Abstract
An exemplary slot antenna having an antenna cavity that extends over multiple layers is provided. The slot antenna includes a reference conductive layer, a radiating conductive layer having at least one slot opening, one or more intermediate conductive layers disposed between the reference conductive layer and the radiating conductive layer, and two or more dielectric layers. The two or more dielectric layers include at least a first dielectric layer disposed between the reference conductive layer and the one or more intermediate conductive layers and a second dielectric layer disposed between the one or more intermediate conductive layers and the radiating conductive layer. Each of the one or more intermediate conductive layers includes at least one opening substantially devoid of conductive material. Due to its reduced footprint in the x-y plane, the multilayer slot antenna may be embedded in an integrated circuit package for use in a wireless device. The multilayer slot antenna also exhibits dual resonant frequencies under certain circumstances.
