The anatomy of 5G antenna hardware

An article written by Majeed Ahmad, contributing writer for Electronic Product – Here is how the active antenna system, antenna tuning, and massive MIMO antenna technologies are being implemented in 5G radio designs.

The RF front end (RFFE) is becoming increasingly complex in 5G designs due to the growing number of frequency bands. Subsequently, more antennas are required to deliver higher data rates while they implement carrier aggregation (CA) and multiple-input, multiple-output (MIMO) technologies and millimeter-wave (mmWave) frequency bands.

Not surprisingly, therefore, we are witnessing a higher level of component integration in 5G antenna and RF front-end modules. These modules are ramping up integration to drive additional RF content in multi-band 5G communications. 

This article will show how the 5G wireless revolution is transforming antenna hardware and its interface to RF front-end designs. It will explain key technology drivers like antenna tuning and provide an insider’s view on smart antenna systems on the cusp of commercial realization. Let’s begin with active antenna systems (AAS) used in 5G base stations.

Active antenna systems
The technological complexity of 5G antennas is very high for cellular and mmWave spectrum bands. That’s mainly because 5G designs utilize multiple antenna modules in an array, and signals are concentrated in multiple directions. At the same time, however, it’s imperative that designers improve signal efficiency while also reducing antenna size and power consumption… Full article
