Optimization of a near-field array

We evaluated the performance of overlapped and non-overlapped dual row near-field arrays at 297.2 MHz after optimization both of array circuit and near-field behavior. For a dual row array with overlap that minimizes mutual inductance, it is difficult to achieve transmit performance robustness while maintaining safety in operation, as compared with non-overlapped arrays. Dual row arrays with a small overlap must be carefully investigated before final decisions regarding array design for fabrication can be made.
