Microstrip Antenna with Narrow Patches for Wireless Power Transfer

Parallel plate capacitors are introduced for efficient wireless power transmission (WPT). The device is similar to a microstrip antenna except that the width of the patches is much smaller than that of a conventional microstrip antenna. In the proposed system, magnetic field plays an important role for coupling between transmitter and receiver. The proposed WPT device gives a good transmission efficiency with a compact structure in addition to an easy design/fabrication procedure.
