Abstract
This paper presents the analysis and design of a simple conical beam antenna using circumferential aperture beside the radial waveguide near the reflector for vertically polarized radiation. The structure of the antenna is composed of two circular plates that are parallelled to each other in horizontal plane. The vector potential approach is used to calculate the radiation properties. The radiation characteristics such as radiation pattern, elevation beam peak, half power beamwidth and maximum directivity of the antenna are analyzed. The contour plot of elevation beam peak and directivity as a function of the radius of the circular plates and the spacing between the radial waveguide and the reflector are illustrated as the guideline for the design criterion of a conical beam antenna using circumferential aperture beside the radial waveguide near the reflector for vertically polarized.
