The results of modeling broadband antennas for surface mounting on metal surfaces are presented. The considered antennas are a broadband excitation node in a dielectric shell in the form of a fragment of a conical waveguide. The simulation was carried out by the method of moments in the FEKO software environment. The frequency dependences of the input resistance, the standing wave coefficient, and the directional pattern are obtained. Comparison of the modeling results of the excitation node and the results of VSWR measurements of the manufactured model are presented. Modifications of antennas with the direction of the dielectric waveguide along the surface and perpendicular to it are considered. The received antennas can be used by telecommunication systems for installation on mobile and stationary objects.
