Waveguides TRIZ Cases
- Vertical Microstrip-to-Waveguide Transition With Air-Gap Tolerance
A tapered vertical transition links PCB microstrip to waveguide with broad bandwidth, low reflection, and tolerance to assembly air gaps.
- Plug-In Waveguide Filter Structure for Low-Loss Antenna Arrays
Air-filled waveguide tubes use dielectric-held plug-in filter elements to cut insertion loss and simplify antenna array integration.
- Voltage-Controlled RF Waveguide Switching for Multi-Band Signal Routing
Voltage-reactive waveguide elements enable tunable RF splitting and switching across multiple bands, supporting mm-wave and THz signal routing.
- Dielectric-Loaded Waveguide Structure for Low-Loss Wide Bandwidth
Dielectric bars inside a hollow waveguide cavity widen bandwidth while keeping microwave losses low for millimeter-wave transmission.
- Tapered Dielectric Waveguide Connector for Low Return Loss
A tapered dielectric waveguide end smooths impedance transition to hollow metallic tubes, cutting transmission and return losses.
- Waveguide Interposer Interface for Antenna Alignment and Isolation
A waveguide interposer creates separate reference planes between the IC antenna and dielectric waveguide to improve alignment, isolation, and impedance matching.
- Compact RF Polarizer Group With Tunable High-Power Waveguide Coupling
Adjustable circular-waveguide shorts enable compact RF polarizers to handle high power while tuning isolation, transmission, and broadband response.
- Vehicle Radar Antenna Links Using Terahertz Dielectric Waveguides
Terahertz signals in dielectric waveguides replace complex shielded radar wiring, preserving coherence and high angular resolution in vehicles.
- Asymmetric Wilkinson Power Splitter Layout With Open Stub Compensation
Open stubs compensate unequal line lengths in a multistage Wilkinson splitter-combiner, cutting footprint and wiring loss.
- Crossover Transmission-Line Splitter for Wideband Port Isolation
Crossed return paths and isolation resistors help a quarter-wave splitter maintain port matching and isolation across a wide frequency range.
- Spliced Suspended Strip Line for Long RF Path Assembly
Segmenting a long suspended strip line with connectors eases fabrication and installation while preserving impedance matching and reducing signal loss.
- Ridge Waveguide Interface Using Capacitive Coupling in Tight Spaces
Capacitive coupling between overlapping ridge and standard waveguides saves connector space while preserving high-frequency signal quality.
- Stacked Microstrip Waveguide Power Combiner for Low-Loss Size Reduction
Stacked substrates with overlapping microstrip lines form a compact waveguide power combiner that cuts size and transmission loss.
- Self-Aligning Waveguide Connector With Ball Detent RF Coupling
Ball detent retention and radial alignment features enable repeatable separable waveguide joints with low signal loss and reduced RF reflection.
