Abstract- The mutual coupling between closely-spaced patches, we propose a two-step decoupling design approach for a micro strip antenna array with the dimensions of 44.9 × 30.495mm2. first step is designing a decoupling unit on the basis of wave guided complementary split-ring resonators (WCSRRs) to improve isolation. The second step is presenting an optimization method by using a fully connected neural network (FCNN) to enhance design efficiency. By inserting WCSRRs structure between two patches with the edge-to-edge distance of 0.24*0 (port-to-port distance with 0.66*0), measured isolation of the predicted micro strip antenna array is increased to 41.05 dB and 52.33 dB, respectively. All the simulated and predicted results are validated via the measurement to demonstrate the effectiveness of our design scheme.
