MIMO antenna assembly having reduced packaging size

摘要

A multiple input, multiple output (MIMO) antenna system includes an electrically conductive, substantially planar, ground reference and a plurality of antenna assemblies electrically connected to respective antenna feeds at respective connection points. The antenna assemblies extend on a first side of the ground reference and are formed from a conductive material. Each antenna assembly is rotationally asymmetric around an axis perpendicular to the ground reference and passing through the connection point.

1. A multiple input, multiple output (MIMO) antenna system comprising:
an electrically conductive, substantially planar, ground reference configured such that a maximum distance between any two points on the ground reference is less than one wavelength associated with an operating frequency of the antenna; and a plurality of antenna assemblies electrically connected to respective antenna feeds at respective connection points and extending on a first side of the ground reference, each of the plurality of antenna assemblies being formed from a conductive material and rotationally asymmetric around an axis perpendicular to the ground reference and passing through the connection point, each of the plurality of antenna assemblies comprising multiple conductive elements joined at a common apex and extending at an oblique angle relative to the ground reference.
