Good explanation
Thank you sir
All the subjects playlist of Engineering Funda is available in comment section. Share it with your friends to support us.
Your positive comments motivates me and person like me get boosted by my students feedback. Thanks and welcome 🙏
Gud explanation
Nice
sir , why are we translating spherical waves to planner wave in lens as transmitter and again we are translating those planner waves to spherical waves in lens antenna as receiver . Instead why can't we send those spherical waves directly from transmitter to receiver ? please do reply sir . thank you
If you send spherical waves then with respect to distance area covered by wave will increase that will make signal weak for longer distance communication.
@@EngineeringFunda oh okay , thak you sir got it😀
Sir pls could you explain about
1. Reconfiguration of active and dielectric antenna
2. Antenna test range
Bro can you please elaborate mathematical derivations for these topics then,100%of topics would be covered easily....
Please make a video on directivity of radiation pattern
It is there in my playlist
nice
want more info about zoning and geomtry of non metallic dielectric lenses
Noted ✅
@@EngineeringFunda is it available sir
Plz make a video on Biconic antenna
Sir please explain current distribution for thin wire ,linear dipole and two wired transmission line.
Please add some videos on waveguides
It is there in my microwave playlist
Zoning and tolerance of Lens antenna
👍👌👌👍👍👍👍👍👍
Also explain about tolerance of lens antenna
Substrate integrated waveguide
Derive the derivations also plz
sir please hindi me samjaiye, english me doubts rahete hai or thik se samaj nahi ata. Thank you.
I don't know hindi properly
I need zoning of lens antenna fastly
good explanation
Your welcome
Please make a video on zoning in lens antenna
