I want to know the answer to the following question:
What is the major thing that sets the size of antennas at lower frequencies?
All the background I'm provided with is that "In addition to a lower radiation resistance, the reactance becomes higher as the antenna size is reduced, and the resonant circuit formed by the antenna and the tuning coil has a Q factor that rises and eventually causes the bandwidth of the antenna to be inadequate for the signal being transmitted.". Is that enough to answer the question?
