About the EKA-PiF-MIFA PCB

EKA-PiF-MIFA is an open source PCB design by Blaze-Pascal, published on GitHub under the MIT license. It is a 2-layer board measuring 49.7 × 49.3 mm, with 10 components from 5 distinct parts.

By type, the board carries 4 capacitors, 2 connectors, 2 antennas and 2 inductors.

It belongs with the iot & wireless, rf & radio and test & measurement designs in this gallery.

From the project

2.4 GHz MIFA trace antenna design and simulation. Modeled using Ansys HFSS with Optimetrics sweeps to optimize geometry. Implemented on a custom 2-layer KiCad PCB using a coplanar waveguide. Includes LiteVNA verification diagnostics and a calculated Pi impedance matching network.

Goal: Design, simulate, and measure a custom Meandered Inverted-F Antenna (MIFA) for the 2.4 GHz ISM band (Wi-Fi/Bluetooth).

Project Scope: - Literature Review: Studied reference designs and application notes from credible silicon manufacturers (TI, NXP). - RF Simulation: Modeled and optimized the antenna geometry using Ansys HFSS. - Hardware Prototyping: Exported the optimized geometry to KiCad, designed a 2-layer test PCB, and manufactured the prototype. - VNA Verification & Matching: Measured the physical antenna with a LiteVNA to verify simulation results, and designed a Pi matching…
