Characteristics and model selection of 4G external antenna

When selecting suitable antennas for machines and equipment, first of all, the built-in or external antennas should be clearly adopted according to the product structure.
1、 Main features of 4G external antenna
High gain, little environmental harm, can be used as a standard, save development progress, occupy indoor space and endanger the beauty of goods
2、 Model selection of 4G external antenna
The covering direction of the data signal of the machine and equipment must be clear. The covering direction of the data signal is determined by the radiation source pattern of the antenna. According to the radiation source orientation of the antenna, the antenna is divided into omnidirectional antenna and directional antenna.
Suction cup antenna: the gain is relatively high, and the larger characteristic is that it contains a strong magnet suction cup. It is very convenient to install and fix it, but the suction cup must be adsorbed on the metal surface.
In the field of wireless modules, the suction cup antenna is often used in cooperation with the wireless antenna module, so as to improve the communication distance of the wireless module, such as wireless intelligent meter reading, vending machine, express box, vehicle radio, etc.
Copper rod sucker antenna: it is similar to the general whip sucker antenna, but its advantages over the whip sucker depend on the selection of all copper radiator with large diameter, low loss, high efficiency and wide network bandwidth.
It is applicable to data transmission radio stations with high relativity of performance regulations, map transmission with medium horizontal spacing, etc.
Glue stick antenna: it is the most common external wireless antenna with moderate gain and relatively cheap price. It is commonly used in wireless communication control module, wireless router, data transmission radio station, etc.
The wireless antenna with suitable specification and size can be selected according to the provisions of the installation indoor space. The selection of antenna specification is related to the gain. Generally, the longer the length of the same frequency band, the higher the gain.
FRP anti-corrosion antenna: among the omni-directional wireless antennas, the performance of FRP anti-corrosion antenna is more excellent. The core is all copper vibrator and balanced explosion-proof switch is selected, which is less harmful to the environment;
The casing is made of high-quality glass fiber reinforced plastic for anti-corrosion. It has very good three prevention characteristics and is well integrated into the extreme geographical environment. It is especially suitable for ultra long distance gateway, IP data signal masking, image transmission, etc.
The long-distance wireless communication environment is characterized by large area and small directional signal density.
Tablet antenna: high efficiency, small volume, convenient installation, capable of both gain and radiation source area. It can be covered by network signals in the room and tunnel construction, data signal transmission with medium horizontal spacing, map transmission and data signal passing through the wall.
Yagi antenna: very high gain, slightly larger volume and strong specificity. Pay attention to the orientation of the wireless antenna during application. It can be used for ultra long-distance data signal transmission, map transmission and direction finding.
Most cycle time Antennas: ultra wideband antenna. The network bandwidth cover is very wide, and the network bandwidth can reach 10:1. It is common that the data signal becomes larger, and the data signal of elevator car is covered all over the room.
