Wideband Antennas and Phased Arrays for Enhancing Cybersecurity in 5G Mobile Wireless

Fundamental issues on cyberspace and its security, in particular for 5G mobile wireless, are addressed from the concept of symmetric dual-space and dual-system. Formulated as a physical problem by narrowing "Information" to "Electronic Information," and "Communication" to "Telecommunication," with focus on "Observables," the current cyberspace is akin to a "biological" or "intelligent" system, and even vulnerable to Chaos. A practical solution to enhance both capacity and security/privacy is within reach by employing wideband diversity antenna systems, in particular wideband wide-scan mmWave phased arrays. Engineering, implementation, and business vision for this approach are discussed in the context of the ongoing pivotal and monumental global 5G mobile wireless thrust.
