Proximity sensing antenna

Proximity sensing antenna systems include two metallic antenna arms. One antenna arm is connected to an RF transmitter at a radio frequency (RF) feed port, and the other antenna arm is connected to an RF detector (e.g., RF measurement receiver or RF power detector) at an RF sense port. The metallic...

More Information
Summary:Proximity sensing antenna systems include two metallic antenna arms. One antenna arm is connected to an RF transmitter at a radio frequency (RF) feed port, and the other antenna arm is connected to an RF detector (e.g., RF measurement receiver or RF power detector) at an RF sense port. The metallic antenna arms are symmetrically positioned with respect to each other across one or more symmetry axes. The metallic antenna arms can be implemented as inverted-L antennas, dipole antennas, inverted-F antennas, and/or as other antenna arm configurations. Further, the antenna arms can be dimensionally identical and positioned symmetrically about one or more symmetry axes. The antenna system can be used within proximity sensing devices for a wide variety of applications including low power sensing and can also be used for wireless data communication.
