Description
Summary:Package-integrated highly directive dipole antenna and dipole array with an original feeding technique are presented. The proposed design features excitation of low-cost organic-based substrate elevated directive dipoles with vias. A miniature substrate embedded feed network is provided for direct via interconnection between the antenna and a chip embedded in the same stack-up. The simulated single dipole (10 × 10 × 0.635 mm 3 ) exhibits more than 11 GHz bandwidth (56 to 67+ GHz), 7.83 dBi peak directivity, and 91.7% efficiency. A prototype of an 8-element dipole array (22 × 11 × 0.635 mm 3 ) is measured and exhibits 8 GHz bandwidth (56.6 to 64.6 GHz), 15.1 dBi peak gain at 61 GHz, and 75 to 83% estimated efficiency.
