Hi!
I'm new at the site and I'm also a beginner in electronics. I start my school project: a GSM jammer. I want to know the bases of the theory for Antennas design and working which is an important part of my project. For the moment, I'm interested to know the frequency response of the quarter wavelenght antennas. I've made my investigations online, but I still have problems to understand what happens exactly in the range : f/10 to 10f.
Thank you so much and I hope you can help me to understand.
