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. A device comprising:
a first conductive line in a first layer; one or more intermediate layers over the first layer; a second layer over the one or more intermediate layers; and a plurality of radiator antennas extending through the one or more intermediate layers, the plurality of radiator antennas being in communication with an antenna input, wherein the plurality of radiator antennas comprises:
a first pair of radiator antennas communicatively coupled by a second conductive line in the second layer, wherein the first pair of radiator antennas communicatively couples the first conductive line to the second conductive line;a second pair of radiator antennas communicatively coupled by a third conductive line in the second layer, wherein the third conductive line and the second conductive line are offset and substantially parallel in a top-down view; anda third pair of radiator antennas communicatively coupled by a fourth conductive line in the second layer, wherein the fourth conductive line is disposed on an opposing side of the second conductive line as the third conductive line, and wherein the second conductive line and the fourth conductive line are offset and substantially parallel in the top-down view.
