The GBA_2-18d is an ultra-wideband Gaussian Beam Antenna (GBA) optimized for high-speed Non-Destructive Evaluation (NDE) across the 2 GHz to 18 GHz spectrum. This model is a cornerstone of the GBA series, providing the broadest frequency coverage in a single unit for comprehensive material analysis.

Core Engineering Specs

• Model: GBA_2-18d
• Frequency Range: 2 GHz – 18 GHz
• Integrated Dual Polarization: Optimized for simultaneous dual-pol data acquisition, significantly increasing inspection efficiency and reducing manual handling.
• Enhanced Inspection Field: Delivers a highly planar wave within 3 inches from the antenna tip, making it the ideal choice for inspecting thick or multilayered structural composites.
• Dynamic Range: Greater than 70 dB, utilizing MWI’s signature mechanical and software noise reduction enhancements.
• Technology: Precision Gaussian Beam optics designed for stable performance across a massive 16 GHz bandwidth.
• Compatibility: Universal VNA compatibility for high-resolution S-parameter measurement.

Primary Utility

The GBA_2-18d is designed for high-stakes aerospace and defense applications that require a “one-stop” solution for broad-spectrum NDE. The combination of dual polarization and a 3-inch planar inspection zone allows for the rapid characterization of thick radomes, RAM (Radar Absorbing Material), and complex airframe structures without switching antennas.
