RF antennas are an important form of transmission and reception of wireless signals. The YB1503 antenna is one type of RF antenna that is found in a variety of applications. In this article, we will look at the application field and working principle of the YB1503 antenna.

Application Field

The YB1503 is a directional antenna that is commonly used in residential and corporate environments. It typically operates in the 1290-1330 MHz range and is ideal for networking applications such as WiFi, wireless data communications, and point-to-point long-range communications. It is also well suited for U/VHF communication in surveillance systems and in telemetry for telecommand systems.

The YB1503 is widely used in many industries such as agriculture, defense, industrial, and commercial fields. In agriculture, for example, it is often used for field data collection and wireless seed and robot control. In the defense sector, it is commonly used in defense communication, surveillance, and detection. In industrial applications, it is used for controlling robots, monitoring production, and tracking mobile equipment. In the commercial sector, it is typically used for long-range communication, security, and surveillance.

Working Principle

The YB1503 antenna works on the principle of directional antenna radiation. This means that the antenna radiates energy in a certain direction when it is energized by a specific frequency. This radiation helps increase the signal strength for the targeted direction. The directional radiation of the YB1503 is achieved by its design which comprises of four dipoles that are arranged in a rectangular pattern.

The four dipoles are fed with a 50-ohm coaxial feed. Two of the dipoles are fed in-phase and the other two dipoles are fed out-of-phase. This arrangement results in the antenna radiating a linear polarization, which is ideal for wide-area coverage. Additionally, the four dipoles are fed from four different points on the radiator, which helps reduce the lobe size and side lobes of the antenna.

In terms of frequency performance, the YB1503 has a gain of 9.9 dBi, a return loss of 10 dB, and an efficiency of 90 percent. It also has a beamwidth of 40°, which makes it suitable for wide-area coverage. Additionally, the YB1503 is relatively lightweight at only 8kgs and is easy to install.

Conclusion

In conclusion, the YB1503 is an excellent choice for many applications including WiFi, wireless data communications, and point-to-point long-range communications. It operates in the 1290-1330 MHz range and is designed with four dipoles that are arranged in a rectangular pattern. The antenna radiates a linear polarization with a gain of 9.9 dBi, a return loss of 10dB, and an efficiency of 90 percent. It also has a beamwidth of 40°, making it well-suited for wide-area coverage. The YB1503 is lightweight and easy to install and calibrate.
