Abstract: A dual band stacked patch antenna includes a first patch antenna arrangement coupled to and stacked on a substrate, the first patch antenna arrangement being configured to receive right hand circularly polarized signals in a first frequency band and a second patch antenna arrangement coupled to and stacked on the first patch antenna arrangement, the second patch antenna arrangement being configured to receive right hand circularly polarized signals in a second frequency band. A dielectric superstrate is stacked on the second patch antenna arrangement. Signals in the first and second frequency bands are transmitted to the first and the second patch antenna arrangements through the dielectric superstrate. A single signal feed is shared by both the first patch antenna arrangement and the second patch antenna arrangement and acts to transmit electrical signals representative of the right hand circularly polarized signals in the first and the second frequency bands.

Abstract: An antenna assembly configured to be mounted on a glass structure. The antenna assembly comprises a multilayer structure comprising i) a superstrate layer comprising a thin dielectric material; ii) an antenna layer on which the superstrate layer is disposed, the antenna layer comprising an electrically conducting material; and ii) a first substrate layer on which the antenna layer is disposed. The antenna assembly further comprises a housing in which the multilayer structure is disposed. The housing is adapted for attachment to a surface of the glass structure. A dielectric characteristic of the superstrate layer compensates for a dielectric characteristic of the glass structure in order to reduce the variability of the operating frequency of the antenna assembly.
