Design of a flexible MIMO antenna with return loss compensation

This article suggests a method for the return loss compensation for flexible antennas. MIMO-antenna with nine patches and its model were designed with operating frequency of 5.33 GHz. The antenna was measured and simulated in different states, and for compensating the return loss increase during bent state of antenna the all-capacitance matching network was suggested with variable values. Compensation method of using the matching network with reactive components allows decreasing the difference in parameters in bent state comparing with flat state of antenna by 80%.
