What are the structural differences between an E-Plane Tee and an H-Plane Tee
May 20, 2025
In microwave engineering, waveguide components play a crucial role in signal transmission and power distribution. Among these components, E-Plane Tees and H-Plane Tees are fundamental elements that serve similar functions but differ significantly in their structural design and electromagnetic characteristics. The primary structural difference between an E-Plane Tee and an H-Plane Tee lies in the orientation of the auxiliary arm relative to the main waveguide. In an E-Plane Tee, the auxiliary arm is connected to the broad wall of the main waveguide, with its E-field aligned with the E-field of the main arm. Conversely, in an H-Plane Tee, the auxiliary arm is connected to the narrow wall of the main waveguide, with its H-field aligned with the H-field of the main arm. These structural differences result in distinct electromagnetic behaviors, making each type suitable for specific applications in high-frequency systems..webp)

The size and shape of an H-Plane Tee are critical determinants of its electromagnetic performance in microwave systems. These physical parameters directly influence the component's impedance matching, power distribution, frequency response, and overall signal integrity. When the dimensions of an H-Plane Tee are precisely engineered, the component delivers optimal power splitting with minimal reflection and insertion loss across the designated frequency band. The junction geometry, particularly where the auxiliary arm meets the main waveguide on its narrow wall, significantly impacts how electromagnetic waves propagate through the structure. Advanced Microwave Technologies' H-Plane Tees are meticulously designed with these considerations in mind, ensuring superior performance in applications ranging from satellite communications to defense systems where signal integrity is paramount.

How is the coupling coefficient of a broadwall directional coupler determined?
May 20, 2025
The coupling coefficient of a broadwall directional coupler is determined by the precise geometric configuration of the coupling holes that connect the primary and secondary waveguides, particularly their size, spacing, and arrangement pattern. In high-performance Broadwall Directional Couplers, a Tchebyscheff (Chebyshev) coupling hole distribution is often employed to achieve optimal electrical characteristics. This mathematical approach allows for precise control over coupling values, typically ranging from 10 dB to 40 dB, by carefully calculating the hole dimensions and their relative positions. The coupling coefficient directly affects how much power is sampled from the main transmission line, making it a critical parameter for applications requiring accurate power measurements, signal monitoring, and testing in microwave systems across telecommunications, aerospace, and defense industries.
