Embodiment Construction

[0033] Various embodiments of the invention generally relate to structures of radiating elements and their feed lines disposed on LCD structures, as well as scanning antenna arrays and systems incorporating such structures. In the context of the various embodiments described, the LCD structure used for the antenna of the present invention need not include a light source. For example, various embodiments described herein may be used in conjunction with fixed and / or mobile platforms. Of course, the various antennas and techniques described here may have other applications not specifically mentioned here. Mobile applications may include, for example, mobile DBS or VSAT integrated into ground, sea or air vehicles. Various techniques may also be used for two-way communication and / or other receive-only applications.

[0034] FIG. 3A shows an example of a scanning antenna according to an embodiment of the present invention, and FIG. 3B shows a cross-section of the enlarged region i...

Abstract

An antenna and antenna array are provided. A radiating elements and corresponding feed lines are provided over a variable dielectric constant material sandwiched between two panels. The sandwich may be in the form of an LCD. The dielectric constant in a selected area under the conductive line can be varied to control the phase of the radiating element. The dielectric constant in a selected area under the radiating element can be varied to control the resonance frequency of the radiating element. The dielectric constant in a selected area under the conductive line can be varied to also control the polarization of the radiating element.
