8 to 18GHz Point Focus Lens Antenna

Point Focus Lens Antenna 8-18GHz

This product is a Point Focus Lens Antenna designed for material testing and other applications requiring concentrated electromagnetic energy. The antenna operates from 8GHz to 18GHz and is built from aluminum for light weight and good durability. As a Point Focus Lens Antenna, it concentrates the radiated energy into a small focal spot. The focal length is fixed at 500mm, and the focal spot size is controlled within a small diameter. This design allows users to focus microwave energy onto a specific point on a material sample. The antenna is typically used in pairs one as a transmitter and one as a receiver for transmission and reflection measurements. Compared to full material test systems, this point focus lens antenna offers a lower cost entry point for users who need basic focused beam testing capabilities.

This lens antenna operates across the frequency range from 8GHz to 18GHz, covering the X band and part of the Ku band. The Voltage Standing Wave Ratio (VSWR) is rated at 2.5, which is typical for this type of focused lens design. The antenna is made from aluminum, which keeps it lightweight while providing good structural strength. The focusing capability allows users to measure localized material properties without needing large uniform sample areas. This is especially useful when testing small or inhomogeneous samples. The antenna is often used in free space material characterization setups where a focused beam helps improve measurement accuracy by reducing edge diffraction effects. Users need to manually adjust the lens focus point during testing to achieve optimal results for different sample positions.

One clear strength of this Point Focus Lens Antenna is its cost effectiveness. For labs or users who cannot justify the expense of a full automated test system, these antennas provide a practical alternative. They are well suited for characterizing dielectric constant, permeability, transmission rate, reflection rate, and absorption rate of materials under microwave conditions. The main application areas include scientific research, industrial testing, military applications, and communication systems. Core service areas include lens antenna development, next generation communication, radar stealth technology, aerospace, and advanced material research. The point focus design helps address testing needs involving wide frequency coverage, high temperature conditions, large sample handling, high precision requirements, and non destructive testing. For engineers and researchers working on new materials, these antennas offer a reliable way to gather measurement data.

In practical use, this Point Focus Lens Antenna handles a variety of material testing tasks well when used in pairs. One antenna transmits the focused beam toward the sample, and the other receives the signal that passes through or reflects off the sample. The 500mm focal length provides a reasonable working distance for most sample sizes. The small focal spot allows users to scan across a larger sample to map property variations. While manual focus adjustment is required, this also gives users direct control over the setup. The aluminum construction ensures the antenna remains stable during measurements. It stands as a solid example of how a well designed Point Focus Lens Antenna can provide focused beam testing capabilities at a lower cost point, making material characterization accessible to a wider range of users.
