## Abstract A novel structure of arrayedโwaveguide grating (AWG) multiplexers with a gradedโindex freeโpropagation region (FPR) used to increase the wavelength pass band is presented. The 1โdB and 3โdB wavelength pass bands increase with the increase of the gradedโindex FPR length. Flat and broaden

## Abstract A radial guide field matching method (RGFMM) is used to analyze a circular array antenna consisting of one active monopole surrounded by a concentric array of passive monopoles terminated in arbitrary loads. An equivalent admittance matrix for this antenna system is determined to study
## Abstract An equivalent unit cell waveguide approach (WGA) is described to study the behavior of a multilayer reflect array of variableโsize patches/dipoles. The approach considers normal incidence of a plane wave on an infinite periodic array of identical radiating elements and introduces an equ
