Abstract :
The phased array composed from spiral microstrip radiators is considered. This array can be applied as radiation focusing spiraphase lens. The lack of traditional phase shifters ensures good cost, technological and constructive characteristics of spiraphase arrays in a microwave range. This device permits to realize a focusing of antenna feed field by a microstrip antenna array. The mathematical model is obtained by integral equation method. The numerical results can be used to develop antennas with optimum parameters.
