Abstract:
1. An antenna comprising: a first patch antenna array having a number of co-planar conductive patches; a second patch antenna array having a number of co-planar conductive patches wherein the first patch antenna array and the second patch antenna array are each arranged to provide simultaneous dual polarization radiation patterns, the second patch antenna array sized to resonate at a wavelength that is smaller than a resonating wavelength of the first patch antenna array, the second patch antenna array positioned above and spaced from said first coplanar patch antenna array in a stacked array arrangement and the stacked array arrangement connectable to a single coaxial probe disposed below the first coplanar patch antenna array; and a feedline connected to feedpoints of the first and second patch antenna arrays, the feedline being oriented in a direction that is orthogonal to a plane of the first and second patch antenna arrays, extending from the single coaxial probe to the first patch antenna array and to the second patch antenna array, the feedline providing current flow to the first and second patch antenna arrays from the single coaxial probe, the current flow in the first and second patch antenna arrays providing the dual polarization radiation patterns at dual frequencies each corresponding to resonating wavelengths of the first and second patch antenna arrays respectively.
