What is the performance of Beidou antenna? What are the performance indicators?

Today, Beidou antennas are used more and more in our lives. For example, personal location services can provide directions when entering an unfamiliar place using a mobile phone or vehicle satellite navigation device equipped with a Beidou antenna. It is precisely because of this that there are many Beidou antenna manufacturers. What are the specific performance indicators of this antenna?

1. Consideration of input impedance

The input impedance is the ratio of voltage and current at the supply point of the Beidou antenna. Generally speaking, the input impedance of the Beidou antenna is a complex number, and the real part is called the input resistance. In addition, the input impedance of the Beidou antenna is related to the shape, size, supply point location, operating wavelength and surrounding environment of the antenna. Therefore, Beidou antenna manufacturers need to pay attention to this when producing antennas.

2. Understand performance through direction diagram

In terms of performance indicators of the antennas produced by current Beidou antenna manufacturers, the pattern is a graphical representation of the direction function, which intuitively describes the distribution of electric field strength in space, and uses the commonly used general power lobe width to represent the width of the pattern. The Beidou antenna pattern is determined in long-distance areas, so it is also called a long-range pattern.

3. Polarization characteristics of the antenna

The polarization characteristics of the Beidou antenna are defined by the spatial direction of the electromagnetic wave emitted by the antenna from the emission direction to the electric field intensity vector, which describes the parameters of the spatial direction of the electromagnetic wave vector emitted by the Beidou antenna. There is a certain relationship between the electric field and the magnetic field, so the space is generally pointed in the polarization direction of the electromagnetic waves radiated by the Beidou antenna.

To followBeidou antenna manufacturer, when considering the performance indicators of this antenna, you will find that it is mainly through these indicators that you can understand the performance of the antenna.
