The S1851290P12NF is a highly advanced type of antenna used in telecommunications to transmit radio-frequency (RF) signals. The antenna consists of two compatible parts, the main body and the antenna head. The head is the portion connected to the radio equipment that sends and receives the RF signals, while the main body is the section that acts as the feeder and input/output for the RF signals. It has an impressive impedance match of 50 ohms and a frequency range spanning from 886MHz to 2700MHz.

Physical Properties

The S1851290P12NF is built with a casing made of aluminium. Its power handling capacity is rated for a maximum of 12 W, which is an impressive figure in comparison to similar antennas in the same range. It also has a standing wave ratio of < 1.3:1 and a vertical beam width of 90°. The gain of this antenna is depending on the height of the installation and frequency band but it can reach up to 8 dB in some cases.

Application Field and Working Principle

The antenna is typically used for GSM, 3G, 4G and LTE applications. Thanks to its impressive power handling capacity, it is particularly suitable for base station applications as well as outdoor and indoor permanent installations. The antenna ensures excellent radiating efficiency within the wide frequency range, guaranteeing high-quality transmissions. Given the impressive impedance match of this antenna, it is ideal for applications where noise reduction and energy savings are required.

The S1851290P12NF works with a dipole antenna structure, where the center is connected to the radio and the two poles are placed at a given distance so that RF signals transmitted from the radio spread radially over the surrounding area. The antenna is a broadband dipole, meaning it has a wide coverage area and is capable of engaging in multi-frequency transmissions. The large vertical beam width of 90 degrees of this antenna makes it particularly suitable for applications where large coverage area is desired.

Conclusion

The S1851290P12NF is a highly advanced type of antenna designed for telecommunications and ideal for base station applications as well as outdoor and indoor permanent installations. Its dipole antenna structure ensures excellent radiating efficiency within the wide frequency range with extremely low power losses. Coupled with its impressive power handling of 12W and the impressive vertical beam width of 90 degrees, the S1851290P12NF offers superior performances in RF transmission applications.
