What is High Frequency PCB? Just as its name implies, high frequency is that the frequency is relatively high, generally refers to the frequency of >=300 MHz (i.e. wave length <=1m), that is, the usual radio frequency band. The electromagnetic wave of frequency >=1GHz is called microwave. Typical frequencies for wireless applications: * Current mobile: 0.9GHz - 2GHz * 3G systems: 2.5GHz *...

1. An uWB monopole antenna based on four-layer printed circuit board (PCB) is designed based on the method of resonance of multiple radiating patches in different frequency bands. The antenna is fed by microstrip and has two patches of different sizes on two different planes of the dielectric substrate. In order to realize the miniaturization of the antenna, a multilayer uwb monopole antenna with ...

Generally speaking, high frequency can be defined as the pre-rate above 1GHz. The most commonly used high-frequency circuit board substrates are fluorine-based dielectric substrates. For example, polytetrafluoroethylene (PTFE) is usually called Teflon, which is usually used above 5GHz. , In addition, FR-4 or PPO substrate is also used, which can be used for products between 1GHz-10GHz. The physica...
