About this Gig
Stop guessing if your product will have good range. A bad antenna design kills battery life and connectivity.
I am an RF Design Engineer specializing in custom PCB Antennas for IoT and Embedded Systems. I don't just provide a theoretical simulation; I deliver a design that is ready for fabrication at JLCPCB, PCBWay, or Rogers.
My Expertise:
- IoT & Wearables: Compact PCB antennas (Inverted-F, Meander, Chip) for ESP32, nRF52, & STM32.
- Long Range (LoRa): Tuned 868/915 MHz antennas for LoRaWAN & Sigfox.
- High-Speed: 5G mmWave Arrays (28 GHz) & Wi-Fi 6E.
- Enclosure Tuning: I optimize designs to account for plastic casing detuning.
Why Choose Me?
Unlike standard simulation services, I design with Manufacturing Tolerances in mind. I ensure your impedance matches 50Ω on the physical board, not just in the software.
Deliverables: Fabrication Files: Gerber (RS-274X), DXF, & BOM.
Source Files: Ansys HFSS (.aedt) or CST Studio.
Mechanical: 3D STEP file for fit-check.
Report: S11, Gain, Efficiency & VSWR plots.

FAQ
Q: Do you account for the plastic enclosure/casing?
Yes! A plastic case can detune an antenna by 100-200 MHz. If you provide the 3D STEP file of your enclosure, I will import it into HFSS and tune the antenna specifically to work inside the casing.
Q: Will I receive the fabrication files?
Yes. In the Standard and Premium packages, I provide standard Gerber Files (RS-274X) and DXF outlines. You can send these directly to manufacturers like JLCPCB, PCBWay, or Rogers without any extra conversion.
Q: My board space is very small. Can you fit an antenna?
Absolutely. I specialize in miniaturized designs like Meander Line, Inverted-F (IFA), and Chip Antennas. I will optimize the geometry to get the best possible gain within your tight size constraints.
Q: Do you calculate the Impedance Matching Network?
Yes. I will provide the component values (Inductors/Capacitors) for a Pi or T-matching network to ensure your antenna matches 50Ω. This is crucial for maximum power transfer and range.
Q: Can you design for specific substrates like FR4?
Yes. Most IoT devices use cheap FR4. I optimize the bandwidth specifically to handle the high losses of FR4. If you need high performance, I can also design for Rogers (RO4350B, RO5880) or Taconic.
