Abstract

In the millimetre-wave range, cylindrical dielectric insertions are employed to support a subreflector and, at the same time, as a radome of a dual-reflector omnidirectional antenna. Such a dielectric discontinuity can substantially degrade both matching and radiation characteristics of the antenna. Until recently, the problem of optimization of a dielectric radome was solved experimentally due to a lack of methods that allow the VSWR of a dual-reflector omnidirectional antenna to be calculated taking into account the dielectric insertions. This paper presents a numerical approach to select the parameters of a dielectric radome for a dual-reflector omnidirectional antenna.
