Tunable antennas and band gap surfaces

• LC tunable antennas at low frequencies are lossy • Reconfigurable antennas need matching circuits • MEMs switches — optimise bias configuration • Tuning bandwidths look promising — DVB-H achieved • Variety of different tuning mechanisms • A universal matching circuit is a goal • Reconfigurable antennas, FSS and EBGs are feasible • Tuning bandwidths look promising • Variety of different tuning mechanisms
