[0002] A waveguide slot antenna is an antenna that uses slots in the waveguide wall to radiate or receive electromagnetic waves. These slots are typically cut into the waveguide wall in a patterned pattern, which encourages electromagnetic wave radiation. The operating principle of a waveguide slot antenna is based on the Babinet principle: a half-wavelength slot antenna is complementary to a half-wavelength dipole antenna, resulting in a high impedance characteristic. The waveguide, as a high-impedance transmission line, can achieve impedance matching with the half-wavelength slot antenna. When a signal is transmitted in the waveguide, an induced current is generated in the metal waveguide wall. These currents radiate electromagnetic waves through the slots.
