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...

AESAs are being used in these modern satcom systems to not only provide the ability to adaptively steer the antenna’s signal in the correct direction of its intended target but also to support multiple beams, which allows multiple users to be supported simultaneously. On...
L2 is thus needed to match the LNA to 50 Ωs (or other antenna impedance). Therefore, in order to match the MAX1470 to a 50Ω antenna, one only needs to cancel out the -j term. This can easily be accomplished with L2, which would need to be (at 315MHz). ...

The solution to this problem is the vertical stack. You put the two antennas at different heights. Thus, when one antenna is receiving out-of-phase signals, the other is receiving in-phase signals. If you combine these two antennas properly, you wind up with an average...
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...
A 3D polar plot of an antenna created using HFSS Gain— the direction in which the signal is strongest. Beam steering — the ability to steer the signal to a direction. Return loss — the amount of energy that is reflected to a source from an antenna. ...
