Non-uniform dielectric beam steering antenna
First Claim
1. A window having an integrated antenna, said window comprising:
- a pane of glass;
a radiation element supported by said pane of glass and having a first region and a second region;
a ground plane spaced from and disposed substantially parallel to said radiation element;
a first dielectric having a first relative permittivity and sandwiched between said first region and said ground plane;
a second dielectric having a second relative permittivity different from said first relative permittivity and sandwiched between said second region and said ground plane and disposed in a side-by-side relationship with said first dielectric; and
a feed line for providing an electrical connection to said radiation element, wherein a section of said feed line is disposed between said first dielectric and said second dielectric.

Abstract
A microstrip antenna for receiving an RF signal from a satellite includes a radiation element and a ground plane disposed substantially parallel to and spaced from the radiation element. A first dielectric and a second dielectric are sandwiched between the ground plane and the radiation element, in a side-by-side relationship. The first dielectric has a first relative permittivity and the second dielectric has a second relative permittivity different from the first relative permittivity. A feed line electrically connects the antenna to an amplifier. A section of the feed line is disposed between the first and second dielectrics. The antenna produces the effect of tilting a radiation beam from a higher to a lower elevation angle to achieve a higher gain at lower elevation angles.
