“…In order to reduce the required RF chains in high frequency measurement, the compact antenna test range (CATR) with the paraboloid reflector and a feed antenna at the focal has been investigated in ref. [22]. Reported studies [23,24] revealed that CATR could reduce the electromagnetic wave propagation distance and compensate for the free space path loss.…”

In millimetre wave (mmWave) frequency band, radio resource management (RRM) performance is characterised in plane wave conditions using radiated over‐the‐air test method, which is a challenging combination of protocol and radio frequency performance measurement. This article presents a novel design of multiple lens‐based compact antenna test ranges (CATRs) to simulate multiple angles of arrival from different base‐stations in RRM measurement. Only four lens‐based CATRs are proposed to create plane wave conditions at the device under test with six different angles of arrival and capable of accurately constructing the wireless propagation condition and minimising the diffraction and scattering between adjacent CATRs. The lens‐based CATR is the key element in the RRM measurement system, which is composed of a metasurface lens for phase alignment and a 2 × 2 feed array antenna for the emission of electromagnetic signals. The function and capability of the proposed lens‐based CATR is validated through simulation and measurement, that the worst‐case amplitude variation in the quiet zone region is lower than ±0.8 dB at 26 GHz, and phase variation is lower than ±7.5° in the designed quiet zone, which could be used in the fifth‐generation mmWave RRM measurement.

“…Although the sharp teeth has derived various shapes during this period [2], its low-frequency performance still cannot fully meet the actual use requirements. From 1984 to 1997 [3][4][5][6][7][8][9][10][11][12][13][14][15][16], Professor Burnside's team creatively put forward the concept and construction method of blended rolled edge and proved the advantages of this kind of edge processing method in improving the low-frequency performance of reflector. This method was widely used by researchers in the design of reflector used in CATR afterward, which is suitable for low-frequency testing [17][18][19][20].…”

It is of great practical value to study the blended rolled edge of reflector used in Compact Antenna Test Range (CATR). Taking a rectangular aperture reflector as the benchmark, a reflector with ideal blended rolled edge is obtained by means of parameter iterative optimization after accurately establishing the position relationship between the local and global coordinates where the blended rolled edge is located, precisely deriving the geometric equation of the main reflector zone and blended rolled edge zone in the local coordinate and optimizing continuity condition of curvature radius. On the basis, a blended rolled edge reflector with minimum operating frequency of 0.8 GHz and quiet zone size of 2 m is designed. The simulation results show that the performance of the reflector with blended rolled edge obtained by the proposed method is better than that obtained by the traditional construction method, and the designed reflector has excellent performance. The work in this paper provides a theoretical support for the optimal design and engineering application of the blended rolled edge reflector.

“…However, the beam combiner was made of dielectric material, which had poor ductility compared with the metal's material. It was difficult to make a curved edge [16, 17]. Therefore, in order to obtain good near‐field uniformity, an effective and easy to implement compensation method needed to be studied.…”
