λ/4 printed monopole antenna for 2.45GHz
1. Preface
Taking the demand for small size, easy fabrication and low cost into account in the
development of low-power radio devices for short-range 2.4GHz applications, a quarter
wavelength monopole antenna implemented on the same printed circuit board as the radio
module is a good solution. A printed quarter wavelength monopole antenna is very easy to
design and can be tuned simply by slight changes in length.
This article presents basic guidelines on how to design such an antenna for use together with
the 2.4GHz transceiver and transmitter devices from Nordic Semiconductor.
The described antenna should be fabricated on standard 1.6mm, low cost FR4 printed circuit
board (PCB).
