FAQ
- What is a 64-element subarray in phased array antenna systems?
- A subarray is a grouped antenna element structure that simplifies system design by combining multiple elements into a modular unit, reducing complexity while maintaining beamforming capability.
- What is the benefit of shared-aperture design?
- Shared-aperture architecture allows transmit and receive functions to use the same physical antenna surface, significantly reducing size, weight, and system cost.
- Why is air-dielectric thin-film technology used here?
- Air-dielectric structures reduce RF signal loss and improve antenna efficiency compared to traditional solid dielectric materials, making it suitable for low-power SATCOM terminals.
- What applications is this subarray module suitable for?
- It is mainly used in scalable Ku-band phased array terminals, mobile satellite communication systems, and compact SATCOM terminals requiring modular antenna architectures.
- Does this module support integration with larger phased array systems?
- Yes. The 64-element subarray is designed as a building block that can be integrated into larger phased array antenna systems for scalable performance expansion.
