Before talking about various types of antenna symbol i would like to describe about antenna. Antennas serve either or both of the following two functions: the generation and the collection of electromagnetic energy. In the transmission system, a radio-frequency signal is developed, amplified, modulated, and applied to the antenna. The RF current flowing through the antenna produce electromagnetic waves that radiate into the atmosphere. In a receiving system, electromagnetic waves “cutting” through the antenna induce alternating currents for use by the receiver.
The list of various antenna symbol are shown below:
