The antennas of the 1980s were mainly dominated by single-polarized antennas, and the concept of arrays has begun to be introduced. Although omnidirectional antennas also have arrays, they are only vertical arrays, and single-polarized antennas have planar and directional antennas. In terms of form, the current antenna is very similar to the second generation antenna.

In 1997, dual-polarized antennas (±45° cross-multi-polarized antennas) began to enter the historical arena. At this time, the performance of the antenna has been greatly improved compared with the previous generation. Whether it is 3G or 4G, the main trend is a dual-polarized antenna.

In the 2.5G and 3G era, many multi-band antennas appeared. Because the system at this time is very complicated, such as GSM, CDMA, etc. need to coexist, the multi-band antenna is an inevitable trend. In order to reduce costs and space, multi-band has become the mainstream at this stage.

By 2013, we introduced the MIMO (Multiple-Input Multiple-Output) antenna system for the first time. Originally a 4x4 MIMO antenna.

MIMO technology has increased communication capacity, and the antenna system has entered a new era, from the original single antenna to the array antenna and multiple antennas.

However, now we need to look into the distance, the deployment of 5G has started, what role will antenna technology play in 5G, and what effect will 5G have on antenna design? This is a problem we need to explore.

In the past, the design of the antenna was usually very passive: after the system design was completed, the indicator was added to customize the antenna. However, the current concept of 5G is still unclear. R&D personnel who do antenna design need to be prepared in advance to provide solutions for 5G communication systems, and even influence the customization and development of 5G standards through new antenna solutions or technologies.


From the experience of cooperation and exchange between mobile communication companies in the past few years, there are two major trends in base station antennas in the future.
