High-speed, large-capacity wireless communication systems have become an indispensable infrastructure in all fields as a driving force for building a smart society.
The 60GHz band millimeter-wave (hereafter, “mmWave”) wireless system is license-free,low cost and facilitates building high-speed networks compared to licensed wireless communication systems such as 5G and local 5G systems.
The 60GHz system provides the best solution for customers who aim to achieve the following objectives:

・ Establishment of high-speed, wide-band private communication network
・ Smartification of various construction sites, workplaces, and commercial and industrial facilities
・ Transmisson of high-definition, low-delay images
・ V2X communication in public transportation (e.g. buses, trains) and various industrial vehicles
・ Building of wireless backhaul, wireless mesh networks

Fujikura develops a built-in mmWave wireless communication module for these 60GHz band wireless communication systems.

60 GHz mmWave Wireless Communications Module

Fujikura provides compact embedded 60 GHz mmWave wireless communications modules using a high gain phased array antenna. These are capable of achieving high-speed wireless communication in the 60 GHz frequency band. Their compact design combines a baseband wireless modem function and an antenna with an included RF front end function.
The mmWave bands are susceptible to large transmission losses due to wiring. Therefore, the wiring between the RF-IC and antenna must be as short as possible in order to maximize the features of the wireless communications module. High efficiency communications can be achieved through the selection of low loss materials for the circuit board and modularization of the RF-IC and antenna.

PRODUCT TECHNOLOGY

Point.1

RF-IC Design that Optimizes its Performance and Maximizes Output Power

This module employs a low loss multilayer LCP circuit board material and its layout design that optimizes RF-IC performance for even higher output. This allows the module to achieve world-class long-distance transmissions.

The figure below shows loss per 100 mm in a microstrip line(MSL).
The dominant source of loss in mmWave communications is the dielectric. So we selected a dielectric material with as little loss as possible.
LCP caught our attention because of its superiority as both a low loss and low-cost material.

Superiority of LCP material

Superiority of LCP material Superiority of LCP material
Transmission losses in mmWave communications can be large,
making it necessary to connect the RF-IC to the antenna with the
shortest possible wiring using low loss materials.
For this reason, the module adopts a structure that combines an RF-IC with an antenna comprised of a wiring pattern on the circuit board, in an integrated module.

Point.2

Antenna Design Maximizing High-frequency-band Performance

Fujikura's original antenna design and electromagnetic field analysis technology led us to develop a 16-element phased array antenna. It not only makes possible stable wide angle ±45 degree automatic beam forming, but at the same time achieves long-range transmission that fully covers the 57 to 71 GHz frequency band.

mmWave Realizes Gigabit-class High-speed Telecommunications mmWave Realizes Gigabit-class High-speed Telecommunications

In order to rapidly transmit and receive large amounts of data in a short time, it is essential to increase communication speeds. The use of broad frequency bands is one method for increasing communications speeds. At present, the Ultra-high Frequency (UHF) band, or so-called centimeter wave band, is used for communications. However, this frequency band is divided up for use by various applications. This makes it difficult to secure broad frequency bands.
For example, the 2.4 GHz and 5 GHz bands used by Wi-Fi are limited to bandwidths a mere 0.5 GHz wide or less (See 1 in the figure below). In contrast, few services have yet been allocated space in the mmWave band. This makes it possible to secure broad bandwidths. The 60 GHz band offers bandwidths of 9 GHz in Japan and 14 GHz in the US (See 2 in the figure below). These broad bandwidths offer communications speeds that are an order of magnitude faster than those of today. This will enable gigabit class high speed communications.
