Abstract

A novel design of spiraphase-type reflective phased array is proposed. A full-wave mathematical model is developed to predict the scanning characteristics of this phased array. Numerical optimization of the geometry of the array element is performed. The scanning characteristics of the phased array with optimized elements are calculated. It is proven numerically that this passive array demonstrates a total loss better than -2 dB in the frequency band from 25 to 30.5 GHz within a scanning sector limited by elevation angles up to 28 degrees. The mathematical model developed has been experimentally verified with the help of the waveguide simulator.
