What kind of antennas are expected to be used more frequently in the development of advanced wireless technologies like 5G?

The increasing use of more smaller antennas in the development of advanced wireless technologies like 5G is primarily due to the need for improved performance and coverage in denser urban environments. Smaller antennas can be deployed in greater numbers, allowing for more effective handling of the higher data rates and increased capacity that 5G technology promises. This is crucial because the higher frequencies utilized by 5G can lead to reduced range and penetration through obstacles; thus, having many small antennas can help maintain signal strength by ensuring closer proximity to the end-user devices.

Additionally, small antennas support the deployment of dense networks, such as small cell architectures, which improve signal quality and reduce latency. This trend is in line with the overall industry movement towards deploying many smaller, more efficient antennas rather than relying on fewer larger ones, which may not be as adaptable to new environments or as capable of providing the necessary coverage in highly populated areas.
