WR-03 E-Plane Bend
The WR-03 E-Plane Bend is a precision-engineered 90-degree waveguide bend that redirects millimeter-wave signals in the narrow wall (E-field) plane within the 220 GHz - 330 GHz frequency range, commonly associated with the J-Band.
E-plane bends curve along the shorter dimension of the rectangular waveguide cross-section, providing vertical signal routing. The optimized bend radius maintains consistent VSWR and minimal insertion loss across the full J-Band operating bandwidth. Constructed from OFHC copper with gold plating for reliable long-term performance.
Key Features
E-Plane Geometry
Bend follows the narrow wall (shorter dimension) of the waveguide, routing signals vertically while maintaining the broad-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.

Frequently Asked Questions
What is a WR-03 E-plane bend?+
A WR-03 E-plane bend is a precision waveguide component that redirects millimeter-wave signals by 90 degrees in the narrow wall (E-field) plane within the J-Band frequency range of 220 GHz - 330 GHz.
What is the difference between E-plane and H-plane bends?+
An E-plane bend curves the waveguide along its narrow wall (shorter dimension), used for vertical routing. An H-plane bend curves along the broad wall (wider dimension), used for horizontal routing.
Can custom bend angles be manufactured?+
Yes. While 90-degree bends are standard, RF Essentials can manufacture custom E-plane bend angles and radii for WR-03 waveguides. Contact our engineering team with your requirements.
