About this Gig
Antenna design, 3D EM simulation & optimization patch to phased arrays.
Antenna won't resonate, won't hit bandwidth, or won't simulate right? I'm an RF/microwave engineer doing antenna design and 3D EM simulation from PCB patches to phased arrays and metamaterials.
WHAT YOU GET:
- Designed and simulated in HFSS, CST or ADS
- S11, VSWR, gain, directivity, efficiency all verified
- 2D & 3D radiation patterns
- Impedance matching where needed
- Fabrication-ready dimensions and layout
- Clean report for fab house, thesis or publication
TYPES:
Patch Dipole & monopole PIFA Slot Horn Helical Yagi Fractal Metamaterial & EBG DRA MIMO Phased arrays mmWave Wearable
BANDS:
VHF/UHF ISM 2.4/5.8 GHz WiFi GPS/GNSS LTE/5G sub-6 mmWave X/Ku/Ka Radar RFID UWB
WHY WORK WITH ME:
- Realistic engineering no fake specs
- Reproducible, trustworthy results
- Journal / thesis-ready plots and documentation
BEFORE ORDERING;
Send frequency, application, substrate/material, size limit and target gain/bandwidth. Unsure which package fits? Message me custom work welcome.
FAQ
Which simulator do you use?
ANSYS HFSS and CST Studio Suite primarily; ADS for matching networks and FEKO for large structures. Tell me if your university/company requires a specific one.
Can you design for my exact frequency and substrate?
Yes. Send frequency (or band), substrate material (e.g. FR4, Rogers RO4350B, RT/duroid), thickness, and any size constraints — the design will be built around them.
Do you provide fabrication files?
On Standard and Premium, yes dimensioned drawings and layout. Gerber/BOM is a paid extra on Basic.
Will the antenna work after real fabrication?
Simulation is highly accurate when the model and material parameters are correct, but real-world results depend on the fab tolerance, connectors, and enclosure. I include tolerance discussion in Premium and can help tune against your measured data.
What if you can't reach my required gain/bandwidth?
I'll tell you honestly before or during the order and propose a realistic alternative (larger ground plane, different substrate, array, etc.). I don't promise specs physics won't give.
Do you deliver the HFSS/CST project files?
Source files are a paid extra the default delivery is the report, plots, and dimensions.
Can you match a paper's design?
Yes, I can reproduce and verify a published antenna design, or modify it for your frequency/application.
Do you write the thesis/report text?
I deliver a technical engineering report. A separate IEEE-style writeup is available as an extra.
