Hi Guys,(adsbygoogle = window.adsbygoogle || []).push({});

I looked so hard on the net, trying to understand something that I am struggling with for the whole day, but I ended up frustrated.

I am working on my design project and was assigned a part conecnred with antennas, I am using the Antenna Theory Analysis and Design by Balanis to have basic understanding of antennas,

What is confusing me is when he talks about the AC being applied across two conductors connected to an antenna. He choses different locations of the conductors and assign to them different charges (+ve) and (-ve) given at a specific time.

How can this happen, I always thought that AC means a constant current and volatge distribution, at a spcific time, along the transmission line. That is, for time t1, measuring the voltage at 2 meters from the source will yield the same result as when we measure it at 5 meters(at least this is what I thought)

AC, as I remeber, is a changing current and voltage with respect to time, NOT displacment..

Please enlighten me :(

Thanks in Advance
