Mimo antenna with decoupling circuitry

A multiple-input and multiple-output (MIMO) antenna for use in a distributed antenna system, the MIMO antenna comprising:

• (a) a feeding circuit disposed on a dielectric substrate, the feeding circuit comprising a coplanar waveguide (CPW) comprising a signal feed and a return, the return comprising first and second return sections coplanar with and apart from the signal feed;
• (b) first and second radiator circuits disposed on the dielectric substrate, the first and second radiator circuits comprising first and second monopole radiators, respectively, the first and second return sections being coplanar with and spaced apart from the first monopole radiator;
• (c) a decoupling circuit disposed on a first side of the dielectric substrate, the decoupling circuit comprising a conductive strip for reducing mutual coupling between the first and second radiator circuits;
• and
• (d) a matching circuit comprising a plurality of stubs disposed on a second side of the dielectric substrate opposite the first side, the matching circuit being operable to reduce return loss of the MIMO antenna.
