What is sectorial antenna?

A sectorial antenna is a directional antenna used in wireless communication systems, particularly in cellular networks. It typically comprises a flat, triangular or rectangular-shaped antenna element with multiple radiating elements that are aligned in a specific direction. The sectorial antenna is designed to cover a specific sector of a geographic area by transmitting or receiving signals in a specific direction. Sectorial antennas are widely used in industries, organizations, and residential areas to provide wireless communication, such as voice and data transmission, to devices within the target sector. They are also used in point-to-multipoint wireless communications and can be configured to have multiple sectors to cover large areas. Sectorial antennas are highly efficient due to their directional radiation pattern, which helps to reduce interference and improve signal strength.
