KiCad RFID Antenna PCB Design -- 2

PROJECT DESCRIPTION: I need a KiCad PCB designer to create three RFID antenna boards from scratch and deliver verified, JLCPCB-ready Gerber files. No existing files will be provided. The designer must create everything in KiCad based on the specifications below. These are rectangular spiral RFID reader antennas operating at 13.56 MHz (ISO 15693 protocol), used in a poker chip tracking system. Each board has a copper spiral on the front layer ([login to view URL]), a single return trace on the back layer ([login to view URL]), one SMA edge-launch connector, and one SMD tuning capacitor.

Spiral starts at the SMA connector on the left edge and ends at the inner terminal, connected to [login to view URL] via a through-hole via. [login to view URL]: Single straight return trace only, connecting the inner terminal via to the entry via near the SMA connector. No spiral on B.Cu. No other copper on B.Cu.

Entry point on the left edge. [login to view URL]: Single straight return trace only. No spiral. No other copper. BOARD 3 — POT-B ANTENNA (SMA on right edge) Identical to POT-A in every way except the SMA connector is on the right edge instead of the left edge. The spiral geometry is the same — only the connector position is mirrored.

Entry point on the right edge. [login to view URL]: Single straight return trace only. No spiral. No other copper. HOW THE 4 POT ANTENNAS ARE INSTALLED: The 4 POT antennas are arranged in a 2×2 grid to cover a 800×600mm pot area with no blind spots. POT-A boards go on the left column, POT-B boards go on the right column. Adjacent boards overlap by 20mm so the magnetic fields cover the gap between them. Each antenna connects to one port of the RD5224 RFID reader via SMA cable. DELIVERABLES — 3 ZIP files, one per board design: Each ZIP must contain exactly these 10 files: [login to view URL] ← spiral on front copper only [login to view URL] ← single return trace only [login to view URL] ← solder mask openings on pads [login to view URL] ← solder mask openings on pads [login to view URL] ← SMD pads only [login to view URL] ← empty [login to view URL] ← reference designators [login to view URL] ← empty or minimal [login to view URL] ← board outline only, no traces [login to view URL] ← drill file, Excellon format, metric MANDATORY VERIFICATION BEFORE DELIVERY: The designer must complete all three steps and deliver screenshots as proof: KiCad DRC — must show zero errors and zero warnings KiCad Gerber Viewer — screenshot confirming: [login to view URL] shows the full spiral [login to view URL] shows only the single return trace and via pads — nothing else Edge_Cuts shows only the board rectangle — no traces inside All other layers show only pads or are completely empty JLCPCB online Gerber viewer at [login to view URL] — screenshot confirming no short circuit warnings and no errors Files will not be accepted without all three screenshots. CRITICAL REQUIREMENT — most important point: The spiral must exist on [login to view URL] only. [login to view URL] must contain only one single trace connecting the two vias, plus the via pads and SMA pads. No copper features from [login to view URL] should appear on [login to view URL] or any other layer. This is a known KiCad export bug — the designer must verify each layer individually in the Gerber viewer before submitting. SKILLS REQUIRED: KiCad 6 or newer — mandatory Proven experience exporting Gerbers for JLCPCB fabrication Knowledge of RFID/NFC antenna PCB design Ability to calculate tuning capacitor value for 13.56 MHz resonance Must verify files in JLCPCB Gerber viewer before delivery PROJECT TERMS: Fixed price project Deadline: 3 days maximum Payment released only after JLCPCB Gerber viewer screenshots confirm zero errors on all 3 boards Do not start without confirming you have read and understood the [login to view URL] requirement above
