| Popis: | A novel compact planar 2 × 2 antenna system with super-wide bandwidth is presented in this paper. The MIMO antenna has four square-shaped patches with two slots in each that are interconnected with each other using four strip lines printed on a substrate of Rogers Duroid RT 5880 with relative permittivity of εr = 2.2 and tangent loss of δ = 0.0009. The proposed antenna system has a partial ground plane with two enhancement fractured slots. The design is characterized by a super-wide impedance starting from 15.2 to 62 GHz (a bandwidth of 46.8 GHz) and compact total system size of 11.2 × 15.25 mm2 with a thickness of 0.12 mm. The proposed MIMO design has omnidirectional radiation pattern for far field and the achieved peak gain reaches 13.5 dBi. The presented planar antenna which relies on computer aided design, has been designed and simulated using an industrial standard simulation code. Its performance results showed that the MIMO design is characterized by super wide bandwidth, omnidirectional radiation pattern, and high-power gain with miniaturized physical size thus, it is suitable for radio-frequency identification (RFID) systems, fifth-generation applications, ultra-wideband systems, and others. |
