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 nonoverlapped arrays. Dual row arrays with a small overlap must be carefully investigated before final decisions regarding array design for fabrication can be made
