Software defined antenna

The aim of this work was to investigate the feasibility of a single re-configurable structure comprising multiple radiating sections, described as a ¿Software Defined Antenna.¿ These sections would allow the frequency of operation, polarisation and radiation patterns to be varied to suit different radio systems. In addition, with multiple input feeds, simultaneous operation of several radio systems could be achieved from the one unit. This in turn could lead to a reduction in the number of installed antennas on a given platform. A concept demonstrator for a `Software Defined Antenna' containing multiple radiating sections, has been designed, modelled, constructed and tested.
