Optimizing Compact Range Antenna Measurement with Sunyield’s SY-CATR Series

In the domain of compact range antenna measurement, Sunyield‘s SY-CATR series is a beacon of innovation. These systems integrate an integral curling surface, boasting an impressive RMS of less than 20um, thereby economizing on space compared to traditional saw-tooth reflectors. With a bias feed design, they facilitate both active and passive testing, creating an elliptical quiet zone within a specific longitudinal distance.

Flexible Customization for Diverse Testing Needs

Sunyield’s SY-CATR series is equipped with a multi-dimensional bearing turntable, allowing users to customize test tooling and electric auxiliary shafts based on specific requirements. The systems enable active/passive testing using a network analyzer or spectrum analyzer alongside the corresponding spread spectrum components, ensuring comprehensive and accurate assessments.

Seamless Integration and User-Friendly Deployments

For successful application, a fully shielded non-reflective microwave chamber with an adjustable feed fixture and a corresponding band ripple speaker feed is necessary.         Moreover, the inclusion of a movable base simplifies the process of placement and deployment, making the entire testing process user-friendly and efficient.


Sunyield’s SY-CATR series emerges as a pioneering force in the realm of compact range antenna measurement. With its innovative integral curling surface design, the system not only achieves exceptional precision with an RMS of less than 20um but also optimizes spatial efficiency, outshining conventional saw-tooth reflectors.

By combining cutting-edge technology with user-friendly features such as a movable base for easy placement and deployment, Sunyield’s SY-CATR series stands as a testament to precision, versatility, and convenience in compact range antenna measurement. This series marks a significant leap forward, promising to reshape and elevate the standards of antenna testing in diverse applications.
