Antenna Characteristics
Voltage Standing Wave Ratio (VSWR)
The VSWR graph shows the voltage standing wave ratio across frequencies centered around 433MHz. Key measurements indicate a VSWR of 2.0266 at 423MHz, 2.5118 at 433MHz, and 2.9973 at 443MHz.
Smith Chart
The Smith chart displays the impedance matching characteristics of the antenna. Data points are provided for frequencies 423MHz, 433MHz, and 443MHz, indicating impedance values and their corresponding positions on the chart.
Note: Tested in open air, data is for reference only.
Common Questions
- 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 performance.
- When there are line-of-sight communication obstacles, the communication distance will attenuate accordingly.
- Pay attention to the antenna's radiation pattern; incorrect antenna installation direction can lead to reduced transmission distance.
- Ground absorbs radio waves, so testing near the ground yields poorer results; it is recommended to increase height.
- Seawater strongly absorbs radio waves, making testing near the sea ineffective.
- If there are metal objects near the antenna or it is placed within a metal casing, the signal attenuation will be very severe.
- Poor impedance matching between the antenna and the communication device will result in poor communication performance.
