ABSTRACT = {This paper presents a compact Multiple Input Multiple Output
(MIMO) antenna with WLAN band notch for Ultra-Wideband (UWB)
applications. The antenna is designed on 0.8 mm thick low-cost FR-4 substrate
having a compact size of 22 mm × 30 mm. The proposed antenna comprises
of two monopole patches on the top layer of substrate while having a shared
ground on its bottom layer. The mutual coupling between adjacent patches
has been reduced by using a novel stub with shared ground structure. The stub
consists of complementary rectangular slots that disturb the surface current
direction and thus result in reducing mutual coupling between two ports. A
slot is etched in the radiating patch for WLAN band notch. The slot is used
to suppress frequencies ranging from 5.1 to 5.9 GHz. The results show that the
proposed antenna has a very good impedance bandwidth of |S11| < −10 dB
within the frequency band from 3.1–14 GHz. A low mutual coupling of less
than −23 dB is achieved within the entire UWB band. Furthermore, the
antenna has a peak gain of 5.8 dB, low ECC < 0.002 and high Diversity Gain
(DG > 9.98).},
