Adaptable Reconfigurable Antenna Array System with Multi-Angle and Tri-Polarization Diversity [Education Column]

A reconfigurable antenna system is proposed here that aims to find the best communication link with respect to power. The system consists of two arrays: one on the transmitter side and one on the receiver side. Both arrays were developed using microstrip transmission-line technology. The frequency of operation was (as required) 2.4 GHz, and was supplied by ZigBee chips. Each ZigBee chip was connected to a personal computer to facilitate power measurement, and hence determine the best communication link possible.
