Inside Wireless: Waveguide

In this episode of Inside Wireless, you'll learn everything you need to know about Waveguide - what it is, what shapes of a Waveguide do we usually use in which applications and how they differ from Coaxial Cables.

A Waveguide is a type of transmission line, like a coaxial cable. It allows electromagnetic energy to travel through it and transport it from point A to point B. It is a hollow metallic tube and can have various shapes: circular, single ridge, double ridge, elliptical or rectangular. The size of the Waveguide is determined by the frequency we want to use. The lower the frequency, the larger the Waveguide is.
Unlike coaxial cables, Waveguides work as high pass filters. They do not let low frequency electromagnetic waves travel through, below what is called a Cutoff Frequency. Above this frequency, signal travels freely in what is known as the first Transverse Electric mode.
Coaxial Cables always suffer from higher losses than Waveguides. Another advantages of Waveguides are external noise immunity and high mechanical durability.
Waveguides are particularly useful in high-power applications or whenever a very low loss is beneficial.

If a filter stops both high and low frequencies at different cut off, it's a band pass filter.

should reupload the video for such a mistake

Nice, answered my question in 2:17. Thank you for the short but very informative video

[@ElectronicsCuriosities]

Hi nice explanation 👍🏻😍👌🏻 also explain types of modes in waveguide TE TM and TEM

[@hamdaniyusuf_dani]

I think you get it reversed. A low pass filter passes low frequency. It's also called high stop filter.
If a filter stops both high and low frequencies at different cut off, it's a band pass filter.

Hi Hamdani, thanks for noticing the mistake! We put the correction in the pinned comment below the video.

Hi I have a question
how con I choose the best frequency for my power beam m5-400 25dbi ?? pls help and thanks for your videos

[@Rfelements]

Hey there. You should first do a spectrum analysis in your radio and select the less congested channel. Thank you!

When its operating in the complex way and its no longer usable thats the thing they dont want you think about

w/g behaves like HPF
