Abstract
A multiple-input-multiple-output (MIMO) antenna-deploying fractal structure is presented for
ultra-wide band (UWB) applications. Furthermore, one band notch (WLAN) is introduced on the
radiating patch with a PIN diode to achieve reconfigurability. The antenna consists of two planar
fractal elements on one side of the substrate along with the microstrip-fed line. The grounds of these
elements are connected via a tiny strip on the other side to form a single ground. To reconfigure
the notch, the PIN diode acts as a switch. When the diode is turned off, the antenna's impedance
bandwidth exceeds 3.1-10.6 GHz, and the WLAN spectrum (5.15-5.725 GHz) is notched. The
performance of the antenna is investigated by examining the reflection coefficients of the two ports.
There are further measurements of antenna gain, VSWR, envelope correlation coefficients (ECC),
and diversity gain (DG).
