A single rectangular microstrip antenna is developed for wireless applications, along with a 2×2 Multiple Input Multiple Output (MIMO) antenna array. The substrate is formed out of polyimide material, having an electrical dielectric constant of 3.5 and a thickness of 0.04 mm. An extremely small rectangular patch antenna with measurements of 0.075 mm by 0.11 mm by 0.04 mm is employed in the proposed MIMO antenna array. For the resonating frequency, performance metrics such as reflection coefficient, efficiency, bandwidth, peak gain, antenna directivity, and VSWR are computed. The intended MIMO array has a reflection coefficient of less than -10 dB and resonates for two different frequencies: 0.7638 THz, and 1.0804 THz. The developed MIMO array has a maximum possible antenna gain and directivity of 12.30 dB and 12.33 dB respectively, maximum radiation efficiency of 90% and VSWR below 2 for the resonant frequency. Moreover, the MIMO parameters for also observed, such as ECC being 0.0008, diversity gain being 9.9999 dB, CCL being 0.44 and 0.42, MEG being -2 to 0 dB and TARC being below -20 dB.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
