Brief Introduction to S1718P12NF Antenna

The S1718P12NF is an internal antenna designed for RF applications in the typical frequency range of 2.4GHz to 5.8GHz. It is a surface mount (SMD) chip antenna and is part of the supplier’s Spider 718P family of antennas.

Features of the antenna include high efficiency, gain, typical polarization ratios, low voltage standing-wave ratios, and small dimensions. It has an approximate size of 0.4 inches in total width and length and a lightly-log-periodic design for beam-forming antennas.

With its compact size, the S1718P12NF antenna is ideal for embedded applications such as RF wireless cards, cellular phones, mobile, and land-line communication, radio monitoring, and sensitive applications. It is also mainly used in short-range applications, such as in Bluetooth and WLAN applications. In addition, it also has a wide application in GPS systems, such as for location tracking or navigation.

The antenna can also be used in remote sensing and meter-reading systems, such as in distant meters in electrical meters, gas meters, and water meters. Furthermore, it is also suitable for radio range applications, such as for cameras or security systems for fence monitoring and flood warning.

The operational principle of the S1718P12NF antenna is based on its internal design. Its radiation pattern is linearly polarized, and it is unidirectional, and therefore ideal for directional communications.

The antenna consists of a central conductor and two surrounding ground planes. The central conductor is connected to the radio-frequency feed point of the PCB. The two ground planes can be seen as the side walls of the radiating element. By changing the length and distance between the ground planes, the polarization and gain of the antenna can be adjusted.

The antenna is also designed to operate at many central frequencies in the range of 2.4GHz to 5.8GHz, producing a symmetrical and uniform radiation pattern. The beam width of the antenna is also narrow, making it suitable for directional applications.

The internal design of the S1718P12NF antenna provides very good impedance matching, making it suitable for SMD applications, as well as ensuring good signal strength as well as low power consumption. It also has a low EMC (Electromagnetic Compatibility) impact on the environment.
