DESIGNING OF ANTENNAS FOR 5G NETWORK APPLICATIONS

Microstrip patch antennas have been designed and demonstrated for 5G network applications. Patch antennas with square, circular and hexagonal geometries are simulated for V-band frequencies using Computer Simulation technology (CST). The radiating patch and ground plane are made of copper. The dielectric substrates for patch of antennas are RT 6002, RT 5880 and FR-4 having relative permittivity values of 2.94, 2.4, and 4.3, respectively. Square, circular, and hexagon patch antennas return loss, VSWR, bandwidth, and efficiency are - 50.43 dB, 1.006, 11.347 GHz, and 95.9%; for circular patch antennas, they are - 14.5 dB, 1.464, 5.67 GHz, and 93.7%; and for hexagon patch antennas, they are -15.9 dB, 1.38, 4.57 GHz, and 87.26%. The outcomes of research suggest that the square-shaped patch antenna is a successful prototype for fifth-generation wireless communication systems. Two methods are used to calculate the bandwidth of a patch antenna: the percentage approach and the frequency difference method. The main focus is on the frequency difference; the antenna bandwidth is calculated by subtracting the higher frequency signal from the lower frequency signal. The required bandwidth provided by a square patch antenna would be a more efficient prototype for wireless communication systems. Keywords: Antenna, Bandwidth, CST, VSWR, time series.
