  • This video was made for a junior electromagnetics course in electrical engineering at Bucknell University, USA. The video is designed to be used as the out-of-the-classroom component and combined with active learning exercises in class. This video covers some of the terminology and equations that engineers use to define the properties of antennas.

    Thank you for this! I've been reviewing my antenna notes from 3 years back (from another university) and your videos are just awesome! You clearly explained the concepts for easy understanding!

    Dear Professor Kridnix, I have to say you are genius, I read the textbook for 3 times but still don't completely understand it, but only watch your lecture 1 time, 1 completely understand everything, thank you so much professor.
    By the way, would you please post all of the lectures related to Transmission Line, we all really need them to enhance our understanding. (or can you please give us the link to all of your lectures related to Transmission Line)
    Thank you so much, best wishes to you Professor Kridnix

    Thank you so much. I wish everyone teach this topic could teach like you. In your voice and explanation, one can really tell that you are passionate about teaching your students. This attitude is missing in a lot of professors today, especially here in America and yet students pay a lot tuition and other fees for University. But thank so much for passing on this wonderful knowledge. God bless you.

      I watched this video several times and loved the clarity ,explanation, mathematical treatment, graphs and equations of electromagnetism radiation. It helped me enormously in revision and career development/progression in radio/electronics communications.
      I am looking forward to complete all videos. Thanks alot.

    Hi ! Nice video!! I want to ask you... if I only care about the receiving signals (don’t care about transmitting) would I have to prefer a high dbi antenna or a medium?? Is higher dbi antenna more sensitive to receive??? Thank you in advance

    The linear scale radiation pattern @15:00 seems wrong. I think 0 and 90 are interchanged

    How do you find the reactance of the antenna?

  • @PaulMarostica
    @PaulMarostica 2 ปีที่แล้ว

    Maybe normalized radiation intensity, F, stands for fraction, because it is the fraction you multiply the maximum radiation intensity by to calculate the radiation intensity.

  • @nonsocheazzoscrivere
    @nonsocheazzoscrivere 9 ปีที่แล้ว +1

    This is a very good explanation,but i have a question: the normalized radiation Intensity of the dipole is sin^2(theta),and then we plot theta in the radiation pattern.
    Now,the plot says that we reach the maximum with theta=0,but with sin^2(theta) we have the maximum when theta=90 degrees.
    Where is the mistake?

    • @nonsocheazzoscrivere
      @nonsocheazzoscrivere 9 ปีที่แล้ว +1

      ***** First of all thank you for the answer.
      My problem is that i cannot understand the relation between the normalized radiation Intensity of the dipole, sin^2(theta),and the polar plot.

    • @lolalafnegal
      @lolalafnegal 8 ปีที่แล้ว

    • @mohitkhajuria4623
      @mohitkhajuria4623 8 ปีที่แล้ว

      +reham briek theta in (sin (theta))^2 is the angle that varies from 0 to pi which is as per the convention of regular spherical coordinate system. While theta in antenna pattern/plot is the angle that is measured with respect to normal axis to antenna . they are slightly different , by mistake he has called both anglesby same name.

    directivity in last slide is wrong. D= max(s) / (Prad/4pi*r.^2). instead of !=max(s) / (4pi*r.^2/Prad). pls note that.
