Abstract
Exemplary embodiments are provided of multiple-antenna systems with enhanced and/or good isolation and directivity. In one exemplary embodiment, a system generally includes a ground plane and two or more antenna elements coupled to the ground plane. The system also includes two or more low frequency isolators/reflectors and two or more high frequency isolators/reflectors coupled to the ground plane.
Claims20
A system comprising:
- a ground plane
- two or more antenna elements coupled to the ground plane;
- two or more low frequency isolators/reflectors coupled to the ground plane;
- and
- two or more high frequency isolators/reflectors coupled to the ground plane.
2 more elements
A system comprising:
- a ground plane including a circular portion having a circumference and a center;
- a plurality of antenna elements mounted to the ground plane along the circumference of the circular portion of the ground plane, the antenna elements equidistant from the center of the circular portion of the ground plane, the antenna elements spaced equally apart from each other such that a one hundred twenty degree (120°) arc is defined between mounting points of two adjacent antenna elements and the center of the circular portion of the ground plane;
- a plurality of low frequency isolators/reflectors in a spoked configuration centered at the center of the circular portion of the ground plane, such that the low frequency isolators/reflectors are positioned about the center of the circular portion of the ground plane and extend outwardly in a direction away from the center of the circular portion of the ground plane;
- and/or
- a plurality of high frequency isolators/reflectors, each placed between a corresponding one of the antenna elements and the center of the circular portion of the ground plane.
2 more elements
A multiple input multiple output (MIMO) antenna system, the antenna system comprising:
- two or more antenna elements;
- and
- two or more isolators/reflectors positioned relative to the antenna elements for increasing isolation between the antenna elements and for increasing directivity of each said antenna element in the direction of the sector that said antenna element serves.
