Abstract: A switchable patch antenna comprises a planar conductor having an aperture (hole) formed in the middle of the planar conductor. Radiation of a sinusoidal signal is controlled by comparison of separate impedance values for two components that have separate impedance values. Each of the two components have one end coupled together at the terminal positioned at a center of the aperture and their other ends separately coupled to opposing edges of the aperture. A sinusoidal signal source is also coupled to the terminal positioned at the aperture's center. Further, when the impedance values of both components are substantially equivalent, radiation by the antenna of the provided signal and/or mutual coupling of other signals is disabled. Also, when an impedance value of one of the two components is substantially greater than the other impedance value of the other component, the provided signal is radiated and/or mutual coupling is enabled.

Abstract: A switchable dual polarization patch antenna with improved cross polarization isolation to concurrently radiate horizontally polarized signals and vertically polarized signals. A planar conductor is arranged with a first terminal and a second terminal that are vertically spaced on a portion of the planar conductor to radiate a component of a vertically polarized signal with zero degrees of phase shift from one of the two terminals and radiate another component of the vertically polarized signal having a 180 degrees of phase shift from the other of the two terminals. A hybrid coupler can provide the 180 degrees of phase shift. A horizontally polarized signal is radiated from a third terminal that is horizontally spaced on another portion of the planar conductor and coupled to a horizontally polarized signal source. The direction of the 180 phase shift for the first and second components of the vertically polarized signal may be selected.
