Kindly help me to suggest the UWB Antenna Interface should we have to use matching N/w for UWB. please share the matching network and topology for UWB Antenna.
Choice of antenna depends largely on the application and size of the device.
The DW1000 chip has a 100Ω differential RF interface, to connect a single ended antenna, a wide-band balun is required. Recommended components for Balun and antennas are on page 39 in the DW1000 datasheet.
The DWM1000 module has both the balun and antenna integrated and might be a good starting point for development.
