Abstract: | An array of annular slots fed through a radial waveguide does not produce axial radiation when excited through a simple coaxial line. One method of producing axial radiation is to make the excitation cos ? dependent. An alternative method of producing axial radiation is presented, where instead of changing the excitation the slot shape is changed, thereby keeping the excitation simple. |
