Antenna Design (Clone) – (تصميم الهوائي(نسخ

بسم الله الرحمن الرحيم

Step 1: Introduction

Antenna design is not an easy task.

To simplify things, we will CLONE the well known chineese module 2.4 GHZ nRF24L01+.

The nRF24L01+ is a single chip [2.400 – 2.4835GHz] transceiver suitable for ultra low power wireless applications.

Step 2: Documentation

Nordic semiconducteur provides a reference design for the nRF24L01+ chip. It prodives the recommended components too.

Cypress provides an extremely useful article to design a 2.4GHZ antenna.

Our PCB footprint is based on Cypress guidelines.

Step 3: PCB Antenna Footprint

I just followed the Cypress guidelines to draw the footprint. Becareful with dimensions (mils not mm).

Step 4: Schematics

I just reproduced the Nordic Semiconductor reference design in Kicad editor.

Step 5: PCB Design

Kicad is used to route this simple board.

Step 6: PCB Assembly

Becareful with the soldering iron.

Be patient.

Step 7: Enjoy

To test the newly designed Module with its integrated antenna, we used our “Yet Another Remote Controller Board“. Our module fits and replaces the totally cloned chineese equivalent.
