| Outline of Final Research Achievements |
In this document, a novel technology of the copper balls interconnection for millimeter-wave vertical transition in small packages is reported. Using this technology, a 60-GHz-band 2x2 beam-forming arrray antenna is also reported. Dual-feed patch antenna is used as an element antenna. The proposed antenna structure has two-substrate-stacking structure by the copper balls interconnection technology. The beamforming coverage area with gain exceeds 10 dBi was simulated and measured under the condition of 45 degree phase difference of feeding signal. We have confirmed normal operation of the proposed antenna because all channel signal was observed. Radiation pattern at 60 GHz in all 3-D direction was measured by 5 degree angle resolution. Beamforming area having over 10 dBi gain was evaluated.
