Loop Antennas With Ferromagnetic Core TRIZ Cases
- Symmetric Multi-Layer Antenna Coil for High-Density Plasma
A rotationally symmetric multi-layer coil evens voltage distribution to limit CCP window damage while sustaining high-density plasma.
- Nested Helical RFID Antenna for Compact Long-Range Biochips
Interleaved helical windings and ferrite coupling extend RFID recognition distance while keeping the antenna compact enough for biochip integration.
- IC Card Antenna Coil Layout for Stronger Magnetic Coupling
A two-part coil around a magnetic through hole boosts IC module coupling while limiting field cancellation and inductance loss.
- Antenna Base Mounting Structure for Chip Positioning Stability
A base-side recess and protrusion create a mounting space that prevents chip shift during reflow and preserves terminal connection.
- Roof Antenna Cover With Locator Light for Parked Vehicle Finding
A roof-mounted locator light in the antenna cover helps drivers pinpoint a parked vehicle when sound cues and standard lamps are hard to detect.
- Antenna Package Ground Layout for Low-Loss Display Signal Transmission
A selective ground-layer overlap layout cuts radiation disturbance and signal loss in high-frequency display antenna packages.
- Antenna Module Coil Layout for Flexible Booster Coil Redesign
A separate magnetic sheet with a second coil lets antenna modules redesign the booster coil later while extending communication distance.
- Antenna Module Shielding Layout to Prevent Magnetic Saturation
Anti-overlap holes in the shielding sheet stop magnet-induced saturation, preserving wireless charging efficiency and reducing heat.
- Adjustable Conductive Pattern Contact for Multi-Product PCB Integration
A bendable contact portion lets one conductive pattern fit different PCB contact positions, cutting redesign effort, space use, and material cost.
- Antenna Package Ground-Via Layout for High-Frequency Signal Loss
Ground-layer vias around antenna feed wiring cut FPCB-related loss and disturbance, improving high-frequency radiation efficiency and reliability.
- 3D-Coil Transponder Structure for Shorter Wire Length and Lower Loss
Separated lead molding removes plastic under the magnetic body, shortening 3D-coil wire paths to cut loss and transponder size.
- Wireless Charging Cover Resonator Structure for Higher Coupling
A ferrite and metal layered cover resonator raises coupling and tunes resonance to improve wireless charging efficiency.
- Coil Antenna Resonance Tuning for Harmonic Wave Suppression
Parasitic capacitance in a supported coil antenna forms a resonant band-stop filter that damps harmonics without increasing vehicle antenna space.
- Combo Antenna Module Gap Layout for Compact NFC and MST Performance
Adjusting the gap between stacked magnetic sheets preserves compact combo antenna performance while reducing wireless charging noise.
- Multi-Coil Underground Transmitter for Wide-Frequency Drilling Signals
Switchable coils with different inductance let one underground transmitter span 0.3-50 kHz, avoiding transmitter changes during drilling.
