Electromagnetic power transportation using a smart antenna array

A novel antenna loop array design algorithm is proposed for electromagnetic power transportation applications. The proposed method works to maximize coupling between the transmitting array and the receiving loop antenna. The scattering matrix of the loop array in addition to the receiving loop is computed using a full-wave simulator. The magnitude and phase of the excitation coefficients are determined by a set of matching networks feeding the transmitting elements in the loop array and the receiving loop element by a circuit simulator. All coupling has been optimized within the MF and HF bands, with the maximum frequency at 10MHz. Preliminary results show minimum losses of -5dB at 5m. The matching networks can be tuned adaptively for a dynamic environment or to couple power to a moving loop.
