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: Antenna Info AntennaType: 'patchMicrostrip' InitialDesignFrequency: 1.6700e+09 Tunable Parameters Length: 0.0862 Width: 0.1122 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 = patchMicrostrip with properties: Length: 0.0855 Width: 0.1130 Height: 0.0018 Substrate: [1×1 dielectric] GroundPlaneLength: 0.1795 GroundPlaneWidth: 0.1795 PatchCenterOffset: [0 0] FeedOffset: [0.0181 0] Conductor: [1×1 metal] Tilt: 0 TiltAxis: [1 0 0] Load: [1×1 lumpedElement]
Input Arguments
aiant
— AI-based antenna to calculate resonant frequency
AIAntenna
object
AI-based antenna, specified as an AIAntenna
object created using
the design
function.
Example: design(patchMicrostrip,1.67e9,ForAI=true)
.
Output Arguments
fR
— Resonant frequency in Hz
scalar in Hertz
Resonant frequency of the antenna for current values of tunable properties, returned as a scalar in Hertz.
Example: 6.1104e9
