Tags: broadband , waveguide , radiator , antenna array , PAA , polarization Path: Home / Publications / Archives Phased antenna arrays (PAA) of waveguides with complex cross sections are analyzed in this work. Particularly, the analysis focuses on linearly polarized waveguides with dielectric matching units (inserts, covers and waveguide transformers). The study of power and frequency characteristics of these PAA in scanning sectors is included. An optimization method for the design of this kind of arrays in order to achieve broad frequency band and scanning sectors is also presented.
