第三章 天线特性
电压驻波比 (VSWR)
Graph Description: The Voltage Standing Wave Ratio (VSWR) graph illustrates the antenna's performance across a frequency spectrum. It shows that the VSWR remains below 2.0 for the most part, indicating good impedance matching. A specific value of 2.2686 is noted at 1.5750000 GHz.
史密斯圆图 (Smith chart)
Graph Description: The Smith chart provides a visual representation of the antenna's impedance. The data points cluster near the center of the chart, signifying effective impedance matching and minimal signal reflection at the operating frequencies.
Note: Antenna tested in air, bare.
第四章 常见问题
- Antenna frequency must match the wireless device frequency for optimal communication; otherwise, communication effects will be poor.
- Lower communication frequencies have longer wavelengths and better diffraction capabilities.
- When there are obstacles in the line of sight, the communication distance will be correspondingly attenuated.
- Pay attention to the antenna's radiation direction; incorrect installation orientation can lead to reduced transmission distance.
- The ground absorbs radio waves, resulting in poorer testing effects when close to the ground; raising the height is recommended.
- Seawater has a strong ability to absorb radio waves, making testing near the sea less effective.
- Metal objects near the antenna or placing it within a metal casing will cause severe signal attenuation.
- Poor impedance matching between the antenna and the communication device will result in poor communication performance.
