  • Passive radio frequency energy detector systems and methods
    Patent number: 9939478
    Abstract: The present disclosure provides passive radio frequency (RF) detection systems and methods, which may include various exemplary circuit embodiments, a detection device, and methods associated therewith. The passive RF detection systems and methods provide passive detection of emitted RF energy. In an exemplary embodiment, the passive RF detection systems and methods may include fast switching and low forward-voltage drop diodes, a light emitting diode, a resistor, and an antenna, each of which may be disposed within or outside an external housing or packaging. In another exemplary embodiment, the passive RF detection systems and methods may include a push button switch for selective operation. Advantageously, the passive RF detection systems and methods are configured and operate in a completely passive manner.
