The first is from passive antennas to active antenna systems.

This means that the antenna may be intelligent, miniaturized (co-designed), and customized.

As the future of the network will become more and more detailed, we need to customize the design according to the surrounding scenes, for example, the station in the urban area will be more elaborate, rather than simple coverage. 5G communication will use high-frequency bands, obstacles will have a great impact on communication, and customized antennas can provide better network quality.

The second trend is the systematic and complex antenna design.

For example, beam arrays (implementing space division multiplexing), multiple beams, and multiple/high-frequency bands. These all put high demands on the antenna, it will involve the whole system and the problem of mutual compatibility. In this case, the antenna technology has surpassed the concept of components and gradually entered the design of the system.


The evolution of antenna technology: from the single array of antennas to multiple arrays to multiple units, from passive to active systems, from simple MIMO to massive MIMO systems, from simply fixed beams to multiple beams.

Design level trend


For base stations, a major principle of antenna design is miniaturization.

Antennas of different systems are designed together and are small enough to reduce cost and save space. Therefore, the antenna is required to be multi-band, wide-band, multi-beam, MIMO/Massive MIMO, and MIMO to antenna isolation. Massive MIMO has some special requirements for the hybrid coupling of antennas.

In addition, the antenna also needs to be tunable.

The first generation of antennas was mechanically used to achieve tilt angles, and the third generation achieved remote ESCs. 5G is very attractive if it can be self-tuned.


For mobile terminals, the requirements for the antenna are also miniaturized, multi-band, wide frequency band, and tunable. Although these features are now available, the 5G requirements will be more demanding.
