Wireless control of reconfigurable antenna arrays

We developed a system that allows a user to wirelessly control reconfigurable antenna arrays using software. The array consists of four coplanar folded slot antenna elements and its different states can be activated or deactivated remotely on-demand to alter the entire array´s resonant frequency. The array alters its operating frequency by changing the status of eight couples of p-i-n diodes simultaneously (four diodes per antenna element). The control system is described and the performance of the reconfigurable array was measured and discussed.
