Full Title

Full titles differ between systems:

IPC:

Arrangements for simultaneous operation of antennas on two or more different wavebands, e.g. dual-band or multi-band arrangements > Arrangements for providing operation on different wavebands > Individual or coupled radiating elements, each element being fed in an unspecified way > for different propagation modes > using a single feed point

CPC:

Arrangements for simultaneous operation of antennas on two or more different wavebands, e.g. dual-band or multi-band arrangements (combinations of separate active antenna units operating in different wavebands and connected to a common feeder system H01Q21/30) > Arrangements for providing operation on different wavebands > Individual or coupled radiating elements, each element being fed in an unspecified way > for different propagation modes (H01Q5/314 takes precedence) > using a single feed point

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

IPC defines codes here since 2015.
