Evolution of Millimeter-Wave Multi-Antenna Systems in the IoT Era

The enormous growth of wireless data traffic in recent years has made the millimeter-wave (mm-wave) technology as a good fit for high-speed communication systems. Extensive works are continuing from the device to system, to the radio architecture, to the network to support the communication in mm-wave frequency ranges. To support this extensive high data rate, beam forming is found to be the key-enabling technology. Hence, an array antenna design is an extremely important issue. The beam-forming arrays are chosen to achieve the desired link capacity considering the high path loss and atmospheric loss at mm-wave frequencies and also to increase the coverage of the mm-wave communication system. There are diverse design challenges of the array due to the small size, use of large numbers of antennas in close vicinity, integration with radio-frequency (RF) front ends, hardware constraints, and so on. This paper focuses on the evolution and development of mm-wave array antenna and its implementation for wireless communication and numerous other related areas. The scope of the discussion is extended on the reported works in every sphere of mm-wave antenna array design, including the selection of antenna elements, array configurations, feed mechanism, integration with front-end circuitry to understand the effects on system performance, and the underlying reason of it. The new design aspects and research directions are unfolded as a result of this discussion.INDEX TERMS Mm-wave communication, antenna array design, array configuration, feed mechanism, RF circuit.

“…The circuit model presents a maximum average error of 5.1% for the return loss (i.e., jS 11 j) when compared with experimental data. Furthermore, with the purpose of measuring the impact of these inter-metallic elements in the performance of RF applications [16,17,18,19,20,21], the via stack circuit model is applied here for representing a RTWO. The importance of this particular application example relies on the fact that this type of oscillators allow fulfilling the design requirements for high frequencies applications (i.e.…”

This work proposes an experiment-based characterization and modeling approach for interconnection channels including via stacks as vertical transitions. A daisy chain structure implemented in a 0.18 µm RFCMOS process is used for developing and verifying the validity of the proposal. The usefulness of the models is shown by assessing the impact of the vias in a practical resonant rotary traveling wave oscillator (RTWO). The oscillation frequency of the RTWO is reduced 13.7% when the via stack models are included.
