Radio frequency emissive display antenna and system for controlling

摘要

Apparatus and method improving the performance and allowing increased directionality and bandwidth via display-like software defined antenna. A surface is composed of an array of interconnected pixels which are capable of either becoming conducting or resistive allowing arbitrarily sized and shaped antenna structures. Each pixel is controlled by biasing the base which alters the conductivity on the top portion of the pixel. The specific pattern which is active on the display style antenna is based on the desired direction, frequency range, and waveform necessary for a required transmit and receive function.

主权项

1. An electronically directed antenna apparatus, comprising:
an antenna having an array of radiating pixels, each capable of being selectively switched between conductive and resistive states so as to permit and inhibit radio frequency radiation, respectively, therefrom; and an antenna control subsystem, wherein said antenna control subsystem cooperates with
said antenna,a radio frequency source; and a data source so as to enable said selective switching; wherein each of said radiating pixels further comprises
a pixel;a biasing element; anda column comprising a switching element;
wherein said biasing element
receives control signals and transmits state signals to said antenna control subsystem;causes said switching element to switch said pixel into conducting and non-conducting states; andcauses said switching element to vary the conductance of said pixel from a conducting to non-conducting states; andwherein said switching element is a sphere in physical contact with said pixel, said sphere having two hemispheres further comprising a conducting hemisphere and a non-conducting hemisphere.
