  • Abstract
    The radiation field of a coaxial waveguide having a quarter-wavelength choke is determined numerically. It is shown that, similarly to the case of a circular waveguide, the introduction of the choke lowers both the side and back radiation and improves its crosspolarisation and the gain factor.
