5G communication technology is used in very demandingapplications, such as high-performance mobile devices, Internet of Things (IoT)applications, and wearable devices. Therefore, unlike the previous technologies,5G technology requires massive bandwidth, mainly withinthree key frequency ranges, Sub-1 GHz, 1-6 GHz, and above 6 GHz. However, thesechallenges require more accurate and wide-band characterization of the circuitsdesigned for 5G systems. To be specific, the losses, which can be neglected atlower frequencies, may substantially affect the performance of these circuitsin the high frequency bands. This requires a comprehensive understanding andproper characterization of the loss mechanism within all frequency band of 5G. Thispaper investigates the viability of using the most common and easily accessiblematerial FR-4 in circuits designed for 5G applications, and thus focuses on theproper modeling of the microstrip lines built around FR-4. For this purpose, wehave used the fractional-order model of the lossy dielectric material, andended up with a more accurate and simple model which fits well within a widefrequency range, from 1GHz to 16GHz.
