Super Wide Band Mickey Shaped Mimo Antenna for Wireless Communication

In this communication, a 4 element MIMO antenna is designed for Super-Wide-Band (SWB) wireless applications. The antenna structure is comprised using four mickey-mouse shaped radiating elements. Antenna with the overall size of 60×60×1.670mm³ is implemented on the FR4 substrate using CST-Microwave lab Tool. The proposed MIMO antenna is operated with in super wide-band (SWB) frequency range (4-25GHz) with peak gain of 8.55 dB. The extended bandwidth up to such extent is accomplished by etching circular ground structures within ground plane. Isolation up to 20 dB, among the radiating elements is attained by their orthogonal placement on the substrate. Operating bandwidth, efficiency and gain of the designed antenna is compared with the prevailing literature. ECC value for the designed structure is less than 0.008 and other satisfactory performance criteria are to be considered. The presented antenna could be a good contender for several applications such as: Military mobile devices, WIMAX, C, X, Ku, and K Band.
