Low cost PCB antenna for 2.4GHz radio:
Meander design

Introduction
This application note is dedicated to the STM32W108 product family from
STMicroelectronics.
One of the main reasons to use a PCB antenna is the reduced overall cost of the radio
module. Well designed and implemented PCB-printed antennas have a similar performance
to the SMD ceramic equivalence. In general, the footprint for a ceramic SMD antenna is
smaller than that for a PCB-printed variant. For a PCB-printed antenna solution, the
increased size of the PCB in relation to space required for the antenna means that the radio
module is larger cost of the PCB increased. The increased cost of the PCB is smaller and
less expensive than a SMD ceramic antenna.
The STM32-RFCKIT RF control kit is based on an STM32W108xx RF microcontroller. It
implements a PCB-printed antenna to perform RF communications.
