Pulse Electronics Corporation introduces an all-in-one combination antenna and proximity sensor package to optimize 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 the 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.
Dimensions for the antenna carrier (X x Y x Z) are 60 x 11.2 x 4.2mm. The proximity sensor footprint dimension (X x Y) is 13 x 8.8mm. The proximity sensor area extends 6mm from the antenna carrier in the Y-dimension and occupies the same volume as the antenna to optimize space utilization in a compact module. During product development design, changes are flexible and easier because only the ProxAnt package needs optimization, and not the main PCB.
“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,” explained Jon Yu, GM for Pulse Electronics Wireless Consumer Business Unit.
