A 1 × 4 double‐sided dipole antenna array with an associated Butler matrix beamforming network was designed and implemented at 60 GHz using glass‐based integrated passive device (IPD) technology. Owing to the chip area limitation, the spacing between the antenna elements is ∼0.32 λ 0 . Experimental results show that beams are successfully generated in the −62°, −23°, 22° and 50° directions, with total array gains of 2.5, 3.8, 4.3 and 3.0 dBi, respectively, which agree with simulation predictions. This successful demonstration provides a feasible solution for 60 GHz radio in heterogeneous system‐in‐package (SiP) integration.
