AI Technical Summary
Existing waveguide filter devices suffer from problems such as complex structure, low integration, insufficient stability, high in-band loss, and weak anti-interference ability, making it difficult to meet the signal transmission requirements under miniaturization and complex operating conditions.
The design employs an H-shaped air waveguide cavity and a T-shaped metal cover plate with a concave-convex fit, combined with a non-equidistant narrow-side U-shaped groove structure, and is fixed in one piece by fixing screws to form a compact filtering device that ensures the stability of signal transmission and anti-interference capability.
It achieves a return loss of less than -25dB in the passband and an out-of-band rejection capability of more than 50dB, improving signal transmission efficiency and stability, and is suitable for satellite communication and shipborne communication systems.
