Theory Behind Everything
Let’s start with the basic structure. The antenna is a part of a system that conveys RF energy from a transmitter to a receiver. The system as a whole is quite complex, and includes many parts: the transmitter, the method of feeding RF energy to the antenna, the antenna, the signal propagation path from the transmit antenna to the receive antenna, the receive antenna, the means of feeding RF to the receiver, and finally the receiver.
