High-frequency PCB circuit board market outlook is optimistic

The high frequency PCB circuit board is a special circuit board with a high electromagnetic frequency. Generally speaking, the high frequency can be defined as a frequency above 1 GHz. Its physical properties, precision, and technical parameters are very high, and it is often used in automotive anti-collision systems, satellite systems, radio systems and other fields.

Wireless infrastructure needs to provide low enough insertion loss to effectively increase energy efficiency. With the advent of 4G services, RF products need to provide wider bandwidth and are backward compatible with 3G and 2G services. At the same time, the base station has become smaller and lighter, and has been installed on top of the tower, which has led to the development of circuit boards. In terms of handheld devices such as tablets, many manufacturers are looking for materials that can miniaturize antennas.

Handheld devices contain many antennas (Bluetooth, Wi-Fi, cellular, GPS, etc.) that are installed in a small space and do not interfere with each other. At the same time, each company's antenna design is different and requires flexibility. This puts high demands on the board material.
