Over-the-Air Radiated Testing of Millimeter-Wave Beam-Steerable Devices in a Cost-Effective Measurement Setup

Abstract: With the severe spectrum congestion of sub-6GHz cellular systems, large-scale antenna systems in the millimeter-wave (mmWave) bands can potentially meet the high data rate envisioned for fifth generation (5G) communications. Performance evaluation of antenna systems is an essential step in the product design and development stage. However, conventional cable conducted test methods are not applicable for mmWave devices. There is a strong need for over-the-air (OTA) radiated methods, where mmWave device performa… Show more

“…The DUTs targeted in the paper are non-adaptive high-order LTE terminals and LTE-V systems, where the number of receive antennas is typically limited in the spatial transmission mode. It is noted that for end-to-end performance testing of large-scale adaptive antenna systems, the simplesectored MPAC (SS-MPAC) setup is actively discussed in the literature [30]- [32].…”

“…Secondly, for the sub-6 GHz OTA testing system, the spatial correlation is used to estimate the reconstruction of the channel directly. However, the mmWave massive MIMO systems are more directive and the channel is highly sparse and specular; therefore, spatial correlation function might be less relevant to determine OTA system performance [6]. Finally, the mmWave massive MIMO antennas have the beamforming capability, which should be studied when testing the performance of the DUT.…”

“…Finally, the mmWave massive MIMO antennas have the beamforming capability, which should be studied when testing the performance of the DUT. erefore, the selected evaluation metrics need to emphasize the performance of the beam, e.g., beam acquisition, tracking, refinement, and recovery [6]. Based on the above description, angular spectrum is selected as the test metric in the sequel.…”
