Abstract

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.
