ACURAMW's Waveguide Probes for Nearfield Measurements

At ACURAMW, we are committed to providing the highest quality RF amplifiers, antennas, and microwave products. We recognize that precision and reliability are essential in achieving accurate RF testing results. That's why we're proud to introduce our Open Waveguide Probes, a versatile solution for near-field antenna measurement and calibration.

What is an open waveguide?

The open waveguide ended probe is designed for near-field measurements. They are linear polarization and are covering the frequency range from 0.32 to 110GHz (WR2300-WR10), 6 Typ. dBi Gain, with a low VSWR and by using standard WG band. All probes have an option of integration with absorber for better gain flatness and radiation pattern. The probe delivers exceptional performance for RF testing, making it ideal for antenna characterization and calibration. Its efficient and precise design ensures consistent and reliable measurements, which are essential for maintaining the accuracy and performance of antenna systems.

Key features of the waveguide probe series:

• Wideband Frequency: With low VSWR and 6 Min. dBi Gain, the 0.32 to 110GHz series of probe is optimized for a broad range of applications, providing high-performance results across various RF testing needs.
• Versatile Measurement Capabilities: The probe is suitable for both planar and cylindrical near-field antenna measurements, making it a flexible choice for different RF environments.
• Optional Absorber: To improve the stability and accuracy of the measurement, the probe can be equipped with an optional absorber with better gain flatness and radiation pattern.

Project Study: Practical Applications: How to Use Our WR90 Series Probes

The WR90 Series Open Ended Waveguide Probe has been successfully employed in real-world applications to achieve highly accurate and rapid RF testing. For instance, EM Path, a leader Institute in radio frequency testing, integrates the WR90 probe into their system to perform near-field measurements for X-band antennas. This enables them to efficiently gather 3D radiation pattern data and validate the performance of synthetic array antennas.

In these real-world tests, the WR90 probe was instrumental in beam-forming reconstruction, proving its capability in accurately representing antenna array patterns even when the probe was positioned just 20mm away from the antenna. These tests confirm the WR90's ability to achieve precise, real-time data in complex testing setups, making it ideal for use in antenna array systems and phased array testing.
