About the difference between internal antenna and external antenna

Kunshan ruichengda electronics co., ltd. is a professional manufacturer of internal and external antenna, radio frequency line, electron wire harness, new energy wire harness. The company introduces the difference between internal antenna and external antenna, so that consumers can quickly understand the relevant knowledge of antenna.


About the difference between internal antenna and external antenna

Antennas convert high-frequency electromagnetic energy in transmission into electromagnetic waves in free space or vice versa into high-frequency electromagnetic energy in transmission lines.


In wireless transmission system, the design of antenna is particularly important. The quality of antenna directly affects the quality of communication.

With the development and evolution of wireless devices, the overbearing external antenna gradually turns to the implicit internal antenna. But, customers may ask, will wireless products with built-in antennas perform significantly worse than those with external antennas in terms of signal performance?
After many tests and statistics by the equipment manufacturer's laboratory, we found that in the same environment, there was no significant difference in wireless signal strength between wireless products with built-in antenna and those with external antenna, with the difference range of only 1-3%. And cut off more, the environment is more complex, the gap is less apparent. Therefore, we can conclude that the antenna's internal and external Settings have little impact on the coverage ability of wireless routers.

External antenna, mainly the psychological habits of most consumers. The more antennas the better the signal, the stronger the antenna the stronger the signal. The use of external antenna has virtually increased the fault nodes in network engineering, and the construction quality of incomplete antenna is also a potential hidden danger.

In the case of higher requirements on the shape and size of nodes, the external antenna needs to occupy a large piece of space, which may not be suitable for some applications. At the same time, external antenna reduces the acceptability of users in appearance, which has a certain impact on the commercialization of related achievements.

The design of the built-in antenna is not only limited in size but also in performance. There are some problems in the mechanical design of placing the antenna inside the equipment, such as the connection mode between the antenna and the equipment shell, the contact mode between the antenna feed point and the PCB board, and the design of the built-in antenna itself.

Ligowave, as a professional international wireless equipment manufacturer, has designed a series of wireless products with high gain built-in antenna by virtue of its strong technical advantages and engineering accumulation. The built-in antenna is installed in the equipment. It is mechanically rigid and not easy to be damaged. It has excellent mechanical performance, so it does not need to consider the uneven quality of the antenna to reduce network risks. The equipment antenna is highly integrated to ensure the perfect operation of the equipment.

External antennas have been replaced by internal ones, and most of the concerns about the performance of internal antennas are now gone. In terms of antenna efficiency, a key electrical parameter, a well-designed internal antenna can provide the same performance as an external antenna.
Compared with the external antenna, the internal antenna has the same performance, better appearance and stronger, so the transition from external to internal antenna has become an irreversible trend. About the difference between internal antenna and external antenna
