Slot

A type of antenna that utilises a slot or gap cut into a conducting surface to radiate electromagnetic waves. The slot acts as the radiating element, functioning as an inverted version of a dipole antenna - where a dipole has two rods separated by a gap, a slot antenna has a gap in a continuous surface. One of the main advantages of slot antennas is their ability to be integrated directly into the surface of a device or vehicle, making them an attractive choice for applications where space or aerodynamics are critical considerations. Despite their compact design, slot antennas can achieve good radiation efficiency and are often used in applications such as radar systems and satellite communications.
