This work describes the construction of a microstrip line patch antenna having rectangular defective ground structure (DGS) to use in 5G mobile communications applications. This de-sign is used to operate at 3.3 GHz, 4.4 GHz, and 5.3 GHz, three different frequency bands. The antenna design, measuring 50.5 41.21 1.6 mm3, is positioned on a FR-4 substrate. It operates at impedance bandwidths of 10%, 14%, and 2.3%, with antenna gains of 6.01 dBi, 4.23 dBi, and 4.57 dBi at each of the three bands. The suggested antenna function within C band at frequencies of 0.582 Hz (5.033-5.615 GHz), 0.649 Hz (4.167-4.816 GHz), and 0.076 Hz (3.254-3.330 GHz), with radiation efficiencies of 85 %, 83 %, and 70 %. The findings demonstrate strong directivity, constant high gain, multi bands operating, and advantageous directional radiated patterns. The antenna's omnidirectional transmission pattern, significant gain, and effective radiation make it a feasible choice for the spectrum of 5G communication systems in a number of situations. For 5G portable devices, this suggested antenna may be helpful. The need for active beam forming antenna configurations within 5G mobile communications, particularly across the below-6 GHz wavelength band, necessitates the integration of novel electronics with antennas. |
