of a microwave switch in electronic devices?
A microwave switch in electronic devices is used to control the flow of microwave signals, allowing them to be directed to different components or pathways within the device.
Why is microwave circuit design often considered 'more of a plumbing job than a wiring job'?
Because microwave circuits in waveguide use hollow waveguide sections with flanges to bolt them together.
Why must the air inside a waveguide be dehumidified?
Moisture in the air in a waveguide can scatter the microwave energy the waveguide is designed to transport. This translates into signal loss or attenuation. The VSWR drops, and that is not a good thing.

What are the practical applications of horn antenna?
microwave. it couples the waveguide to open space.
What are the key components of a microwave cavity and how do they contribute to the efficiency of a microwave system?
The key components of a microwave cavity are the walls, the magnetron, and the waveguide. The walls of the cavity reflect and contain the microwaves, the magnetron generates the microwaves, and the waveguide directs the microwaves into the cavity. These components work together to efficiently generate and distribute microwaves for cooking or heating food.
What is a bus waveguide?
A bus waveguide is a type of waveguide structure used to guide electromagnetic waves, typically in the microwave or optical frequency ranges, along a defined path. It consists of a central conducting or dielectric channel that allows multiple signals to travel simultaneously, often used in integrated circuits or photonic devices. By enabling efficient transmission and coupling of signals, bus waveguides play a crucial role in communication systems and signal processing applications.
What is the use of attenuator in microwave test bench?
variable attenuator in microwave test bench is used to attenuate the amplitude of wave traveling through d rectangular waveguide
Can you give Example for microwave devices?
microwave oven is one the example of microwave.
Why rectangular wave guide is preferred over a square waveguide for usual microwave transmissions?
A square waveguide does not allow single mode operation as for example fc(TEmn)=fc(TEnm).
