Radiation Patterns (Isotropic, Directional & Omnidirectional antenna) Explained

Radiation pattern of isotropic, directional & Omnidirectional antenna is explained by the following outlines in a unit of Antenna Parameters:

1. Radiation Pattern of Isotropic Antenna
2. Radiation Pattern of Directional Antenna
3. Radiation Pattern of Omnidirectional Antenna

in Directional antenna i have explained following basic terms
a. HPBW (Half Power Beam Width)
b. FNBW (First Null Beam Width)
c. Major Lobe
d. Side Lobe
e. Minor Lobe

I think this is the best intro series out there for antennas. Thanks for making this! I will recommend it to new students.

[AdarshKumar-tmpb]

Thank you so much for this video series sir....it's very helpful for 3rd year EC b.tech students

[venkatesh]

Because of u I had completed AWP, ANALOG COMMUNICATICATIONS, DC, MICRO WAVES thank you very much sir u saved my b tech life

[madhusudanck]

I was pass my antennas and wave propagation subject by your video lectures .Thank you sir

[abfantube]

...pro..sir it is best leacture ...i do t want to think my enginnerng life without enginnering funda

[anuragrajput]

Thank uh sir for such a precious knowledge,
It helped me a lot, keep it up

[atkuriajaykumar]

thankyou very much sir for sharing of your knowledge.You are teaching way better than our lecturers in college

[abfantube]

Thank u so ...much prof...the leacture is best ....i got A+....grade because of u....

[askmea]

Please add a video on radiation mechanism of single wire, two wires and dipole and current distribution of thin wire antenna., bw you explain very well. Highly appreciated

[TechnicalCEO]

Good to see you back sir, wish you a very good healthy life ahead. Thank you for helping me in my engineering journey
