SAR Reduction With Antenna Cluster Technique

An efficient and straightforward antenna design method is presented that maximizes the ratio of total efficiency specific absorption rate (SAR). This goal achieved with a multiport cluster technique where several ports are excited collectively appropriate feeding weights. These weights found as an eigenvalue solution formulated in terms radiated near-field power antenna. The relies on both (SAR) far-field (radiation) physics it can be applied to various cases. importance maximization total-efficiency-SAR feasibility proposed approach demonstrated simple multiple-dipole example more realistic metal-rimmed held user’s hand.
