Design and Analysis of Flexible 2-Port MIMO Antenna with Reflector Ground for WLAN Applications

A two-port flexible MIMO antenna system suitable for WLAN networks is proposed to resonate at a resonating frequency of 2.4 GHz. The proposed antenna response over the plane is analyzed based on the gain, reflection coefficient, diversity gain, isolation parameter, and radiation pattern. The two MIMO elements are patterned in cylindrical shape over the flexible Kapton substrate. The choice of Kapton material as the substrate allows the design to have the greatest amount of physical flexibility. The typical antenna parameters for the suggested design were examined with an increased gain of 4.8 dB and the reflection coefficient S11 to be −45 dB. The proposed design using the reflector ground structure in the antenna was also observed for the radiation pattern, diversity gain, and ECC (Envelope Correlation Coefficient.
