External antennas certified with the WBZ450 module based on the PIC32CX1012BZ24032 device are listed on the WBZ450 Data Sheet. Refer to the High-performance 2.4 GHz Multi-protocol Wireless MCUs and Modules, supporting Bluetooth Low Energy and 802.15.4 protocols with 32-bit ARM® Cortex®-M4F, 2 Msps 12-bit ADC Data Sheet for more information. If any other antenna is chosen because of some end-product constraints, ensure that the antenna covers the desired frequency band, from 2.4 to 2.5 GHz.
If any other antenna (PCB antenna or Chip antenna) is chosen, follow the footprint and other layout recommendations as per the antenna data sheet/guidelines.
Ensure the dimension of the ground plane in the board meets the dimension requirement specified in the antenna data sheet. A reduced ground plane dimension might reduce the efficiency achieved with the same antenna.
Place the antenna impedance-matching components as close to the antenna pad as possible.
