Description of Work: 


Planar antenna structures are well suited to portable communications equipment due to their small size, low cost and ease of integration with associated electronics. The design of these antennas generally requires use of full-wave electromagnetic simulators to include the effects of the conducting and dielectric environment surrounding the radiator. This project will investigate the application of evolutionary computation (EC) methods to the optimisation of antenna structures to achieve the specified design goals, with a view to determining which algorithms work best under various circumstances. This will require tight coupling of the optimiser and electromagnetic simulator to minimise the computational cost in arriving at the optimum antenna design.

Description of Work:

  • Determine the applicability and limitations of EC methods to planar antenna design
  • Develop methods of integrating full-wave electromagnetic simulators with the EC optimiser to minimise the overall computation cost
  • Use this approach to devise new antennas with superior performance characteristics.
