In broadcast engineering, a panel antenna is a directional antenna that is widely used to obtain a wireless Internet connection. Directional antennas receive and broadcast a signal in only one direction, resulting in better signal quality. Panel antennas, for example, are used in underdeveloped countries to improve the range and functionality of wireless Internet networks. A panel antenna is shaped like a panel and is typically fixed on a mounting bracket on the exterior or inside of a building. It can also be mounted on a swivel mount, allowing the user to adjust the antenna for optimal signal reception. This type of antenna is usually one-directional, with less mobility side-to-side and up-and-down than an omnidirectional antenna, which can swivel and entirely change its location.
