Abstract :
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 ~0.32λ0. 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.
