Abstract

A new type of microwave antenna radome structure for aircrafts is suggested, which is a waffle radomes that possess improved characteristics if compared to traditional structures. Design peculiarities of such radome walls, waffle structures and their load-bearing elements made of dielectric composite materials are considered. A calculation model for such structures is justified and a methodology of selecting reasonable layer parameters according to radome’s level of radiolucency. A comparison of radio engineering characteristics of waffle and traditional three-layer structures of radome’s walls in a wide range of electromagnetic waves’ incidence angles in presence of mass limitations is conducted.
