Modified Circular Common Element 4 Port MIMO Antenna Using Diagonal Parasitic Element

Abstract: 

A 4-port multiple input multiple-output (MIMO) antenna with common radiating element is proposed for 2.4 GHz Wi-Fi applications. It comprises a modified circular radiator fed by four identical modified feedlines, partial ground planes and a diagonal parasitic element. The parasitic element is used to enhance the inter-port isolation. The antenna has an experimental impedance bandwidth of 220 MHz (2.34-2.56 GHz) and nearly omnidirectional radiation patterns. The radiation efficiency is more than 80% and gain is 2 dBi at the frequency of 2.43 GHz. The isolation in the given frequency band is -10 dB. At the resonance frequency i.e. 2.43 GHz, the isolation between adjacent ports (1, 2 and 1, 4) is 14 dB and between opposite ports (1, 3) is 12 dB.  The mean effective gain (MEG) ≤-2.7 dB and envelope correlation coefficient (ECC) less than 0.01 are achieved. The diversity gain is about 10 dB between adjacent ports i.e. 1 and 2.
