Design of A Small UWB Antenna with Double Band-Notched Characteristics with Low Correlation for MIMO Applications

A small low correlation multiple-input multiple-output (MIMO) antenna with double band-notched characteristics for UWB requests with a small size of 22 × 42 mm2 is offered. The MIMO antenna comprises two identical elements each of that has a stepped patch with U-shaped slot, two rectangular shaped slots in the ground plane and a butterfly shape element on back of construction. The antenna elements are placed orthogonally to attain an acceptable isolation with a low ECC between the two input ports. The measured frequency results show an impedance bandwidth of 11.02 GHz over 1.98–13.0 GHz for l0 dB return loss with two rejected bands centered at 3.39 (940 MHz) and 5.36 GHz (1370 MHz) to limited the WLAN and WiMAX bands, along with a primary portion of the C band. The results demonstrate that the antenna can be evaluated as a fine choice for UWB MIMO systems.
