[0002] An antenna is a device used to receive and send radio waves. Its function is to convert radio waves into electrical signals or convert electrical signals into radio waves. Antennas are widely used in fields such as wireless communications and broadcasting. The horizontal polarization of an antenna means that when the antenna transmits or receives electromagnetic waves, the electric field vector of the electromagnetic wave oscillates in the horizontal direction. Horizontally polarized antennas usually have the best transmission and reception performance in the horizontal plane and are suitable for scenarios where signal transmission in the horizontal direction is required, such as radio and television broadcasting. Horizontally polarized antennas play an important role in the transmission and reception of electromagnetic waves. Vertical pitch refers to the angle adjustment of the antenna in the vertical direction. Vertical pitch can be used to adjust the radiation range and reception range of the antenna to adapt to different communication needs and environmental conditions.
