Thank u so much , u are best among all u are doing a lot for us. Once again thank u sir.
Thank u sir,I am inspired by the way of explanation..
TQ u very much sir for explaining good manner 🙂

Super sir! Thank you so much sir ..these videos are very helpful
Your positive comments motivates me, Thanks and welcome 🙏
Super Sir, as always
Your positive comments motivates me.
Teachers like me just wants positive comment from student.
Love from you guys means a lot to me.
My goal is to create largest community of engineers in entire globe. Please help me by sharing this playlist with your friends.
Super, very clear. Could you elaborate the pros & cons of each method ?
Good explanation sir. In comparison method, we can calculate Gaut using two antennas. By keeping reference antenna as transmitting antenna and apply Friis tx eq, we get Gaut = (Pr/(Pt Gt)) x (4 pi R/lamda)^2. Is there any drawbacks with this method.
Nice video,very useful
Good explanation
Keep sharing it with your dear ones
Excellent video...Tq sir..🙏🙏🙏
Thank you for the video. I have one question if I were to use VNA as my transmitter can I use the S21 measurements and take those to be the power received?
Woow...super...
Love and happiness of students is my ultimate goal, God bless you 🙏, keep learning and keep progressing.
Sahi!
Tq sir
excellent explanation sir
your videos are really good and useful specially this video....plzz make videos on sky wave propagation...plzz...my exams are very near....from april ending..
It's there in my AWP playlist
@@EngineeringFunda okk sir...thnkuu soo much
sir please reply what is the distance between two antennas for measuring gain
It can be measured in far field, distance between two antennas should not be placed in near field and reactive field regions.
It can be anywhere in far field for gain measurement.
How will we get 20 and 10 sir? Plz explain
is direct method and comparision method is same
Sir pls upload a video on directivity measurement
Gain measurement can be done.
Directivity is ideal version of Radiation pattern.
K sir tq u
10log(Pr2/Pt1) , 10log(Pr3/Pt2) , 10log(Pr1/Pt3) ?
what r u doing yar u called same word G and another time K , what s this
I have updated this video, Kindly go through playlist of Antenna
ankit bhai zada mt padho paper assan aaega hum tumhare sath hein
Nice explanation
Your positive comments motivates me, Thanks and welcome 🙏
