High frequency PCB circuit board is a special type of circuit board with high electromagnetic frequency. Generally speaking, high frequency can be defined as a frequency above 1GHz. Its various physical properties, accuracy, and technical parameters require very high requirements, and are commonly used in fields such as automotive collision prevention systems, satellite systems, and radio systems.

　　Wireless infrastructure needs to provide sufficiently low insertion loss in order to effectively improve energy utilization efficiency. With the arrival of 4G services, RF products need to provide wider bandwidth and be compatible with 3G and 2G services. PCB sample manufacturers believe that at the same time, base stations are becoming smaller and lighter, and are installed on top of towers, which is also promoting the development of miniaturization of circuit boards. Many manufacturers are seeking materials that can miniaturize antennas in handheld devices such as tablets.

　　Optimistic market outlook for high-frequency PCB circuit boards

　　Handheld devices contain many antennas (Bluetooth, Wi Fi, cellular communication, GPS, etc.), which are installed in a small space and cannot interfere with each other. Meanwhile, each company's antenna design is different and requires flexibility. PCB board sample manufacturers feel that this places high demands on circuit board materials.
