SAR with High Isolation and High F/B Ratio

FWT antenna elements are a good choice for reducing unintended electromagnetic radiation, given their superior efficiency, directivity, and high isolation. Reduction of unintended radiation is highly desirable in multiple transceiver co-location, repeater size and performance, and increasingly important in the cellular handset market. Recent regulation by the FCC is designed to reduce the specific absorption rate (SAR) in human subjects during hand held telecommunications, and this trend will likely continue.

Bird's Eye View of the broadcast power shape from a low EMI, and reduced SAR cellular band FWT antenna. The blue colored area denotes extremely low energy levels. Inside, the dielectric embedment elements efficiently convert electrical signals into broadcast power! FWT technology's 3-D antennas reduce energy levels transmitted to the user. FWT designs can transform your product by reducing the SAR and antenna size at the same time.

The yellow colored area denotes low energy levels at a customer-specific location. FWT technology is mature, readily modeled, and available as a connectorized antenna or a complete integrated assembly.
