A novel type of wide‐band long‐wire antenna is presented for 60 GHz wireless on‐board chip‐to‐multi‐chip applications using a vertically polarised electric field. The psi‐shaped structure is devised to match the antenna input impedance to 50 Ω and to increase the front‐to‐back ratio by placing two bent 0.5 λ eff lines parallel to the original long‐wire antenna, which resulted in improved realised gain and can be directivity compared to those of a conventional baseline structure. The psi‐shaped long‐wire antenna shows a peak gain of 10.2 dBi, an end‐fire gain of 7 dBi, a 22% impedance bandwidth (52–65.2 GHz), and a 25.8% 3 dB gain bandwidth (56–74 GHz) in an area of 3.1 × 10 5 mm 2 . This study presents the proposed antenna for an on‐board chip‐to‐multi‐chip communication scenario for a distance of 20 mm, with a peak transmission gain of −19.5 dB and a 3 dB bandwidth of 11.8 GHz (=19.6%), which ranges from 55.4 to 67.2 GHz.
