Loop Antennas With Ferromagnetic Core TRIZ Cases

Infinite baluns cancel stray RF currents on coaxial cables, stabilizing radiation patterns and noise rejection across wide frequency ranges.

Segmented magnetic cores expand the antenna volume vertically to improve signal reception without increasing the device footprint.

Half-moon magnetic members shield drive units from external fields, maintaining antenna sensitivity for accurate radio wave timepieces.

Laser ablation reduces copper track thickness below skin depth limits, enabling multiple antenna turns and enhanced inductive coupling.

A thin film antenna assembly mounts between substructure and covering to generate electromagnetic fields.

A flexible circuit board mounted on a support tube forms an antenna loop that operates across a full frequency band while maintaining performance when bent.

Segmented bar antennas use flexible core joints to prevent breakage under impact while maintaining stable communication frequency.

Parallel coils on a magnetic core increase combined inductance, overcoming metallic interference to extend communication distance.

A near field communication antenna module uses a radiation pattern winding around a magnetic body to enable signal recognition on rear and side surfaces of portable terminals.
