| الملخص: | In this study, a linear connected printed inverted-F antenna (PIFA) array (LCPA) configured for a multiple-input multiple-output (MIMO) system is presented for use in 5G mm-wave applications. The design is compared with conventional antenna arrays to highlight the advantages of the proposed approach. Specifically, the proposed system consists of a four-element MIMO antenna array, where each element incorporates eight individual PIFAs, collectively forming a linear connected printed inverted-F antenna (LCPA) structure. To facilitate excitation of each LCPA, a tapered T-junction 1?×?8 power divider/combiner is employed. The LCPA is specifically designed to operate at a frequency of 28?GHz, suitable for high-frequency 5?G commu- nication. Experimental measurements show that the impedance matching bandwidth of the antenna spans 1?GHz, from 27.5 to 28.5?GHz, with a ?10?dB return loss, indicating effective resonance within this frequency range. The entire antenna array is fabricated on a substrate material, R0-4350B, with a total size of 130?mm by 68?mm and a thickness of 0.76?mm. This compact design, being single-layered and simple in its structural layout, makes it ideal for integration into mobile handheld devices, where space is a critical constraint. Overall, the proposed design offers a high-performance, efficient solution for MIMO antenna systems in 5G mobile communication applications. |
