What will you be doing?
Wide angle scanning phased array antennas are widely applied in radars and communication (SATCOM, 5G, etc.) systems. One of their main design challenge resides in the performance degradation due to two main effects: a reduced aperture projected in the scanning direction and mismatch caused by the dependence of the active input impedance on the scanning angle. A solution to this problem is to combine the phased array with a dielectric lens. The mismatch is solved by operating the array in phasing configurations limited to the cases in which the array is matched. Moreover, the current distribution over lens can be controlled by properly defining the phase distribution over the array, thus allowing to illuminate a wider area and then increase the directivity for wide scanning. The main drawbacks of this solution are the size and weight of the lens which might make it unpractical in several applications where small volumes and low weight are crucial issues. In past few years, several activities have been carried out at TNO with the goal of minimize the lens volume and weight and a few novel lens configurations have arisen as promising solutions.
The main goal of this project is to enlarge the scanning range of a phased array by combining it with a dielectric lens to cover a (quasi-)hemispherical scanning range. The proposed solution is to study a low profile integrated lens made of a single or several materials with a scanning of at least 80° in all scanning planes.
