Abstract
In the present article, a fork-shaped UWB-MIMO antenna is designed and experimentally tested to achieve hexa-band rejection characteristics. Initially, the proposed array consists of two fork-shaped radiators and a reduced ground with a vertical stub, designed to cover a large bandwidth from 3.64–12.2 GHz and high port-to-port isolation. Furthermore, each fork-shaped radiator is defected with two U-shaped slots, inverted U-shaped slot, complementary SRR and a pair of Z-shaped slots to eliminate the interfering frequency bands at 3.95 GHz (downlink C-band), 4.8 GHz (INSAT), 5.35 GHz (WLAN), 6.19 GHz (uplink C-band) and 8.4 GHz (ITU-8) respectively. The reduced ground is loaded with two G-shaped slots to suppress the interfering amateur radio band (10.01–11.27 GHz). The total volume occupied by the proposed array is 21.5 × 57 × 1.64 mm3. The diversity performance of the proposed array is characterized by low ECC, high DG, high MEG, low CCL and stable TARC characteristics. A close resemblance is achieved between the simulated and experimental results.
