Combinations of two or more dipole type antennas

Introduced: January 2015

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 > Imbricated or interleaved structures; Combined or electromagnetically coupled arrangements, e.g. comprising two or more non-connected fed radiating elements > Combinations of two or more dipole type antennas

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) > Imbricated or interleaved structures; Combined or electromagnetically coupled arrangements, e.g. comprising two or more non-connected fed radiating elements > Combinations of two or more dipole type antennas

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

IPC defines codes here since 2015.
