3D antenna for integrated circuits

摘要

An antenna comprises a first layer having a first redistribution layer, a feeding line, a ground connection element, and one or more antenna inputs. The antenna also comprises one or more intermediate layers over the first layer. The antenna further comprises a second layer having a second redistribution layer over the one or more intermediate layers. The antenna additionally comprises one or more through vias arranged to communicatively couple the second redistribution layer and the first redistribution layer. The antenna also comprises a short element. The antenna further comprises one or more radiator antennas within the one or more through vias, the one or more radiator antennas being in communication with the one or more antenna inputs by way of the feeding line.

1. An antenna comprising:
a first layer comprising a first redistribution layer, a feeding line, a ground connection element, and one or more antenna inputs; one or more intermediate layers over the first layer; a second layer comprising a second redistribution layer over the one or more intermediate layers; one or more through vias arranged to communicatively couple the second redistribution layer and the first redistribution layer; a shorting element; and a plurality of radiator antennas within the one or more through vias, the plurality of radiator antennas being in communication with the one or more antenna inputs by way of the feeding line, wherein the plurality of radiator antennas comprise:
a first pair of radiator antennas coupled by a first portion of the second redistribution layer, wherein the plurality of radiator antennas is arranged as a first row of radiator antennas comprising the first pair of radiator antennas communicatively coupled by the first portion of the second redistribution layer and configured to be a patch wall communicatively coupled to the feed line at least by way of a primary radiator antenna, the primary radiator antenna being one of the radiator antennas of the first row of radiator antennas; anda second pair of radiator antennas coupled by a second portion of the second redistribution layer, wherein the second portion of the second redistribution layer is adjacent to and substantially parallel with the first portion of the second redistribution layer in a top down view, wherein the plurality of radiator antennas is further arranged as a second row of radiator antennas comprising the second pair of radiator antennas offset from the first row of radiator antennas, the second row of radiator antennas being communicatively coupled by the second portion of the second redistribution layer and configured to be a ground wall communicatively coupled to the ground connection element by one or more of the radiator antennas in the second row of radiator antennas.
