In this manuscript a defective ground structure based dual port MIMO antenna configuration for future generation communication networks is designed and presented. The MIMO antenna measures 120 × 60 × 0.8 mm3 in size and is designed using Rogers RT5880 substrate material. The single port antenna is designed and optimized at first. After that, a two-port structure is designed and optimized. The proposed antenna covers frequency from 1.9 GHz to 2.45 GHz. To produce proper resonance, a defective ground structure is introduced into the ground plane. This antenna is self-decoupling, with an isolation of −15 dB between its elements. All MIMO diversity parameters and radiation properties are assessed, in addition to the mutual coupling. The proposed MIMO antenna configuration designed and optimized to offer TARC <− 10 dB, MEG −3 dB, DG ~9.99 dB, ECC <0.02, and gain 3.25 dBi. All assessed MIMO diversity features work reasonably well. The proposed two port MIMO antenna can be used for WLAN and 5G applications.

摘要

In this manuscript a defective ground structure based dual port MIMO antenna configuration for future generation communication networks is designed and presented. The MIMO antenna measures 120 × 60 × 0.8 mm3 in size and is designed using Rogers RT5880 substrate material. The single port antenna is designed and optimized at first. After that, a two-port structure is designed and optimized. The proposed antenna covers frequency from 1.9 GHz to 2.45 GHz. To produce proper resonance, a defective ground structure is introduced into the ground plane. This antenna is self-decoupling, with an isolation of −15 dB between its elements. All MIMO diversity parameters and radiation properties are assessed, in addition to the mutual coupling. The proposed MIMO antenna configuration designed and optimized to offer TARC <− 10 dB, MEG −3 dB, DG ~9.99 dB, ECC <0.02, and gain 3.25 dBi. All assessed MIMO diversity features work reasonably well. The proposed two port MIMO antenna can be used for WLAN and 5G applications.
