Polarization is the radiation characteristic that describes the spatial direction of the electromagnetic field intensity vector. Generally, the spatial direction of the electric field vector is regarded as the polarization direction of electromagnetic waves. The electromagnetic wave whose spatial orientation remains unchanged at any moment is called a linearly polarized wave. Taking the ground as the reference, the waves whose electric field vector direction is parallel to the ground are called horizontally polarized waves, and the waves perpendicular to the ground are called vertically polarized waves.

　　 According to the direction classification, GSM 4G antennas can be divided into directional 4G antennas and omnidirectional 4G antennas. According to the polarization method, GSM 4G antennas can be divided into single polarization and dual polarization. Different 4G antennas can be used in different occasions and different purposes. Different types of 4G antennas and different installation environments have different requirements and different installation methods for the planning of 4G antenna brackets, which deserve our attention.

　　 With the development of global communication affairs, as the primary method of personal communication in the future, wireless mobile communication technology has attracted great attention. How to eliminate co-channel interference and decline is a problem worthy of attention and consideration.

GPS is a terminal for positioning or navigation by receiving satellite signals. An antenna must be used to receive the signal. GPS satellite signal is divided into L1 and L2, the frequency is 1575.42MHZ respectively, among them L1 is the open civil signal, the signal is circular polarization. The signal strength is about -166dBW, which is a relatively weak signal. These characteristics determine the need to prepare a special antenna for GPS signal reception.
