Create and Analyze AI-Based Microstrip Patch Antenna
This example shows how to create an AI-based microstrip patch antenna operating at 1.67 GHz, and calculate its bandwidth and resonant frequency.
Use the design
function with the ForAI
argument set to true
to create an AI-based microstrip patch antenna operating at 1.67 GHz. To use the ForAI
argument in the design
function you need a license to the Statistics and Machine Learning Toolbox™.
pAI = design(patchMicrostrip,1.67e9,ForAI=true)
pAI = AIAntenna with properties: Antenna Info AntennaType: 'patchMicrostrip' InitialDesignFrequency: 1.6700e+09 Tunable Parameters Length: 0.0862 Width: 0.1122 Height: 0.0018 Use 'showReadOnlyProperties(pAI)' to show read-only properties
Explore the design space by changing its length and width with values within the tunable range of these properties. You can get the tunable range of a property by using tunableRanges
function on the AI-based antenna object.
pAI.Length = 0.0855; pAI.Width = 0.113;
Calculate the absolute bandwidth of the antenna 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 the resonant frequency of the antenna.
fR = resonantFrequency(pAI)
fR = 1.7016e+09
Convert the AI-based microstrip patch antenna to a regular microstrip patch antenna.
pm = exportAntenna(pAI)
pm = patchMicrostrip with properties: Length: 0.0855 Width: 0.1130 Height: 0.0018 Substrate: [1x1 dielectric] GroundPlaneLength: 0.1795 GroundPlaneWidth: 0.1795 PatchCenterOffset: [0 0] FeedOffset: [0.0181 0] Conductor: [1x1 metal] Tilt: 0 TiltAxis: [1 0 0] Load: [1x1 lumpedElement]
Input Arguments
