Antenna arrays that incorporate MIMO technology for indoor–outdoor network interconnection on the same terminal, i.e., for DCS 1800, PCS 1900, WCDMA, 3G, 802.11a/b/g, Bluetooth®, ZigBee®, WiMAX™, and UWB standards, are proposed. Staircase profile printed circuit antennas, monopoles (PCM), and slots (PCS) with VSWR < 2 bandwidth mainly from 1.12 to 10.1 GHz are previously designed, simulated, constructed, and measured as antenna elements for those arrays. For comparison, prototypes for two‐element PCM and PCS MIMO arrays have been constructed and measured. The choice should be made according to the directivity required by the final application and portable device size. For the worst signal interference case, the operational bandwidth ranges from 1.5 to 9.9 GHz and from 1.7 to 11.4 GHz for the PCM and the PCS MIMO arrays, respectively. VSWR is basically below two, average capacity loss 0.32 bps/Hz with respect to the ideal uncorrelated (2,2) case and envelope correlation lower than 20 dB. © 2010 Wiley Periodicals, Inc.
