The 110G high-frequency compact field system has passed customer acceptance

A set of 110G high-frequency compact field testing system built by Sunyield in September 2022 has passed customer acceptance. This system is currently one of the most frequently tested systems in China, with a design frequency of 18 ` 110GHz. At present, the system has been accepted and put into use.

Advantages of Tight Field Testing

Tight field testing is a method of using collimating devices to achieve plane wave testing conditions. Tight field technology refers to a measurement technique in which people use the reflection principle of electromagnetic waves in the measurement of antenna and target characteristics, and use reflection surface technology to obtain approximately uniform plane wave irradiation that meets the measurement requirements, in order to shorten the measurement distance.


Taking the 24GHz frequency band test as an example, if the size of the tested object is a 90cm array fixed amplitude phase radar, its far-field testing conditions need to reach nearly 130 meters, and 90GHz needs to reach about 480 meters. Therefore, generally, millimeter wave testing will choose compact field or near-field testing.


The compact field is a highly complex system engineering that involves multiple disciplines such as electromagnetic scattering theory, high-precision antenna design and manufacturing, measurement and assembly technology. Sunyield has been researching in the field of compact field testing for many years, and has rich experience in high-precision edge rolling reflector manufacturing, high-precision feed and positioning device manufacturing and installation, high-precision measurement and installation technology, and other aspects.

  • SY-CATR

    The SY-CATR series are a variety of compact range measurement systems released by Sunvey Technologies for application in the millimeter wave detection field. As the millimeter wave radar features wide frequency band and small size, the SYCR series of different sizes can set up excellent experimental environment for millimeter-wave radar testing and design. Mainly used for testing automotive radars and their components, millimeter wave military/police radar products, and civilian millimeter wave antennas (millimeter wave reflector antennas, 5G millimeter wave communication antennas)

  • SY-68 SISO&MIMO

    The SY-68 probe spherical near-field antenna measurement system supports measurements in the 400MHz-8.5GHz, 600MHz-12GHz,400MHz~18GHz frequency bands, and supports secondary development of standard interfaces. Compared to the standard SY-24 system, it supports a larger measurement range (with a diameter of up to 2.5m), higher sampling density, active and passive measurements, and can also measure small base station antennas. It is suitable for testing and research institutions such as terminal manufacturers, third-party laboratories, and base station research and development.

  • SCR-5000

    Sunyield SCR-5000 cylindrical measurement system, the first linear array multi-probe cylindrical measurement system in the industry, innovatively integrates spherical multi-probe technology into the cylinder surface to ensure test accuracy while significantly saving space and cost. The system adopts multi-probe calibration technology and electronic solid-state switch to quickly collect data to measure the 3D pattern of the antenna, and at the same time expand S-parameter information such as standing wave and isolation according to user requirements. According to the characteristics of cylindrical system, this system is particularly suitable for the measurement of base station antennas with narrow vertical beam.
    In general, the measurement of 3D pattern can be achieved with the cost of a chamber for PIM or standing wave, and the system is especially suitable for prototype diagnostic testing in R&D and batch sampling in production.
