Abstract
A novel, miniature multiple input multiple output (MIMO) ultra wide band (UWB) antenna with dual notched characteristics is proposed. The antenna incorporates a tapered microstrip feed line with two radiating patch structures procured by the incorporation of two ellipses with a circle and a reduced ground structure. The proposed antenna is printed on an FR-4 substrate having a concise size of 40 x 22 mm2 to cover -10 dB bandwidth of 3.18-11.26 GHz with fractional bandwidth of 112%. The two notched bands 3.31-3.99 GHz for WiMAX and 4.97-5.93 GHz for WLAN accomplished by two T-shaped parasitic structures are etched above ground plane and inverted U- shaped slots etched on radiating patch, respectively. The isolation of < -15 dB is realized by inserting a T-shaped stub in between two patch elements. The measured MIMO diversity characteristics are the evidence of that the proposed antenna is appropriate for portable wireless applications.
