Abstract
A reconfigurable dual-port diversity antenna for ultra-wideband application is presented. The proposed design can be configured either in stacked/back-to-back arrangement by placing radiating elements facing in the opposite directions or in orthogonal arrangement. The proposed designs are realised on FR4 substrate of dimensions 40 × 36 × 1.5 mm. By introducing an efficient decoupling structure in the ground plane, both configurations maintain an isolation better than 25 dB over the complete band. Performance of the proposed design is verified by the measured results including s-parameters, envelope correlation coefficient, total active reflection coefficient and channel capacity loss. The proposed design is suitable for integration in three-dimensional (3D) system-in-package applications.
