A 60 GHz miniaturised, low loss on‐chip bandpass filter (BPF) based on open‐loop resonators is presented. Overlapping of the BPF's resonators leads to miniaturisation and introduces a mixed coupling configuration. Moreover, its resonators are folded to minimise the size and the insertion loss (IL). H‐shaped defected ground structures are also used to reduce IL and to improve the out of band rejection. The measured IL, return loss, centre frequency, and bandwidth are 2.85 dB, 18 dB, 59 GHz and 15.5 GHz with a chip size of 368 × 262 µm 2 including pads.
