Keywords:coaxial line, Green’s function, circumferential slot, near-field, field components
AbstractThe problem of determining the electromagnetic fields, created by slotted coaxial line, is solved in the present work. To determine the coaxial-slot antenna near-fields the Kirchhoffs method has been applied. Electromagnetic field distributions in the near-zone of coaxial-slot radiator have been explored for different values of feeder parameters on a large range of wavelengths. Field diffraction patterns for the short distances from the slot radiators have been obtained.
