Waveguides TRIZ Cases
- Polarized Waveguide Filter With Independent TE10 and TE20 Tuning
Protrusions on a rectangular cavity resonator shift TE10 and TE20 frequencies differently, enabling targeted attenuation poles and stable pass characteristics.
- Coplanar Waveguide Step Structure for Wi-Fi 6 Impedance Matching
A stepped coplanar waveguide with a rectangular groove and enhanced grounding improves Wi-Fi 6 band impedance matching and lowers S11.
- Dielectric Waveguide Transition With Offset Plates for Low-Loss Coupling
Offset conductive plates couple circuits to a dielectric waveguide, cutting high-frequency attenuation while enabling wider bandwidth.
- Coplanar-to-Via Transmission Line for Lower High-Frequency Return Loss
A coplanar line paired with a two-conductor via structure cuts high-frequency return loss across substrate surfaces.
- Optical Modulator Layout With Displaced Ground Plane for RF Speed Matching
A laterally displaced ground plane helps Mach-Zehnder optical modulators match RF and optical speeds while limiting cross-talk and distortion.
- Beaded Bellows Coaxial Waveguide for Low-Loss Qubit Interconnects
Bellows-shaped coaxial waveguides with crystalline dielectric beads cut signal loss and raise Q for superconducting qubit interconnects.
- Slotted Reference Conductor Filter for Absorbing EMI Noise
Impedance units on a slotted reference conductor absorb specific-frequency noise, reducing EMI and RFI in high-speed signal paths.
- Overlapping Ridged Waveguide Coupling for Compact RF Connections
An overlapping ridged waveguide creates capacitive coupling without separate connectors, saving space while maintaining RF signal transmission.
- Waveguide Transition Circuit Layout for Low Radiation Loss
Opposed electric-field orientation in a waveguide transition circuit cuts radiation, reflection, and conductor loss across high frequencies.
- Terminated Waveguide-to-Coaxial Converter for Wider Bandwidth
A terminated waveguide section extracts high-order modes near the probe, improving impedance matching and widening converter bandwidth.
- Marchand Balun Slot-Line Layout for Compact 100-140 GHz Multipliers
A slot-line Marchand balun shrinks frequency multiplier layout while sustaining signal balance and output across 100-140 GHz bands.
- Dielectric Waveguide Bundle Materials for Low-Crosstalk mmWave Links
Different core and cladding dielectrics guide millimeter-wave signals with lower crosstalk, better integrity, and dense high-data-rate links.
- Coaxial Transmission Line Tensioning to Prevent Inner Conductor Deflection
Linear actuators tension the inner conductor to counter thermal expansion and gravity, preventing arcing and short circuits in high-frequency power lines.
- Flexible Planar Transmission Line With Dual-Filter Mode Suppression
A dual-filter flexible planar line suppresses higher-order EM mode leakage beyond cutoff, reducing thermal noise in cryogenic qubit links.
- Glide-Symmetric Waveguide Filter Layout for Wide Stop-Bands
Offset elements on parallel plates create a glide-symmetric waveguide filter with wide stop-bands, low loss, and easier mm-wave manufacturing.
- MEMS Membrane-Bridge Phase Shifter for Fast Low-Loss Tuning
Electrostatic membrane-bridge motion varies capacitance for faster phase tuning and lower dielectric loss than ferrite or liquid crystal shifters.
- Metallized Dielectric Waveguide Filter Cavities for Unwanted Coupling Control
Angled metallized openings and spurious coupling windows suppress non-adjacent cavity coupling while reducing filter weight and fragility.
