Abstract

This report, and the code described within it, was written as a part of the project ESGAS, which is financed by the Swedish Defence Material Administration program ÖSTEN. Active phased array antennas are receiving a great deal of attention for their use in both radar and electronic warfare (EW) systems. In the future such an array does not only require a broadband behaviour in terms of apertures, T/R modules, beamforming and beamscanning, but also modular and reconfigurable architectures in order to, instantaneously, reconfigure the array to the required function(s) and other parameters such as effective radiated power (ERP) and beamshape. A matlab 5.3 code has been developed to evaluate some aspects of the performance of microwave components in the feed of an array. That code and the ideas behind it are described. Furthermore the report contains some considerations on (i) the direction of a microwave beam steered through discrete timeshifters and (ii) directivity simulations of an array.
