Contact your ITON representative for details. 2.2 Layout Considerations The CB1011-47P module should be placed at the location where the antenna is away from the power supply(i.e., Battery contacts) and any digital signal traces. There should be no key matrix membrane under the antenna area and the user’s hand should not be ITON Technology Corp. Page 5 of 8 CB1011-47P Bluetooth Low Energy Module over the antenna area when the keyboard is in use. The antenna keep-out area which is 5mm around the parameter of the module region is shown in the red dotted box. PCB material and signal traces should not be placed within the antenna keep-out area to assure optimum antenna performance.
