A miniaturised frequency selective surface (FSS) with λ 0 /7 × λ 0 /7 unit cell at the pass band centre frequency is presented for millimetre wave remote sensing. A resonant corner convoluted square ring (CCSR) is loaded with non‐resonant cross dipole (CD) for tri‐band spectral response. Rectangular patches integrated in the CCSR are used to optimise the coupling between the CD and CCSR to reject 50–60 GHz (B 1 ) and 170–195 GHz (B 3 ), and transmit 87–91 GHz (B 2 ). The FSS fabricated on 175 μm thick quartz with 3721 unit cells indicates polarisation and angle stable transmission response.
