axial slot, circular waveguide, electromagnetic waves, radiation, slot antennasAbstract
The scattering problem of electrically long axial slot cut into side surface of the circular waveguide has been considered. Expressions of external self-admittance and transfer conductance were derived. The possibility of creation of a field distribution on the slot forms radiation pattern with low side lobes was shown.References
