Learn antenna is a dry cargo antenna technology column focusing on antenna simulation and debugging, supplemented by theoretical principles, including introduction to antenna, principle introduction of various antennas, simulation software modeling, desig

The traditional car is an isolated individual. As the name suggests, Internet of vehicle (IOV) is to let the car connect to the Internet. This is a subdivided application of the Internet of things (IOT: Internet of things) in the automotive

Since five years ago, the network has gradually transitioned from 4G network to 5g network. One of the most obvious changes is the increase of network frequency. In the 4G era, we mainly use frequencies of 2.6GHz and below. In the 5g era, the frequency ba

The filter is the core RF device of the base station. The filter filters the electromagnetic wave signal and only allows the required signal to pass through. The main purpose is to solve the interference problem between different frequency bands and diffe
