WR-10 H-Plane Bend
The WR-10 H-Plane Bend is a precision-engineered waveguide component that redirects millimeter-wave signals by 90 degrees in the broad wall (H-field) plane. It is specifically designed for the 75 - 110 GHz frequency range, serving as a critical building block in W-Band infrastructure.
H-plane bends curve along the wider dimension of the rectangular waveguide cross-section, providing horizontal signal routing without inducing higher-order modes. WR-10 encompasses the 75-110 GHz W-Band. It is heavily utilized for 77 GHz automotive radar systems (ADAS), requiring internal waveguide dimensions of precisely 0.100" x 0.050".
Key Features
H-Plane Geometry
Bend follows the broad wall (wider dimension) of the waveguide, routing signals horizontally while maintaining the narrow-wall dimension.
Low Insertion Loss
Optimized bend radius and CNC-machined interior walls ensure minimal signal degradation through the 90-degree turn.
Precision CNC Machined
Each bend is machined from a solid billet of OFHC copper, maintaining tight dimensional tolerances throughout the bend radius.
Gold-Plated Construction
Gold plating provides excellent conductivity, corrosion resistance, and consistent electrical performance over the component's service life.
W-Band Use Cases
Automotive Radar
77 GHz ADAS sensors
Passive Imaging
Security millimeter-wave
Defense Seeker
Missile terminal guidance

Frequently Asked Questions
Why use an H-plane bend over an E-plane bend?+
H-plane bends are used when the signal needs to be routed horizontally across an optical table or chassis without twisting the polarization of the wave. The wider bend radius typically handles higher peak power than an E-plane bend.
Why is WR-10 the standard for automotive radar?+
The global standard for Advanced Driver Assistance Systems (ADAS) radar is 77 GHz to 81 GHz. WR-10 components (W-Band) are required for all test, measurement, and calibration systems used in the development and manufacturing of these automotive radar chips.
Can WR-10 handle high power?+
Because the aperture is only 0.100" x 0.050", the electric field density inside WR-10 is extreme even at moderate power levels. While it handles less total power than WR-28, a dry, nitrogen-purged WR-10 component can still safely pass over 100 Watts of CW power before experiencing dielectric breakdown.
