摘要

The demand of high-speed data rate transfer, streaming and the expansion of the infrastructure of the Ultra-Wide Band communication in means of wireless communication has become a vital consideration in improving the Gigabits bitrate. The usage of MIMO antenna in many wireless applications acts as both the source of transmitter and receiver. These antennas are advantageous in working with higher rate of data, diverse time and with diverse frequency range. The proposed study utilize the two-element flower shaped Ultra-Wide Band Multiple Input Multiple Output (MIMO) antenna with a dual notching of range 5.6 GHz and 7.2 GHz which comprises good isolation rate.The antenna uses a dodecagon shaped Complementary Split Ring Resonator (CSRR) for the realization of notching with range of 7.2 GHz. A novel decoupled structure is used for enhancing the rate of isolation loss. The substrate RT Duroid 5880 is used with a dielectric constant at a range of 2.2 and a height (length) of 0.79. The complete size of the antenna ranges from 30.5 × 42.2 × 0.79 mm3. The S11 is obtained less than − 10 dB by using the antenna. The range of VSWR is less than 2. The isolation loss is at a considerable range constituting the entire band. The complete bandwidth of the proposed antenna is in a measurable range. The antenna's performance is evaluated based on parameters such as Total Active Reflection Coefficient, Channel Capacity Loss, Diversity Gain, Mean Effective Gain, and Envelope Correlation Coefficient.
