In this paper, a new approach for removing redundant components from reconfigurable antennas is presented. The approach is based on graph models and it minimizes the number of electronic components used. As an example, a reconfigurable U-Koch microstrip antenna is investigated and redundant switches are removed. The antenna is redesigned and the performance of the optimized prototypes is tested and...
This letter investigates a new reconfigurable antenna technique based on the rotation of a slot. The surface currents are redistributed for each slot position. The antenna is simulated, fabricated, and tested. The return loss frequency tuning matches the simulated data. The antenna radiation pattern remains unchanged for different slot positions. Finally, the process for automatic rotation and control...
