The second solution is to design the antenna in a package integrated antenna (PIA).

Because the biggest problem with the antenna on the chip is that the loss is too large, and the size of the chip itself is small, the design of the antenna will increase the cost, so it is almost impossible to obtain a large-scale application in engineering. If the antenna is designed with a package (larger than the chip) as a carrier, not only can a single antenna be designed, but also an antenna array can be designed, which avoids the limitation in size, loss, and cost of the antenna directly on the silicon.

In fact, the antenna can be designed not only inside the package but also at the top, bottom and around the package.

Another point to be aware of is whether the PCB can be used as an antenna. The answer is yes.

The key bottleneck is not the material itself, but the design and processing problems that the material brings. However, the PCB is only suitable for the frequency band below 60 GHz, and LTCC is recommended after 60 GHz, but after 200 GHz, the LTCC also has a bottleneck.

 

To sum up

In the future, the antenna must be designed together with the system instead of being designed separately. It can even be said that the antenna will become a bottleneck of 5G. If the bottleneck is not broken, the signal processing on the system cannot be realized, so the antenna has become a 5G mobile communication system. Key technology. An antenna is not just a radiator. It has filtering characteristics, amplification, and suppression of interference signals. It does not require energy to achieve gain, so the antenna is more than just a device.
