A Super-Wideband Multiband MIMO Antenna for Microwave and Millimeter Wave Wireless Applications

This communication reports a multi-super-wideband microwave-access antenna that achieves a bandwidth of 8.56GHz-39.02GHz and finds applications for X-band, Ku-band in Microwave and 28.0GHz & 38.0GHz for millimeter-Wave band 5G infrastructure. The patch which radiates electromagnetic energy consists of a hexagon shape with partial rectangular ground printed on Rogers-Substrate with a thin thickness of 0.254mm. The proposed work with a single element occupies a very compact space of 120 mm(2) and the MIMOSWB counterpart occupies a space of 240 mm2. The proposed antenna releasing EM wave offers an average peak realized gain of 4.74dBi and directivity of 4.09dB. The proposed antenna also offers desirable 2-D radiation patterns at 10.60GHz, 16.0GHz, 28.0GHz, and 38.0GHz respectively. The MIMOSWB configuration with an edge-to-edge spacing of 2.50mm achieves isolation of more than 12.50dB with diversity parameters ECCSWB<0.12, DG(SWB)>9.995dB, TARC(SWB)<-27.50dB and CCLSWB<0.30b/s/Hz. The antenna radiating technology achieving several useable bands is useful in mobile networks for achieving information and communication system.
