5. the back side The rest of the PCB board should have a ground plane as large as possible preferably as large in one dimension as the antenna itself to make it act as an electrical counterweight to the antenna A quarter wavelength antenna on a PCB must be shorter than the wire antenna due to the influence of the dielectric material of the PCB The length reduction depends on the PCB thickness and material as well as how close to the edge of the board the antenna is placed Typical reduction is to 75 90 of the length in free space but exact length must be found empirically A 1 0 or 1 6 mm FR4 PCB with the antenna trace gt 1 cm from conducting obstacles normally reduces the length of a quarter wave antenna to about 2 4 cm If for space reasons the track is made even shorter than the resonating quarter of a wavelength the antenna should be matched to 50 ohms using a series inductor and a shunt capacitor The length of a quarter wave antenna is given in the table below 2450 2 9 2 25 2 7 PCB Layout Recommendations The recommended layout pads for the module are shown in the figure below All dimensions are in thousands of an inch mil The circle in upper left corner is an orientation mark only and should not be a part of the copper pattern 5a ThHou 5 Thoau 3 B Ka Ke S i eo IBA THOU IBBA Thou A PCB with two or more layers and with a solid ground plane in one of the in
