In this paper, a novel dual-band Y-shaped monopole patch antenna is proposed, designed, and fabricated for a 5G wireless application. The radiator patch of the antenna's wide and length was fabricated on an FR-4 substrate with the dimension of the proposed antenna of 27.88×23.67×1.58 mm3. The CST studio suite is utilized for all the virtual simulations and analyses regarding fabricated antennas. The study reveals that the fabricated antenna has a bandwidth of 6.20 GHz, covering 3.20-4.60 GHz and 5.10-9.90 GHz frequency ranges, respectively. The antenna has a nice S11 characteristic, excellent impedance matching, and an almost omnidirectional radiation pattern. The S11 is observed at -23.30 dB, and -26.60 dB for the resonate frequency of 3.75 GHz and 7.10 GHz, correspondingly, which covers two Malaysian 5G, frequency bands. The peak gain is 4.78 dB, and the maximum efficiency is 92%, accordingly to the whole frequency band. The VSWR is ideal at 1.02. Finally, the proposed antenna is an attractive solution for 5G wireless communication..
