LTE (4G) antennas

Long-Term Evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. It increases the capacity and speed using a different radio interface together with core network improvements.

The directionality of the 4G antenna is presented by a directional (radiation) diagram. The radiation diagram is really three-dimensional, but in practice it is represented in most cases by a 2D spatial section in the vertical or horizontal plane. From this diagram, a very important parameter called the 4G antenna radiation angle is determined. It is the angle of the radiation maximum, which is defined by two values, which correspond to a decrease of the maximum field strength by 3 dB.

LTE antenna omnidirectional antenna radiates signals in all directions, providing a 360-degree coverage area. This type of antenna is commonly used in scenarios where multiple devices need to connect to the LTE network from various directions, such as in public spaces or small offices.

Another type is the directional LTE antenna, which focuses its signal in a specific direction, offering a more concentrated and extended coverage range. This type is often used in outdoor settings to establish point-to-point or point-to-multipoint connections over longer distances, ensuring reliable connectivity in remote or rural areas.
