High isolation antenna structure on a ground plane

摘要

In accordance with one example, an antenna structure includes a three-dimensional dipole antenna having a first arm and a second arm that are suspended above a ground plane. One or more three-dimensional monopole antennas have corresponding monopole elements positioned in a plane of symmetry between the arms of the dipole. Other examples are disclosed.

1. An antenna structure comprising:
a three-dimensional dipole antenna having a first arm and a second arm that are suspended above a ground plane, wherein the three-dimensional dipole antenna shorts tangential electric fields within a plane of symmetry between the first arm and the second arm; and at least one three-dimensional monopole antenna, having at least one monopole element positioned in the plane of symmetry between the first arm and the second arm.
