Hi all,
I'm working on the IWR6843ISK board and would like to do some modification on the antennas requested by our customers. I wonder that what is the main reason for designing the two shunt stub in the GCPW feed line (Is it a matching network, or some bandpass filter), and why we use ground frame to cage the antenna (I assume that's for mutual coupling & surface wave propagation).
Thanks in advance
Jeric
