Dual polarization patch antenna system

A method for controlling radiation of signals by an antenna, comprising:

• providing a planar conductor that is electrically insulated from a separate grounded plane;
• employing a first signal source to provide a vertically polarized signal, wherein a first component of the vertically polarized signal is provided with zero degrees of phase shift to a first terminal and a second component of the vertically polarized signal is provided with 180 degrees of phase shift to a second terminal, wherein the first terminal and the second terminal are vertically spaced and separately located away from each other on a portion of the planar conductor;
• employing a second signal source to provide a horizontally polarized signal to a third terminal, wherein the third terminal is horizontally spaced on another portion of the planar conductor and separately located away from the first terminal and the second terminal;
• wherein the separate vertically spaced locations of the first terminal and the second terminal and the 180 degrees phase shift difference between the first and second components of the vertically polarized signal and provides cross polarization isolation when the vertically polarized signal and the horizontally polarized signal are concurrently radiated by the antenna.

A non-transitory computer readable media that stores instructions for controlling radiation of signals by an antenna, wherein execution of the instructions performs actions, comprising:

• providing a planar conductor that is electrically insulated from a separate grounded plane;
• employing a first signal source to provide a vertically polarized signal, wherein a first component of the vertically polarized signal is provided with zero degrees of phase shift to a first terminal and a second component of the vertically polarized signal is provided with 180 degrees of phase shift to a second terminal, wherein the first terminal and the second terminal are vertically spaced and separately located away from each other on a portion of the planar conductor;
• employing a second signal source to provide a horizontally polarized signal to a third terminal, wherein the third terminal is horizontally spaced on another portion of the planar conductor and separately located away from the first terminal and the second terminal;
• wherein the separate vertically spaced locations of the first terminal and the second terminal and the 180 degrees phase shift difference between the first and second components of the vertically polarized signal and provides cross polarization isolation when the vertically polarized signal and the horizontally polarized signal are concurrently radiated by the antenna.
