This paper proposes a simple multiple input multiple output (MIMO) microstrip patch antenna for superwideband applications. The antenna has percentage bandwidth of 182.17% for superwideband (14–300)GHz and also supports two significant frequency bands having bandwidth of 2.35GHz (0.1–2.45GHz) and 2.1GHz (7.2–9.3GHz). For all frequencies the antenna input impedance is matched with 50 Ω coplanar waveguide feeding. The antenna is simulated using CST Microwave Studio software. −30dB isolation between MIMO ports and the envelope correlation coefficient value is below 0.1 makes the antenna an ideal candidate of MIMO superwideband antenna. Furthermore 53dB front to back ratio and 33dB directivity with more than 88% radiation efficiency is found in simulation result. Integration of this antenna with microwave integrated circuits is also possible. Design details and results are presented.
