Abstract
The traffic of information communication has continued to increase dramatically in our modern society. The use of millimeter (mm) waves has started to deal with the above trend in the new communication network technology called the fifth generation (5G) system. Here, the mm waves refer scientifically to radio waves of 1 to 10 mm in vacuum with frequencies from 30 to 300 GHz. Because the mm waves cover a wide frequency band, they can make it possible to build a high-speed large-capacity telecommunication system. However, the use of mm-waves in the 5G system has various concerns that must be addressed. One of the significant points is that most conventional printed wiring boards (PWBs) are hardly usable due to their high transmission losses. From this viewpoint, this short article briefly introduces technological trials for developing suitable materials for PWB substrates conducted by Fujikura, a major manufacturer of cables, insulating materials, and other transmission devices of power and telecommunication.
