Abstract

A low-profile electronically reconfigurable WiMAX band-notched dual port multiple-input multipleoutput (MIMO) antenna design for ultra-wideband application has been presented. The two symmetrical MIMO antenna elements proposed in this work exhibit a good impedance match (VSWR ≤ 2) over frequency band of 3 to 12 GHz, while offering high isolation. The decoupling structure is used to enhance the isolation level above 25 dB over the entire UWB spectrum. The reconfigurable band notch characteristic in MIMO design is achieved by inserting PIN diodes along the filtering Ω-shaped slotted structure in main radiators. Notch appears for WiMAX 3.5 GHz (3.2-3.8 GHz) frequency band by switching the PIN diode to 'ON' state. The proposed antenna is fabricated and measured, the results suggest its appropriateness for UWB applications where WiMAX band notch characteristics may be desired on-demand.
