An antenna is generally composed of a radiating element, a balanced feeder, a reflector, a feeding network, connectors, and other components (omnidirectional antennas usually do not include a reflector).

The primary function of the radiating element is to convert electrical current energy into electromagnetic energy and radiate it, or to receive electromagnetic energy and convert it back into electrical current energy.

An antenna is usually formed by arranging one or more basic radiating elements in a specific geometric configuration, such as 1×2, 1×4, 1×8, 2×8, and so on. Radiating elements come in various shapes, which are mainly divided into two common categories: linear elements and microstrip patch elements. In antennas, linear elements are typically half-wave dipoles, meaning that the total length of the dipole is approximately half of the wavelength at the antenna’s center frequency, with each arm being about a quarter wavelength long.
