AIAntenna

Enable catalog antenna elements for AI-based design space exploration

Since R2023b

Description

The AIAntenna object lets you convert a regular antenna from the antenna catalog to an AI-based object and leverage AI-based analysis for rapid characterization and design space exploration. Using AI-based antenna models over conventional full-wave solvers significantly reduces the simulation time required to fine-tune the antenna to meet your design goals.

Creation

You can create an AIAntenna object for the supported catalog elements by setting the ForAI name-value argument to true in the design function. This object has 2 fixed read-only Properties and catalog element specific dynamic properties which are either tunable or read-only. See the individual catalog element pages for details on these dynamic properties.

Examples

Create and Analyze AI Model Based Microstrip Patch Antenna

This example shows how to create an AI model based microstrip patch antenna operating at 1.67GHz, and calculate its bandwidth and resonant frequency.

Create AI Model based Microstrip Patch Antenna

Use the design function with ForAI flag set to true to create an AI model based microstrip patch antenna operating at 1.67 GHz.

pAI = design(patchMicrostrip,1.67e9,ForAI=true)

pAI = 
  AIAntenna with properties:

                    Height: 0.0018

Show read-only properties

Vary its length and width.

pAI.Length = 0.0855;
pAI.Width = 0.113;

Analyze Microstrip Patch Antenna

Calculate its bandwidth and its lower and upper bounds.

[absBW,fL,fU,matchingStatus] = bandwidth(pAI)

absBW = 2.3422e+07

fL = 1.6679e+09

fU = 1.6913e+09

matchingStatus = categorical
     Matched 

Calculate its resonant frequency.

fR = resonantFrequency(pAI)

fR = 1.7016e+09

Convert the AIAntenna to a regular microstrip patch antenna.

pm = exportAntenna(pAI)

pm =
