Alternating Current Sensing Slot Antenna

Dual operations of AC current sensing and Bluetooth transmission using a reconfigurable slot antenna are described here. The novel setup comprises tunable connected to transformer AC/DC converter create smart mechanism. consists double-layer on thin, flexible substrate with tuning circuit consisting capacitive-coupled biasing tracks the backside. Capacitive coupling isolates circuits at DC while providing connectivity radio frequency (RF). Tracks act as capacitors for circuit. A double-sided copper clad Mylar is etched produce one side inexpensive Varactor diodes other side. tunes over wide range approximately 2:1. able sense currents by response when system. can also detect operational or non-operational states appliances devices. This low-cost assist in detecting power monitoring household electrical devices an energy-efficient solution operating transmitter via Bluetooth. measured reflection coefficients radiation patterns good agreement simulated results noticeably clear achieved.
