Antennas for RF Communications

WE CAN CATEGORIZE RF ANTENNAS INTO RECEIVING TYPES AND TRANSMITTING TYPES. NEARLY ALL transmitting antennas can receive signals quite well within the design frequency range. Some, but not all, receiving antennas can transmit RF signals with reasonable efficiency.

Radiation Resistance

When RF current flows in an electrical conductor, such as a wire or a length of metal tubing, some EM energy radiates into space. Imagine that we connect a transmitter to an antenna and test the whole system. Then we replace the antenna with a resistance/capacitance (RC) or resistance/inductance (RL) circuit and adjust the component values until the transmitter behaves exactly as it did when connected to the real antenna. ...
