Frequently Asked Questions

What is a waveguide slot array antenna?

A waveguide slot array antenna consists of a series of precisely cut slots in a waveguide wall that radiate electromagnetic energy. These antennas offer high efficiency, power handling, and directional gain, making them ideal for radar, satellite, and point-to-point communication systems.

What frequency bands do you support?

We manufacture antennas and components across multiple bands including X (8–12 GHz), Ku (12–18 GHz), K (18–27 GHz), Ka (26.5–40 GHz), and W (75–110 GHz), with custom designs available for other frequencies.

Do you offer custom design services?

Yes, we specialize in custom antenna and microwave component design. Our engineering team can develop solutions based on your specific requirements for frequency, gain, polarization, size, and environmental conditions.

What is vacuum brazing and why is it important?

Vacuum brazing is a high-precision joining process performed in a vacuum environment that ensures clean, strong, and hermetic seals. It's critical for microwave components where signal integrity, thermal performance, and reliability under extreme conditions are essential.

What applications are your antennas used in?

Our antennas are used in radar systems, satellite communications, 5G mmWave infrastructure, electronic warfare, scientific research, and industrial sensing applications requiring high-frequency precision.
