Abstract

A system consisting of millimeter wavelength ferroelectric substrate components has been simulated in order to be used to excite a phased array antenna at 26 GHz. This system is used as a beamformer for a point-to-multipoint radio link at the frequency range of 25.5 - 26.5 GHz. The system analysis, simulations and optimizations aim to examine the tolerances of each microwave component and to extract their optimum characteristics in order to achieve the desired excitation currents for the phased array antenna. The present work shows the analysis and simulation steps, in order to prove that such systems are able to produce the desired radiation pattern of the whole array.
