Methods and systems for implementing and operating multiple-input and multiple-output (MIMO) antennas for radio telecommunications
Methods and systems for implementing and operating antennas, particularly multiple-input and multiple-output (MIMO) antennas. An example antenna may include a planar dielectric substrate, a primary conductive area on a first surface of the planar dielectric substrate, a first secondary conductive area on the first surface, a second secondary conductive area provided on the first surface, and one or more signal connections for connecting to one or both of the first secondary conductive area and the second secondary conductive area. The primary conductive area may have a shape defining at least a first region of the first surface bounded by at least a portion of the primary conductive area. The first secondary conductive area may be in the first region of the first surface.
