In this paper, a novel compact antenna test range based on transmitarray (TA), transmitarray compact antenna test range (TACATR), is proposed. A non-negligible parameter, central cell reference phase (CRP), is defined to harmonize the disturbance field. The CRP not only determines the physical structure of TA, but also can adjust the phase of the desired plane wave field of the quiet zone (QZ). Several strategies are proposed to enhance the performance of QZ of TACATR. The strategies include selecting CRP and the layout of TACATR. To validate the feasibility of TACATR, a 169.6 mm � 169.6 mm TA working at 28 GHz is designed, simulated and fabricated. The measured amplitude peak to peak value (P2P) of the middle QZ plane field is 1.5 dB and the phase P2P is 9.4°.

Nowadays, electronic products are being used extensively in many fields and applications. The dense population of electronic devices in human life has become a challenge for microwave engineers to ensure that their products can meet the Electromagnetic Compatibility (EMC) standards. Complex electronic products with smaller sizes and denser components will be a challenge for compliance with EMC standards. In addition, the occurrence of non-stationary emission at certain operating modes becomes a challenge for analysis. Error in analyzing EM emissions will make the products unable to meet the requirements of EMC standards; hence, they will be prohibited to be marketed. Currently, there are two methods of emission analysis, i.e. by measurement and modeling or computation. There are some problems, however, in the analysis of EM emissions regarding the area of test, complexity, DUT positioning error, installation cost, and time consumption. In this paper, the analysis techniques for EM emissions including Open Area Test Site (OATS), Anechoic chamber, Transverse Electromagnetics TEM Cell, Compact Antenna Test Range (CATR) and near field scanning are reviewed comprehensively. This survey covered EMC standards, principles of EM emission measurement techniques, advantages and disadvantages of EM emission measurement techniques, studies and applications of each technique, recommendations for which technique to be used, and challenges for future research in EM emission measurement. The final section of this paper discusses the challenges for near-field measurements related to the non-stationary emissions phenomenon. This papers also presents the challenges of how to detect and characterize them.

“…In ref. [26], a very small focal‐to‐diameter (F/D) ratio transmitarray for generating a high‐quality QZ at 2.6 GHz is proposed, but few works have been done in mmWave frequency band. In comparison with reflector‐based CATR, lens‐based CATR enables to generate a large and high quality QZ in a wide range without performance degradation.…”

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.
