The antenna assembly 30, which is arranged on one side of the display screen 20, is used to transform the guided wave propagating on the transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. It is the part of radio equipment used to transmit or receive electromagnetic waves.

In practical applications, the antenna assembly 30 can be divided into a transmitting antenna and a receiving antenna according to the nature of its work, and can be divided into communication antennas, broadcast antennas, television antennas, radar antennas, etc. according to its usage.
