Switchable shield elements beneath a transmission line let engineers tune impedance and phase shift in real time without changing line geometry.

An electrode-array reconfigurable surface redirects electromagnetic waves for blind-spot coverage while reducing modulating-medium thickness and cost.

Integrated capacitor placement between upper and lower circuit bodies shortens wiring paths and lowers inductance in power conversion modules.

A grounded conductive plane above a microstrip trace cuts crosstalk and EMI while preserving PCB routing efficiency and stripline-like signal integrity.

Mounted components placed between solder balls and solder portions preserve impedance continuity, improving signal integrity while reducing routing area and cost.

An EBG structure around an antenna array suppresses surface waves, cuts front-to-back ratio by 6-8 dB, and preserves spacing efficiency.

Switchable shield elements and shunt/series switches let one transmission line tune impedance and phase shift across changing circuit needs.

Larger land electrodes over the coil opening buffer solder ball diameter variation, helping stabilize magnetic flux and board performance.

Separate PCBs isolate cable ends and connector pins, enabling easier rework, segment testing, and stronger signal integrity.

Variable ground opening sizes at signal joints and lines help a wiring board preserve RF resonance and reduce impedance loss.

Hollow regions and locally thinned signal lines cut skin resistance and transmission loss while preserving adhesion in high-frequency substrates.

Adjusting reference plane voltage after PCB manufacturing helps match line impedance, improve high-speed signal quality, and reduce common mode noise.
