What is PCB antenna?

 The PCB antenna refers to the part on the PCB for wireless reception and transmission, which belongs to the Microwave radio frequency board of the High frequency board. The antenna is a kind of energy converter. When transmitting, it converts the high-frequency current of the transmitter into space electromagnetic waves; when receiving, it converts the electromagnetic waves intercepted from space into high-frequency currents and sends them to the receiver. For the design of a Microwave radio frequency board for low-power, short-distance wireless transceiver equipment used in radio frequency identification systems, antenna design is an important part of it. A good antenna system can make the communication distance reach the best condition. There are many types of antennas, and different applications require different antennas. In a low-power, short-distance RFID system, a reliable and low-cost antenna system is required. PCB loop antennas are the most commonly used one.
