摘要： Generalized non-limiting embodiments include employing a dipole antenna and/or a half slot antenna. Each of the antennas constitutes three mutually perpendicular radiating elements to achieve good isolation and low antenna signal correlation between the three ports. In one generalized non-limiting embodiment the antennas are fabricated on FR-4 epoxy boards. Experimental results show that the antennas resonate a reasonable frequency and have a desired mutual coupling. In addition experimental results for the diversity performance and the MIMO channel capacity are also provided for these antennas and these results show that the herein described antennas offer good diversity gain and the channel capacity can be increased by as much as three times by using these antennas over conventional antennas.

摘要： A system for reducing unwanted signals comprises a ground plane, a first active component disposed so as to cause signals in the ground plane, a second active component disposed so as to cause signals in the ground plane, wherein the ground plane provides a path for the signals from the first active component to affect the second active component and for the signals from the second active component to affect the first active component, and a filter element configured as a pattern in the ground plane receiving and attenuating the signals from each of the first and second active components.

摘要： Compact 24-port and 36-port multiple-input-multiple-output (MIMO) antenna designs and methods of construction based on a cube-like structure are provided. The antennas can be implemented with slot antennas distributed on the edges and faces of cubes. According to various embodiments of the disclosed subject matter, both spatial and polarization diversity can be achieved and average mutual couplings among the ports better than −20 dB can be achieved providing good channel capacity in MIMO applications. The disclosed details enable various refinements and modifications according to antenna and system design considerations.
