The GBA_18-40d is a high-frequency Gaussian Beam Antenna (GBA) engineered for precision Non-Destructive Evaluation (NDE) within the 18 GHz to 40 GHz millimeter-wave (mmWave) spectrum. This system bridges the gap between traditional microwave frequencies and high-band mmWave testing, offering the same dual-polarization speed and depth advantages as the lower-frequency GBA models.

Core Engineering Specs

• Model: GBA_18-40d
• Frequency Range: 18 GHz – 40 GHz
• Integrated Dual Polarization: Built-in dual polarization allows for high-speed, multi-axis data acquisition without the need for manual antenna rotation.
• Enhanced Inspection Field: Maintains a highly planar wave within 3 inches from the antenna tip, providing a deeper inspection zone for thick mmWave-transparent materials.
• Dynamic Range: Greater than 70 dB, supported by mechanical and software-driven noise floor optimization.
• Technology: Gaussian Beam focus optimized for high-frequency stability across K and Ka bands.
• Compatibility: Industry-standard VNA Universal Compatibility.

Primary Utility

The GBA_18-40d is the premier tool for characterizing materials used in 5G infrastructure, satellite communications, and high-speed aerospace electronics. By delivering a 3-inch planar zone at these higher frequencies, it provides superior accuracy when measuring the dielectric properties of thick panels and high-performance radome structures that are sensitive to over-illumination.
