Loop Antennas With Ferromagnetic Core TRIZ Cases
- Coil Antenna Layout Around Magnets Without RF Loss
A non-overlapping magnet and coil layout preserves coil RF performance while avoiding added device width in compact electronics.
- Segmented Magnetic Core Antenna With Lateral Bridge Sub-Cores
Lateral bridge sub-cores stabilize magnetic coupling between segmented core parts, reducing sensitivity to temperature and contact pressure.
- Multi-PCB Antenna Layout for Stronger MST Magnetic Flux
A third PCB links printed antennas into a closed mutual-induction circuit, expanding MST recognition area without needing more mounting space.
- Side-Wrapping NFC Antenna Layout for Dual-Side Card Detection
A side-wrapping NFC antenna extends from the back to the edges, enabling front and rear card swiping while avoiding screen and battery interference.
- Wireless Charger Thermal Path for Sealed Heat Dissipation
A heat-conductive path from the top cover to a metallic case dissipates fast-charging heat while keeping the charger sealed against water and dust.
- Wireless Charging Resonator With Human Body Detection Antenna
A separate antenna senses second-frequency impedance and phase changes to distinguish human bodies from metal during wireless charging.
- Flexible Wire RFID Tag With Helical Antenna Grip
A deformable helical wire antenna expands to fit objects, then contracts to grip them for more robust RFID tagging and theft detection.
- Foldable Antenna Coil Layout for Extended Wireless Range
A two-coil series layout across foldable housings extends short-range antenna operation and keeps wireless performance stable in folded states.
- High-Permeability Antennas for Stronger Catheter Position Sensing
External high-permeability antennas concentrate magnetic flux to boost catheter position sensor signals without increasing diameter.
- Passive Stylus Resonance Circuit for Noise-Resistant Touch Sensing
A resonant passive stylus and conductive blocking member cut eddy-current noise, improving touch sensitivity near conductive objects.
- Multi-Layer Coupling-Controlled Antenna for Longer RFID Read Range
Ferrite-coupled helical antenna layers extend RFID and biochip read range while reducing energy loss and improving data transmission.
- Low-Profile Vehicle Antenna Layout for LTE and 5G Bands
A segmented loop antenna with coupling feed and integrated heat dissipation supports broad LTE and 5G bands in tight vehicle mounting space.
