RF Antennas

The YS4505 is an RF antenna designed for remote sensing applications. It has a low side lobe level and no noticeable interference, making it suitable for use in remote sensing applications.

The YS4505 is a quarter wave dipole antenna with an adjustable frequency range. It has a small size and lightweight construction, and it can be installed almost anywhere. It is a directional antenna with a gain of about 6 dBi and a basic radiation pattern. The YS4505 is usually supplied in single or dual polarization versions to accommodate different applications’ requirements.

Application

The YS4505 antenna is designed for use in remote sensing applications such as cellular and wireless communications, mobile surveillance, remote sensing and broadcasting. It is also suitable for residential and commercial premises, as well as for security and military applications. The YS4505 can be used in a variety of configurations, from point-to-point communication to mesh networks. Its low side lobe level and small size make it suitable for applications with limited space.

Working Principle and Features

The YS4505 works on the principle of balanced dipole antenna. The antenna is composed of two dipole elements, one in each arm. Each arm is composed of a conductor rod with a length of a quarter wavelength and an insulator rod between them. The dipole arms are then connected to the antenna feed line.

The YS4505 contains a DC shorting switch for switching between transmitting and receiving modes, a metal shell protection structure to guard against strong interference, and a heat dissipation hole to prevent the antenna from overheating. The antenna has a wide frequency range from 890 MHz to 5700 MHz, and it has a low gain, low VSWR andhigh linearity. It is also lightweight and easy to install.

Conclusion

The YS4505 is a high performance RF antenna designed for applications in remote sensing, broadcast and surveillance. It has a low side lobe level, small size and lightweight construction, and it is easy to install. The YS4505 is a quarter wave dipole antenna with a wide frequency range, low gain, low VSWR and high linearity, making it suitable for various applications.
