초록
A low-profile, ultra-wideband (UWB), multi-input multi-output (MIMO) antenna for a personal digital assistant application is proposed. To improve the impedance bandwidth, a 2 mm x 1 mm connecting strip is used on each antenna element. The isolation characteristic between the two antenna elements is improved by inserting two T-shaped stubs. The optimized design parameters were obtained through parametric analysis. The designed antenna has a 10-dB return loss bandwidth of 9 GHz (2.2-11.2 GHz) covering the WiBro, Bluetooth, WiMax, S-DMB, and UWB frequency bands, with an isolation characteristic below -20 dB over the operating frequency. Additionally, the envelope correlation coefficient is less than 0.12.
