Abstract. An ultra-wideband polyconical antenna with a homogeneous dielectric lens is investigated. As a result of numerical modeling and parameter optimization using the finite element and finite difference methods in the time domain, it is shown that the optimized polyconical antenna provides an operating frequency band of 44:1 with an efficiency greater than 0.8.

Key words: ultra- wideband antenna, omnidirectional antenna in horizontal plane, polyconical antenna, dielectric lens.

Financing: The work was carried out using budget funding within the framework of the state task 0030-2019-006.
