#Antenna rf toolbox octave code

While I used a planar URA in this example, any standard or arbitrary geometry design can be constructed by defining the x, y, and z coordinates, as well as the element normal. Users can generate a MATLAB script for an antenna array design.

This code will allow you to reproduce the design and iterate as needed in the future.Ģ. Once the design is complete, MATLAB code can be generated directly from the app (Fig. Figure 1 shows the pattern for this array. I will use this antenna array, implemented with subarrays, in future examples. I have generated the design for a 64-element uniform rectangular array (URA) using the Sensor Array Analyzer app in Phased Array System Toolbox. Shown is the 3D directivity pattern for this array steered in azimuth and elevation. As the parameters are adjusted, the 2D and 3D patterns can be evaluated across the range of desired steering and angles and frequencies.ġ. In the first path, you iterate on the array parameters, such as element type, element spacing and location, weighting, and the subarray architecture. The antenna-array design for a MIMO system usually takes one of two paths. Modeling and simulation of antenna arrays can be used in your 5G, radar, and electronic-warfare (EW) workflows to reduce risk and hopefully eliminate rework. With this background in place, I will now focus on each section of the system design, starting with the antenna element and the array. I also demonstrated how hybrid beamforming can be used to simplify a hardware design, but still maintain the desired system performance.

In my previous blogs ( here, here, and here), I showed how beamforming can be used both to improve signal-to-noise ratio (SNR) and achieve higher channel capacity in multiple-input, multiple-output (MIMO) systems.
