This series on antennas is the best I've found anywhere, please keep them coming! Really unlocking my understanding of some of these concepts I've only read about before. Thank you!!
@ 2:56 With a target-frequency of 5 GHz the wavelength is 0.06 m. Thus, the half-wave dipole antenna is only 3 cm. long. en.wikipedia.org/wiki/Dipole_antenna#/media/File:Half_%E2%80%93_Wave_Dipole.jpg
Is there an easy visual explanation of why an antenna being physically too short for a given frequency is iess efficient, but still able to generate a transmission on that frequency? Maybe a sinewave shown on graph and some kind of pushing force behind the wave (until the element ends, but the wave is still created beyond that point?)
Does anyone know how significant the gap in between the two poles is? For example, how big can this gap get before it has a negative consequential impact on the efficency of the antenna, and what those consequences be, as I assume this gap is included as part of the effective antenna length

Thanks! I'm glad you like the videos!
Just Perfect , Really !
Well, in a short Period of time to give all the necessary information, good Job done!!
Thank you!
Good video!!!
Great explanation
Thank you!
Viva prep done. Thanks ma'am 😁
Thank you!
better than books. thank you
You're welcome! Thank you for the feedback!
Does the charge concentrate at the ends or uniformly over the polar length?

Thanks, can you please explain transmission line model for microstrip antenna
I have a question: Can we connect the two ends of a dipole antenna with a wire which is set up along the dipoles?
Thanks for the lesson!
