Summary:
60 GHz band array antenna is one of the key technologies to obtain a high antenna gain for ultra-high speed data rate short range communication. We propose a novel 2×4 dipole array antenna which enables 2-dimensional (azimuth/elevation) beam scanning in the horizontal direction of the substrate for beamforming application. To realize appropriate distance between antenna elements, several organic substrates are stacked by employing the copper ball interconnection technology. The antenna elements are placed on top and bottom substrate. 6 sets of fixed beam dipole array antennas are designed,fabricated, and evaluated. The measurement variations of element distance in the vertical direction for 6 samples are smaller than approximately 30 μm. By CT scan, it is confirmed that the signal line and ground between substrates are properly soldered to the copper balls. The measurement results of radiation pattern of fabricated dipole array antennas agree with the simulation results. These results show that the array antenna using multi stacked organic substrates structure can be repeatedly fabricated with sufficient accuracy.
