A complete behavioral model of radiation-pattern characteristics of phased array using a novel digital phase shifter

摘要

A complete and behavioral model for radiation-pattern characteristic of phased array has been presented. The model has many input parameters and it has a lot of features, such as parameter simulations with results analysis, unconventional two-dimensional color graph representation capability in order to show more clearly the results. It is an optimum instrument to investigate the performance of a beam-former in relation with an analogue phase shifter, ideal digital phase shifter, simulated real phase shifter and measured real phase shifter. Measured values of three different prototype of the proposed phase shifter architecture have been used in order to study the performances of the same architecture.
