Spherical near-field test is to use a set of characteristics of the fixed known probe in the DUT radiation near-field region of the sphere to scan, get the antenna in the sphere of the radiation near-field amplitude and phase distribution with the position change of the relationship between the near-field and then by the near and far-field spherical Fourier algorithm converted to far-field directional diagrams, this means of testing completely breaks through the limitations of the conditions of the far-field, and also circumvented the expensive cost, is the popularity of the relatively high This test method completely breaks through the limitation of far-field conditions, and also avoids the expensive cost, which is the popularity of the current higher test method, is a recognised and efficient antenna test solution.

The spherical near-field system is mainly composed of a multi-probe array, a turntable system, an RF link system, and an antenna darkroom.

Currently, Rflight is able to build and design -
Multi-probe spherical near-field test system: test frequency 400MHz-18GHz, support 16, 24, 32, 64, 128, 180, 192 probes;
Planar near-field test system: test frequency 100MHz-60GHz;
Tight field test system: test frequency 400MHz-500GHz, static area range 0.3-10 metres;
RF reverberation room test system: test frequency 1GHz-60GHz.It meets the testing of various indexes of antenna (base station), automotive electronics, millimetre wave antenna, radar and other antenna feeder systems such as 4G, 5G and 6G antennas.

OTA system

At present, Rflight provides complete 5G OTA test solutions to meet the testing of 4G, 5G, 6G antennas (base stations), automotive electronics, millimetre wave antennas and other antenna system indicators, and has successfully constructed and delivered the first set of 5G 192-probe spherical near-field system for the leading domestic communication enterprises, and the world's first set of ultra-large 5G 110G 3-metre static tight-field test system for communication, etc. Rflight has also provided mature OTA solutions for the domestic mainstream terminal manufacturers, antenna manufacturers, certification laboratories, etc., and has received good comments.
Meanwhile, Rflight has also provided mature OTA solutions for domestic mainstream terminal manufacturers, antenna manufacturers, certification laboratories, etc., and received unanimous praise.
