In telecommunications, a billboard antenna, also called a broadside antenna, is an array of parallel billboard antenna antennas with flat reflectors, usually positioned in a line or plane. The spacing and dimensions of the dipoles depend on the wavelength. The main lobe of a fixed billboard antenna may, within limits, be steered by appropriate phasing of the respective signals to individual elements of the array.

Electronics Topics
The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the fields of electronic engineering, and the hardware design side of computer engineering. The study of new semiconductor devices and their technology is sometimes considered as a branch of physics.
