A Study on Reconfigurable Antenna Array Feed Networks Using Distributed Switched-Line Phase Shifters for mm-Wave Operation

Lead Research Organisation: Queen Mary, University of London
Department Name: Sch of Electronic Eng & Computer Science

Abstract

The primary aim of the research is to design a passive high-gain planar mm-wave antenna which can be electronically scanned in two dimensions by reconfiguring the array feed network. In addition to this, the research aims to implement a design which could be realised using phase-change materials to minimise the insertion loss and size of a switch-line phase shifter, which is suitable for use in an antenna array feed network (this is fundamental to increasing the operating frequency well into the mm-wave bands). Finally, the research also aims to reduce the complexity of configuring the antenna array by developing a machine learning algorithm to assist with the array design incorporating the switched-line phase
shifters.

The research aims to answer the following questions:

1) What benefits can be offered by distributing phase shifters throughout the array feed network rather than at each individual element?
2) Can phase-change materials facilitate sufficiently low-loss RF switches at mm-wave frequencies suitable for a reconfigurable antenna feed network?
3) Can a machine learning algorithm enable a reduction in the complexity of a large dual-scan array configuration by reducing the number of redundant phase states?
