Pulse Electronics has integrated a multi-band antenna and proximity sensor in to a single package. This combination optimizes the characteristics of both functions, thus enabling better device performance and increased design flexibility for tablets, laptops, and notebook computers. The ProxAnt TL 1.0 is a seven band main antenna, a proximity sensor chip, and all needed components included on the same flexible circuit board. Without requiring physical contact, the sensor recognizes when it is close to the user and sends a signal to the host processor to reduce the transmission power to the antenna, thus lowering SAR. The sensor also recognizes movement to avoid a false trigger.
The ProxAnt optimizes the antenna and proximity function as one entity, instead of separately. This integration minimizes the combined size and simplifies logistics to give the best possible antenna performance. During product development design changes are flexible and easier because only the ProxAnt package needs optimization, and not the main PCB. This antenna supports WiFi WLAN 802.11n, ac standards, all LTE bands, and is SAR compliant.
