Antenna Simulation for RF & Microwave Applications
Design, analyze and tune antennas on realistic 3D models, evaluating radiation patterns, matching and efficiency.
About Antenna Analysis
The EMWorks antenna solver helps you design and validate RF and microwave antennas directly on realistic 3D geometry. Simulate radiation patterns, impedance, bandwidth, efficiency and coupling so you can converge on the right antenna topology, feed and placement before building prototypes.
Key Capabilities
Full-wave 3D antenna simulation - Model patches, slots, dipoles, monopoles, horns, waveguide antennas, helicals, conformal antennas and more in a single RF & MICROWAVES environment.
Wideband and multiband analysis -Run frequency sweeps to study input matching, gain and radiation patterns across operating bands and guard bands.
Feed and matching structures - Analyze coaxial feeds, microstrip launches, waveguide feeds and matching networks through S-parameters, VSWR and Smith charts.
Integration with real products - Evaluate antenna performance in the presence of radomes, housings, PCBs and nearby metal/plastic structures to catch detuning early.
Parametric studies and design tuning -Vary geometric dimensions, material properties and feed positions to quickly compare antenna design options.

Output from EMWORKS' Antenna Analysis
The antenna solver reports the key RF and antenna metrics you need to evaluate performance and matching:
Radiation patterns (2D/3D): Gain, main lobe direction, beamwidth and sidelobes.
Gain, directivity and efficiency: How much power is radiated and how well it is focused.
Polarization and axial ratio: Linear or circular polarization quality for link compatibility.
Input impedance, return loss and VSWR: Impedance matching and power transfer quality.
Smith chart and S-parameters: Impedance behavior and port coupling in a system context.
Near- and far-field distributions: Field levels close to the antenna and in the far zone.
Frequency response: Variation of gain and matching over the operating band.
These outputs let you quickly confirm that an antenna design meets its performance targets and identify where to tune geometry, feeds or matching.
