Masts are a common method of deploying basestation- or broadcast-type antennas for mobile communications. Antennas with a mast-like structure usually have a vertical polarization owing to the currents following the vertical metallic mast structure. Horizontal polarization is also of interest for mast-like antennas but is difficult to realize. This paper presents a design concept for a mast-like antenna structure that can give horizontal-polarization with simple azimuthal beam selection capability. The mast-like structure comprises identical isosceles triangular waveguides arranged in a cylinder. The slot elements are located on the outward-facing wall of each of the triangular waveguides. Different configurations for the slots are chosen based on the apex angle of the triangular waveguide, which in turn depends on the required number of azimuthal beams. Design examples with different angular coverage are demonstrated using simulation. We include an adaptation of the design for a surface mounting form, using half of the mast-like cylindrical form.
