WR-15 E-Plane Bend
The WR-15 E-Plane Bend is a precision-engineered waveguide component that redirects millimeter-wave signals by 90 degrees in the narrow wall (E-field) plane. It is specifically designed for the 50 - 75 GHz frequency range, serving as a critical building block in V-Band infrastructure.
E-plane bends curve along the shorter dimension of the rectangular waveguide cross-section, providing vertical signal routing while maintaining phase integrity. WR-15 spans the 50-75 GHz V-Band. Its 0.148" x 0.074" dimensions are the standard for 60 GHz commercial backhaul networks and inter-satellite links (ISL) in low earth orbit constellations.
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 the difference between an E-plane and H-plane bend?+
An E-plane bend curves the waveguide along its narrow wall (shorter dimension), shifting the electric field vertically. An H-plane bend curves along the broad wall (wider dimension), shifting the magnetic field horizontally.
How is WR-15 used in space applications?+
WR-15 is the standard for Inter-Satellite Links (ISL) in V-Band. Because there is no oxygen in space to absorb the 60 GHz signals, satellites can transmit massive amounts of data to each other using WR-15 feed networks and high-gain antennas without interference from Earth-based signals.
Are WR-15 components difficult to manufacture?+
Yes. At 75 GHz, the wavelength is only 4 millimeters. A manufacturing defect of just 0.1 mm inside a WR-15 component acts as a massive impedance mismatch. All RF Essentials WR-15 products undergo strict metrology and vector network analyzer testing.
