2.4GHz Band Gain Antenna Device Selection
Communication antenna device (antenna) is an energy converter that converts the guided wave propagating on the transmission line into an electromagnetic wave propagating in an unbounded medium, or vice versa. For designing a low-power, short-distance 2.4GHz wireless transceiver used in a radio frequency system, the design and selection of the antenna is an important part. A good antenna system can achieve the best communication distance. There are many types of 2.4GHz antennas, and different applications require different antennas.

Wireless Communications: Comparing Antennas and Wires
An antenna is just a wire? If you only know this, you are wrong! Antennas and wires are two critical but distinct components in wireless communications systems. They each perform important tasks, although their functions and operating principles are very different. Wireless communication is one of the main themes of intelligent civilization. In modern communication, wireless communication occupies an unshakable position. In radio communication systems, there is a vital part, that is, the antenna.

Rectifier circuit and filter circuit
In electronic circuits, most of them require a DC regulated power supply for driving. For example, in the amplifying circuit, on the one hand, the DC voltage regulator must establish a suitable static operating point for the circuit operation, and on the other hand, it must provide the required energy for the amplification of the signal.
