This paper presents the design and realization of a 2×1 rectangular microstrip array antenna operating at 3.5 GHz for 5G communication systems. The design incorporates inset feed and U-slot techniques to improve antenna performance in terms of return loss, gain, and bandwidth. AWR Microwave Office 2009 was used for simulation, and iterative optimization was conducted on parameters such as feed position and slot dimensions. The final prototype achieves a return loss of –36.75 dB, a gain of 9.246 dB, a VSWR of 1.115, and a bandwidth of 169 MHz. These results demonstrate the effectiveness of combining array configuration, inset feed, and U-slot techniques for enhanced antenna characteristics.
