| Abstract | ||
| A two-element antenna system is designed and fabricated with good isolation in this manuscript. The offered antenna gets two resonance frequencies at 28 GHz and 38 GHz which are allotted for the upcoming 5G mobile applications. The offered antenna is designed and simulated using industrystandard software CST MWS program. The basic antenna design is conventional microstrip antennas placed at the lower edge of the mobile substrate. The obtained reflection coefficient is -27.908 dB from (26.961 - 29.266) GHz with impedance bandwidth 8.19 % and -20.58 dB from (36.646 – 40.297) GHz with impedance bandwidth 6.09%. The mutual coupling between two antenna ports is less than -30 dB. The achieved directivity, far-field gain, and efficiency are 7.581 dBi, 7.182 dBi and 91.24 % at 28 GHz and 9.716 dBi, 9.24 dBi and 89.63 % at 38 GHz, respectively. The size of the Rogers 5880 substrate is 55 x 115 mm2 with h = 0.508 mm and ℇr =2.2 which is low cost substrate and small size patches best suited for miniaturized devices. | ||
