  Thousands of satellites surround the Earth in their own orbital slots and even their own constellations, at distinct altitudes. They help communicate with distant places, track weather, and, with the Global Positioning System (GPS), find distant places here on Earth. Closest to Earth,…

Growing use of millimeter-wave (mmWave) frequencies for applications such as automotive radars, Fifth Generation (5G) wireless networks, and satellite communications (satcom) mandates careful selection of printed-circuit-board (PCB) materials specially formulated to transmit signals at frequencies to 70 GHz and higher. At the same time, digital…

Analog frequencies and digital data rates are increasing steadily in electronic circuits and systems, requiring careful choices of circuit materials for printed circuit boards (PCBs). Cellular communications technologies grew by means of RF and microwave signal frequencies, but Fifth Generation (5G) cellular wireless networks are…
