A two-element Ultrawide band (UWB) circular Microstrip patch Multiple Input Multiple Output (MIMO) antenna is proposed in the presented work for 5G, WLAN and satellite applications. The UWB is developed on design space 35 × 39 × 1.6 mm3 with edge to edge spacing of 3 mm which is a key feature of the design regarding compaction and miniaturization. A single resistance loaded parasitic element is introduced between the MIMO elements in the same plane to enhance isolation without utilization of extra space. This decoupling structure is added with the reduced ground with rectangular cut without affecting the gain of the structure. The working frequency range of the UWB achieved for this design is from 3.5 GHz to 8.2 GHz with isolation more than 20 dB and gain from 2 to 5 dBi. The surface current distribution along with diversity parameters such as Envelop correlation coefficient (ECC) and diversity gain (DG) further confirms the improved characteristics of the proposed UWB in a compact design space for 5G, WLAN and satellite applications.

摘要

A two-element Ultrawide band (UWB) circular Microstrip patch Multiple Input Multiple Output (MIMO) antenna is proposed in the presented work for 5G, WLAN and satellite applications. The UWB is developed on design space 35 × 39 × 1.6 mm3 with edge to edge spacing of 3 mm which is a key feature of the design regarding compaction and miniaturization. A single resistance loaded parasitic element is introduced between the MIMO elements in the same plane to enhance isolation without utilization of extra space. This decoupling structure is added with the reduced ground with rectangular cut without affecting the gain of the structure. The working frequency range of the UWB achieved for this design is from 3.5 GHz to 8.2 GHz with isolation more than 20 dB and gain from 2 to 5 dBi. The surface current distribution along with diversity parameters such as Envelop correlation coefficient (ECC) and diversity gain (DG) further confirms the improved characteristics of the proposed UWB in a compact design space for 5G, WLAN and satellite applications.
