The impacts of rain on millimeter wave (mmW) terrestrial links, which are inev‐ itably affected by ground-objects-induced multipath propagation, are presented based on the signal time series data measured at 35 GHz. We analyze the coupled influence mecha‐ nism of rain-induced and ground-objects-induced multipath propagation on mmW terres‐ trial links. It can be deduced that the rain-induced impacts on millimeter wave terrestrial links cannot be neglected. The results given in this paper are significant for developing 5G millimeter wave terrestrial mobile communication links.

A novel phased array antenna consisting of 256 elements is presented and experi⁃ mentally verified for 5G millimeter-wave wireless communications. The antenna integrated with a wave control circuit can perform real-time beam scanning by reconfiguring the phase of an antenna unit. The unit, designed at 28 GHz using a simple patch structure with one PIN diode, can be electronically controlled to generate 1 bit phase quantization. A prototype of the antenna is fabricated and measured to demonstrate the feasibility of this approach. The measurement results indicate that the antenna achieves high gain and fast beam-steer⁃ ing, with the scan beams within ±60° range and the maximum gain up to 21.7 dBi. Further⁃ more, it is also tested for wireless video transmission. In ZTE Shanghai, the antenna was used for the 5G New Radio (NR) test. The error vector magnitude (EVM) is less than 3% and the adjacent channel leakage ratio (ACLR) less than −35 dBc, which can meet 5G sys⁃ tem requirements. Compared with the conventional phased array antenna, the proposed phased array has the advantages of low power consumption, low cost and conformal geome⁃ try. Due to these characteristics, the antenna is promising for wide applications in 5G milli⁃ meter-wave communication systems.
