You made the concept of Lobes so intuitive to understand. Thank you.

[josephj]

Okay, for real - these explanations are incredible.
I'm learning things out of my expertise (I'm electrical not communication ENG student) and it's fun going through your videos. They're really good.
Keep it up <3

[devilberg]

sir without your vedio suggestion from my senior, my engineering was hell, but now ita easy and interesting

[jamesacosta]

excellent! Ive been watching your videos and it is so easy to understand! The book alone can be confusing, but combined with your lessons, it is perfect! thanks again!

[virendra]

Thank you sir. You deserve appreciation ❣️

[merylkkhfg]

Your explanations are great and easy to understand!

[prasannavamsi]

plz explain more topics in antenna ...ur explanation is amazing ...

[srinaath]

Thank you so much Sir. Your lectures are helpful

[garychap]

In the example, the peak power of the front lobe is marked as 0db at 0 degree. I would have guessed that the half-power (-3db) line was halfway between the Origin and the Peak of the major lobe ... but it was drawn much closer to the Peak than the Origin.

How do I know where the -3db line is? Is the axis of the graph logarithmic ?

Thank you for these videos, they are VERY helpful : )

[sidingfog]

Thank you so much. Your lecture is great.

[mksuman.]

Nice videos i need it..
Carry on ..plz

have a suggestion to make, you can state the purpose of a particular topic when it is explained, nonetheless your efforts are always appreciable.

[romanashaikh]

Very good video to understand but what are that plane ..? ....

[paulscomputerandradio]

You need to start advertising your videos to the Ham Radio community, your views will skyrocket

[motivatingforenlightenment]

in every cases do we assume the angles for major and minor lobes?

[jatingoyal]

Awwsome lectures sir....
Can u pls tell me one thing that are these lectures sufficient for ies antenna syllbus??

[श्री-टघ]

Sir ans plz you have told in previous lecture that omnidirectional antenna radiates only in plan( yx at 1:30) and it doesn't has back lobe but at 1:30 you said that it will have back lobe??

[Chillundaley]

OMG 😱 u threatend me at 7.15 but your explanation was awesome thank you so much for making videos on antenna wave propagation please make videos on electromagnetic waves and transmission lines (EMTL)
