FAQs for Antenna Coils and Sensor Coils
What types of antenna coils does ECI manufacture?
ECI manufactures a comprehensive range of custom antenna coils for mission-critical applications, including SMT transponder coils (AS Series), 2-D and 3-D transponder coils, and Z-axis antenna coils. Our antenna coil products range from miniature ferrite-wound components for near field RFID applications to large self-supporting air coils measuring up to 3 feet in diameter. We specialize in custom electromagnetic components designed for aerospace, defense, security, medical, and commercial applications.
How do antenna coils work in RFID and sensing applications?
Antenna coils operate through electromagnetic induction. Current flowing through the transmitting antenna (Tx) generates a radiating magnetic field. When a receiving antenna (Rx) is positioned within proximity of this magnetic field, a current is induced in the coil, developing a signal. Ferrite core antennas are typically used for lower frequencies like 125kHz and 13.56 MHz, and can be designed in various shapes and aspect ratios to optimize field direction and intensity, including 3D configurations for near isotropy.
