Phased Array Systems

This page contains improvements to the AWR Design Environment for phased-array designers.

License Requirements: VSS-250 or greater and the 5G library (W5G-100) or the Radar Library (RDR-100)


Efficiently simulate extremely large phased arrays.

Design 5G MIMO systems, including RF and beamforming architectures.

Discover the impact of phased arrays on overall system performance.

Utilize yield analysis or optimization tools to evaluate and improve designs.


Phased Array Enhancements

Opens the Phased Array (PHARRAY_F) example, tiles out the main graphs and simulates. All of the phased array enhancements are shown in this view, but they can be displayed individually using the demo buttons below.


Response

This demo illustrates using the PHARRAY_F model to evaluate the response of a phased array while taking into account radiation patterns and RF links of each element.

  1. This demo uses Phased Array Response System Diagram.
  2. Note how array patterns for various power levels differ, showing how they are affected when RF links of array elements are pushed closer to compression. Since a non-uniform gain taper is used, some links are pushed into compression earlier than others, resulting in a distorted array response.

Modulated Signals

This demo illustrates passing modulated signals through the PHARRAY_F model.

  1. Note that spectral measurements are made on the Phased Array with Modulated Signals System Diagram.
  2. The simulation is a wideband signal contructed according to the Verizon 5G Tech Forum specifications, and measured for various power levels. These results show how the signal is compressed when passed through the phased array.

Yield

This demo illustrates the impact of gain and phase variation on the array antenna pattern.

  1. The yield analysis is done with the Phased Array Yield Analysis System Diagram.
  2. Random fluctuations are introduced on the gain and phase offsets of the phased array, and the corresponding array response is plotted. Results show how the side lobes of the response are affected by these fluctuations. The response without gain/phase imperfections is also plotted for reference.
