I will design custom rf antennas and hfss simulations
HFSS Antenna Designer 5G, GNSS, Phased Arrays
I’m an RF & Antenna Design Engineer specializing in high-performance HFSS simulations. I build fabrication-ready antennas for 5G, GNSS, ISM, IoT, and phased arrays with a focus on real, measurable per...
About this Gig
Custom CP IoT/RFID Antenna Design | HFSS Expert
Stop losing link budget to poor polarization. I engineer high-performance, single-layer circularly polarized (CP) antennas optimized for global IoT deployments.
If you are building UHF RFID readers, LEO satellite terminals, or wireless sensor networks, you need pure circular polarization without the cost of multi-layer substrates.
Core Performance Metrics:
- Elite CP Purity: Sub-0.5 dB axial ratio (0.35 dB), approaching theoretical perfection.
- High Efficiency: 83.9% total efficiency using cost-effective FR4 substrate.
- Ultra-Stable: 0.07 dB gain flatness across the CP bandwidth for consistent read ranges.
- Global Adaptability: Dual-mode operation for EU (868 MHz) and North American (915 MHz) bands.
- Compact Integration: 100x100mm footprint for standard enclosures.
Deliverables:
- Ansys HFSS Source Files (.aedt)
- Manufacturing Files (Gerber/DXF)
- Technical Report (S11, Axial Ratio, Gain, 3D Patterns)

FAQ
1. Which software version of Ansys HFSS do you use?
I currently use Ansys Electronics Desktop 2024 R2. If you have an older version, please let me know so I can ensure compatibility or provide a generic format like .step or .dxf for the geometry.
2. Can you design for specific PCB substrates like Rogers or Taconic?
Yes. I can optimize the design for any material, including standard FR-4, Rogers (4350B, 5880, etc.), or Taconic. Please provide the substrate name and thickness (e.g., 0.8mm or 1.6mm) before we start.
3. Will the antenna be "ready to manufacture" when I receive it?
Absolutely. If you choose the Premium package, you will receive Gerber files (RS-274X). These are the industry standard and can be sent directly to manufacturers like JLCPCB, PCBWay, or Rogers for fabrication.
4. Do you provide a performance guarantee?
I guarantee that the simulation results (S11, Gain, Efficiency) will meet the agreed-upon specifications in the HFSS environment. Note: Real-world performance can vary slightly based on soldering and fabrication tolerances.
5. Can you design for 5G, mmWave, or UWB frequencies?
Yes, I have extensive experience designing for high-frequency applications, including sub-6 GHz 5G, 28GHz mmWave, and Ultra-Wideband (UWB). I ensure that mesh settings in HFSS are optimized for these high frequencies.
6. Do you offer revisions if the simulation doesn't meet my goals?
Yes, each package includes revisions. I will tune the dimensions and parameters until the simulation targets (like resonant frequency or bandwidth) are achieved.
