Antenna Coils operate by current flowing through the Transmitting Antenna (Tx), which generates a radiating magnetic field. A current is induced in a receiving antenna (Rx) while in proximity of this magnetic field, developing a signal across the coil.
Quantic ECI antenna coils range from miniature ferrite-wound components for near field (LF & HF) RFID transponder applications, to large self-supporting air coils measuring up to 3 feet in diameter. Ferrite core antennas are typically used for lower frequencies (125kHz & 13.56 MHz are common) and can be designed in various shapes and aspect ratios to optimize field direction and intensity, including 3D for near isotropy. Additional design approaches include reducing capacitance using single-layer windings, Litz wire to minimize high frequency AC losses, Ceramic coil forms for mechanical stability, self-supporting air coils for maximum space utilization, etc.
Antenna applications include:
- Transmit/receive Coils
- EMI detection
- 3-axis field generation coils
- Sensor coils
- Test & measurement
