The four-port MIMO antenna facilitates the use of the characteristics of the C-, X-, and Ku-bands. The four radiating patch elements have been mounted on top of a 20 mm × 20 mm × 1.6 mm FR-4 substrate with a dielectric strength of 4.4. The suggested MIMO antenna functions with isolation between radiating elements exceeding 20 dB at an effective frequency of 7.5 GHz. To enhance the separation of antenna elements, orthogonal placement has been adopted. The suggested MIMO antenna was simulated using the HFSS software. The simulated values of ECC, CCL, and DG are less than 0.5, 0.4 bps/Hz, and near 10 dB, respectively. The multiband responses make the proposed work satisfactory for C-band (4.34 GHz and 6.50 GHz), X-band (9.72 GHz), and Ku-band (13.98 GHz) applications in wireless communication such as satellite, TV, and RADAR applications.

摘要

The four-port MIMO antenna facilitates the use of the characteristics of the C-, X-, and Ku-bands. The four radiating patch elements have been mounted on top of a 20 mm × 20 mm × 1.6 mm FR-4 substrate with a dielectric strength of 4.4. The suggested MIMO antenna functions with isolation between radiating elements exceeding 20 dB at an effective frequency of 7.5 GHz. To enhance the separation of antenna elements, orthogonal placement has been adopted. The suggested MIMO antenna was simulated using the HFSS software. The simulated values of ECC, CCL, and DG are less than 0.5, 0.4 bps/Hz, and near 10 dB, respectively. The multiband responses make the proposed work satisfactory for C-band (4.34 GHz and 6.50 GHz), X-band (9.72 GHz), and Ku-band (13.98 GHz) applications in wireless communication such as satellite, TV, and RADAR applications.
