IDG Contributor Network: The massive role of tiny antennas

The Shannon-Hartley theorem expresses “the maximum rate at which information can be transmitted over a communications channel of a specified bandwidth in the presence of noise.”

Translation: wireless data can only travel so fast. But if data rates are finite, how can we support the rollout of Gigabit LTE, and one billion new 5G connections by 2025?

Over the next few years, wireless connections will become ubiquitous – not only in our phones, tablets and PCs – but in our home, car and cities, thanks to an unglamorous and often-forgotten RF enabler: the antenna. Far from the laughably chunky antennas of early mobile phones, today’s nearly-invisible antenna systems make high-speed networking possible. They’re evolving as new wireless technologies emerge to satisfy our demand for content on the move.
