Abstract : In this paper, 1 × 1 and 2 × 2 Multiple-input Multiple-output (MIMO) antenna is designed for a multiband application. The antenna consists of three concentrated decagon shaped rings which are responsible for obtaining the three resonance frequencies. The proposed antenna has a unique design technique; without using any decoupling structure the antenna attains better isolation performance. First, a two (1 × 1) element MIMO antenna with three different orientations (Orientation-I, II, and III) is studied. Second, a four-element MIMO antenna is designed without any decoupling structure for better performance. The above two antenna designs are fabricated and measured. The dimension of the proposedantenna element is 23.5 mm × 26.5 mm, and it has -10 dB impedance bandwidth over 2.4-2.52 GHz, 3.66-4 GHz, and 4.62-5.54 GHz, which cover various applications such as WLAN (2.4/5.2 GHz), WiMAX (2.5/5.5 GHz), public safety (4.9 GHz), and 5G (3.6-3.8 GHz). The proposed MIMO antenna diversity performances such as isolation, ECC, Directivity Gain, TARC, Channel Capacity Loss (CCL), and Mean Effective Gain (MEG) are studied.
