Promising preliminary results are presented for an isolator and a 4-port circulator in novel fin-line structures in the frequency range 26.5 - 40.0 GHz. The basic configuration is a ferrite-loaded coupled-slot fin-line with the ferrite magnetised parallel with the direction of propagation. It is suggested that such structures would also be suitable for higher frequencies.
