Integrate antennas into RF systems using MATLAB Antenna Toolbox and RF Toolbox. Covers impedance matching network design (L/Pi/Tee topologies, evaluation parameters, Richards transformation), measured antenna creation (E-field, directivity-only, EmbeddedE, ffsReader import), RF propagation and site planning (txsite/rxsite, coverage, SINR, ray tracing, link budget), and SAR estimation (birdcage+Phantom, conformalArray+Custom3D, direct EHfields).

Prompt
I am evaluating RF exposure compliance for an antenna positioned near biological tissue operating at 900 MHz. Write a MATLAB script that defines the tissue material parameters and evaluation grid, calculates the 3D electric fields throughout the tissue domain, computes the point SAR distribution normalized to 1 W accepted input power, visualizes the slice heatmap of SAR with proper unit labels, and runs a power balance sanity check comparing efficiency against integrated loss.

Antenna Integration and Deployment
Integrate designed antennas into RF systems -- impedance matching, data exchange via
measuredAntenna, RF propagation/site planning, and SAR compliance -- using MATLAB
Antenna Toolbox and RF Toolbox.
When to Use
Impedance matching
Match an antenna to 50 ohm (or other impedance)
Improve return loss or VSWR
Design L, Pi, or Tee matching network
Convert lumped matching to distributed (Richards transformation)
Compare 2-element vs 3-element bandwidth
Measured antenna creation
Create a measuredAntenna from pattern data or simulation
Use an antenna with txsite/rxsite for propagation
Import antenna data from CST (.ffs) or HFSS (.ffd)
Steer a beam with phase shifts on a measured array
Use a measuredAntenna as element in a larger array
RF propagation and site planning
Compute signal strength, coverage, or path loss between sites
Analyze SINR, interference, or frequency reuse
Perform ray tracing for 5G/mmWave propagation
Determine link budget or link closure
Plan wireless network transmitter/receiver placement
SAR estimation
Compute SAR from an antenna near or inside biological tissue
Assess RF exposure compliance (FCC/ICNIRP limits)
Model a birdcage coil for MRI SAR analysis
Compute point SAR or mass-averaged SAR (1g/10g)
Design an implantable antenna and estimate SAR
When NOT to Use
Designing antenna elements or arrays (geometry, optimization) -- use matlab-design-antennas
Reflector antennas, reflectarrays, installed antennas, or RCS -- use matlab-analyze-antenna-structures
