Abstract
Antenna polarization diversity enhances the MIMO performance of multiple antennas, especially when the multiple antennas do not exhibit significant placement diversity. An antenna assembly provides selectable antenna polarization in the antenna assembly on a ground plane. An antenna element of the antenna assembly drives a first electrical configuration with a radiofrequency signal to radiate with a polarization predominately in a first direction of propagation. The antenna assembly is selectively modified from the first electrical configuration to a second electrical configuration, responsive to driving the antenna element of the antenna assembly in the first electrical configuration. The antenna element of the antenna assembly is driving in the second electrical configuration with the radiofrequency signal to radiate with a polarization predominately in a second direction of propagation, responsive to selectively modifying the antenna assembly from the first electrical configuration to the second electrical configuration.
