“…Furthermore, multiple components about 10 dB lower than the LOS component can be observed. Since no reflections ought to be coming from the wireless propagation in this environment, they must be due the front-ends, see also [8], [9], [10]. In fact, by inspecting the plots in the columns of Fig.…”

“…For a full system design it is also important to consider how the front-ends, i.e., the properties of their internal components, contribute to the frequency selectivity of the complete transmission chain. It has been observed, e.g., in [8], [9], [10], that front-ends operating at such high bandwidths generate significant frequency selectivity which needs to be taken into account, if not removed by some form of compensation during manufacturing.…”

Measurement results for millimeter wave LOS MIMO systems are presented with a focus on time variation and multipath propagation. Different system setups are used, including 2×2 and 3×3 MIMO, and involving different synchronization procedures and front-ends. Furthermore, different propagation scenarios are evaluated, covering a wide area of applications. The results show that the LOS component carries significantly more power than the NLOS components, and that frequency selectivity from front-ends should be taken into account when designing these high bandwidth systems. Frequency offsets and other phase variations due to transmit and receive oscillator differences are treated as part of the channel and thus, depending on the synchronization setup, the MIMO system exhibits different time variations, particularly in the case of independent local oscillators. It is also observed that these systems experience significant non-trivial long-term variations in terms of amplitude and phase.

“…At present, the 70/80GHz band (E-band) is rapidly gaining popularity, as it enables huge capacity and efficiency improvements for radios access and backhaul applications over 300 meters [1]. Several devices and product generations developed for the E-band is expected to mature for large-scale use during the 2020 to 2030 period.…”

In this paper a 140 GHz circularly polarized antenna is studied. The motivation of this work is to propose a suitable antenna configuration to reduce the subsequent manufacturing cost and complexity. The resultant antenna consists of a circular waveguide feed and a dielectric cover which is used to increase antenna directivity. Numerical study shows that the proposed antenna exhibits a 17% relative S11 bandwidth with a maximum gain of 16 dBi. The axial ratio is less than 3 dB ranging from 130 GHz to 155 GHz.
