摘要
In this paper, a new EBG based compact design of dual band UWB MIMO antenna is proposed. This MIMO antenna operates in Ku-band and K-band. It consists of four slotted-rectangular element antennas and it occupies a compact size of 60.72×56.72 mm2. The existence of EBG enhances a -10 dB impedance bandwidth (VSWR ≤ 2) and it reduces mutual coupling. Based on the simulated numerical results, it is shown that the EBG based design has a 3.518 GHz of ultrawideband in Ku-band and a 3.699 GHz of ultrawideband in K-band, respectively. There is a 17.46 % bandwidth improvement in Ku-band. In addition, reducing the level of mutual coupling by using EBG technique reaches – 30 dB until – 70 dB along dual band. In addition, the presented design has very low ECC level, i.e., 0.003. This new proposed design has a good performance including low mutual coupling, compact size and ability to operate in dual band UWB.
