Introduction:

Antennas are an essential part of a radio communication system. Antennas have a history of nearly 150 years. 

In 1873, Maxwell proposed the unified electromagnetic field equations on the basis of his predecessors, and predicted the wave nature of electromagnetic phenomena.

 In 1887, Hertz proved the correctness of this theory with experiments. , In the experiment, the two earliest antennas in human history were used. The transmitting antenna was two metal rods with a length of 30cm. The terminals of the rods were connected to two square metal plates with a side length of 40cm. The receiving antenna was a metal round frame with a radius of 35cm. After that, people began to explore the practical application of radio waves.4G lte  Antenna,Wifi Antenna,2.4G indoor Antenna,etc.

 In 1897, Marconi realized wireless communication and proposed the antenna device.

After the 1920s and 1930s, with the discovery of the ionosphere and the invention of the three-stage electron tube, radio communication and broadcasting developed rapidly, and the functions and types of antennas were also continuously diversified and improved.5G Antenna,5G Base station antenna is popular now.
