This paper presents a compact dual-band-notched super wide band (SWB) multiple-input multiple-output (MIMO) antenna for UWB applications. The bandwidth of the antenna is near 38 GHz from 2.3 to 40 GHz, which covers L, S, C, X, Ku, K, and Ka bands and has two notched frequencies around 3.1-3.7 GHz for WiMAX and 5.1-5.8 GHz for WLAN. This antenna comprises two identical elements, fed by two 50 Ω microstrip lines and placed adjacent on a low-cost FR-4 substrate. The total size of the antenna is about 31 × 65 × 1.6 mm3. To suppress the interferences of WiMAX and WLAN bands, two elliptic single complementary split-ring resonators (ESCSRRs) were etched out of the radiating patch and to achieve a good isolation between the two elements a long vertical open-ended slot is etched out of the shared ground plane and an isolation of more than 17 dB is achieved. In addition, the Envelope Correlation Coefficient (ECC) value is less than 0.01.
