Abstract

In this article compact multiple input multiple output (MIMO) antenna with triple notch at the ultra-wideband application having two identical monopole antennas is proposed. The two inverted ‘U’ shaped slots are etched on the antenna geometry. The proposed antenna gets notch obtain notch characteristics at three frequencies i.e. 3.51–4.3 (WiMAX), 5.5–5.6 (WLAN) and 8.4–8.8 (X-band applications in UWB spectrum the proposed antenna is designed on FR4 substrate with a compact size of 20 × 34 × 1.6 mm3. The proposed antenna was designed and analysed HFSS 13. An excellent triple notch characteristic is obtained after insertion of Inverted ‘U-shaped compact slot on the radiators. At the centre of the triple notch bands a significant drop in the gain, efficiency of the antenna is seen this indicates a good suppression in the interference of two elements. The simulated and measured results show that the proposed is used for UWB MIMO diversity systems. Thus the proposed antenna two elements are used reduce isolation between channels for ultra wideband MIMO diversity systems.
