What are the important parameters of ceramic antenna?
1. VSWR voltage standing wave ratio
The VSWR is less than 2.0, and the VSWR at the working frequency point is less than 1.5. If the VSWR is too large, the communication distance will be shortened, and the reflected power will return to the power amplifier part of the transmitter, which is easy to burn the power amplifier tube and affect the normal operation of the communication system.
Generally, the electrical parameters of ceramic antenna are related to the working frequency. To ensure the allowable frequency variation range of electrical parameters is the working bandwidth of ceramic antenna. Generally, the working bandwidth of omnidirectional ceramic antenna can reach 5-8% of the working frequency range, and that of directional ceramic antenna can reach 3-10% of the working frequency range.
Gain is one of the main indexes of ceramic antenna. It is the product of direction coefficient and efficiency, and it is the performance of the size of the wave radiated or received by the ceramic antenna. The choice of gain depends on the requirements of the system design for the coverage area of the wave. In short, under the same conditions, the higher the gain, the farther the distance of the wave propagation.
4. Noise figure
The larger the coefficient is, the larger the noise will be, which indicates that the more noise will be added in the transmission process, reflecting the unsatisfactory characteristics of the device or channel. When the noise figure of the amplifier is low, the noise figure of the amplifier is usually expressed by the noise temperature (T).
