I am reading about antenna design and have a few questions which I could not get clarified.
I read about "Stubs". I got to know that Stubs are used for impedance matching of an Antenna either by leaving it as an open circuit in one end or as an short circuit.
Question - How to find the input impedance of an Antenna of a particular length? Is there any method and how to calculate the stub length? Is there any formula?
Would really help me if someone could provide an example for calculating the input impedance of the antenna and the stub length for impedance matching
