Sir,u have to also explain why this phonemenon is happening ,like what the importance of imaginary plane,current and charge distribution according to time..every lecture I got too many confusion.
Excellent explanation
Your positive comments motivates me, Thanks and welcome 🙏
Thank you for knowledge on antenna fundamentals
Is the telescopic antenna of a regular FM radio a mopole antenna? If you have a receiver with an antenna connector with two poles, such as a 3.5mm jack, does virtual ground mean that you do not have to connect the other terminal anywhere, for example to the physical ground?
Thank you sir

Your positive comments motivates me and person like me get boosted by my students feedback. Thanks and welcome 🙏
Can you please get us research papers on antenna?
sir please guide about current distribution in dipole and mono dipole ..
Sir pls suggest how to test with network analyser for monopole antenna Iam getting higher swr
can you explain how virtual monopole is formed?
It is as per imaginary ground concept
Lower Radiation Efficiency than a Dipole means a low angle of radiation?
Nope, you can say low radiation resistance
sir can you add sleeve dipole
Please explain why are you assuming that
In small monopole antenna (H less than lamda/10), if we add capacitive load at end of monopole, I think input impedance will became small and it will be like that Za=Ra -jX , Is it a correct answer or am I wrong? if i am wrong, can you guide me with explain?
It won't decrease ma'am. Specially because the magnitude of the impedance will be √(R²+X²). You've written it in the complex form.
