Introduction

RF antennas are an important element in modern electronic technology, allowing us to link electronic devices to wireless communication networks. The GD35-17P-NF is a right-hand circular polarized dipole antenna designed to use in beamforming networks with Global Navigation Satellite System (GNSS) frequency allocations. This type of antenna is used to send and receive digital data signals over terrestrial-based networks, such as cellular and 5G networks. In this paper, the application field and working principle of the GD35-17P-NF is discussed.

Application Field of GD35-17P-NF

The GD35-17P-NF, with its circular polarized radiation, is highly suitable for wireless communication systems. It has a wide frequency range of 1.575 - 1.721 GHz and an antenna efficiency of up to 98%. The antenna\'s low axial ratio means that it can be used for applications where there is a narrow frequency range or very close signal to noise ratio requirements. In addition, the antenna has good front to back radio ratio and excellent gain, making it suitable for applications such as satellite TV receivers, high-resolution remote sensing cameras, wireless networks, and area coverage in densely populated areas.

Working Principle of GD35-17P-NF

The GD35-17P-NF works by generating an electromagnetic field at the desired frequency range. The antenna consists of a metal dipole that is normal to the ground plane. The dipole is driven by two metallic conducting rods that are joined together at the top and bottom of the antenna to form a loop. The metallic loop and dipole structure serves as a resonant circuit and creates an electric field when excited with an alternating voltage. The electric field then interacts with the surrounding environment to create a magnetic field in the surrounding area. This magnetic field then interacts with the antenna’s metallic loop and dipole structure to induce a current in the antenna. This current is proportional to the electric field, and when combined with the antenna’s gain, is then transmitted outward in the form of a radio signal.

Conclusion

In conclusion, the GD35-17P-NF is an ideal antenna choice for applications that require a wide frequency range and high gain. Its circular polarized radiation allows it to be adapted to various GNSS frequency allocations with excellent performance. Its low axial ratio ensures that it works in applications that require a very close signal-to-noise ratio. Furthermore, its simple dipole design makes it easy to install and use.
