hi
i need some info o n resonant antennas.Why call dipole as a resonant antenna?
i read that the impedance of resonant antennas is resistive.But how does it help the antennaa and are they preferred over non-reso antennas?

 

Hello,

Here is a page with some links on antenna theory:

I'm bookmarking this page.

 

thanks a lot!
a query again
what is relation between the input impedance and length of antenna?

 

Hello,

You could take a look at the Neets Series:

Module 10 will cover the antennas.
