Testing phased array antennas with high-accuracy calibration requires spherical antenna pattern measurements. Learn how to use a vector network analyzer and signal generator, compact antenna test range, and advanced calibration and test software to verif
To test your antenna’s gain, you will need a reasonably open lab space, with distance from any RF reflective objects like metal furniture. You will also need a source and a receiver, which could be a separate signal generator and spectrum analyzer, or a vector network analyzer. Sources suc...
A look at the S11 with the help of the network analyzer will allow this to be tuned even better. Set the test port power of the network analyzer to -30dBm so as not to saturate the input stage.Figure 2shows the S11 of a not so perfectly matched board. The S11 is tuned to 355MHz...
A second test has been performed to show the impact of the antenna desense on a real application. A home gateway, which works at a 2.4 GHz and 5 GHz WiFi dual frequency was used. This box communicates with a computer (number 1), which analyzes the WiFi signal received using a software...
Even if there aren’t any, we recommend you restart your router just to give it a fresh start. Get a better antenna for your router: In addition to learning how to increase WiFi signal strength using the above-described method, you should check if your router has a removable antenna. If...
Moving the wireless device to a different spot. Even a couple of feet can make a huge difference in WiFi signal strength. Even readjusting the antenna might help. Adding a WiFi extender to your network. Getting a Powerline adapter. These adapters are very efficient for larger spaces with thi...

天线增益是如何获得的?How the antenna gain is obtained? A. 在天线系统中使用功率放大器Use a power amplifier in the antenna system B. 使天线的辐射变得更集中Focus the radiation of antenna C. 使用高效率的天馈线Use an efficient antenna feeder D. 使用低驻波比的设备Use a device with a low ...
1. Passive Antenna Testing Passive antenna testinguses an OTA test method where the test signal is fed directly to the antenna array, and the outputted RF signal is then measured. The DUT is typically only the passive antenna array without any active radio unit. This makes passive antenna tes...
