Fifth generation (5 G) cellular network technology provides far faster and more reliable broadband access, with greater capacity and lower response times. New microwave (MW) materials are however, required to maximise the use of frequency ranges that have been made available for 5 G. 5 G requires components with lower power consumption (dielectric loss ~ 0.001), shorter delaytimes (latency, tpd ~1 ms as opposed to ~25 ms) and greater functionality than their 4 G counterparts [1–5]. Latency depends on the relative permittivity (r) of ceramics, according to:
