Design and Analysis of a Linear 4-Patch Antenna System for 5/6G Technology

In 5/6G technology, antennas and antenna systems play a key role in ensuring high-speed, low-latency, and high-reliability wireless communication. Due to their compact size, high gain, and easy integration, patch antenna arrays are frequently used in the sub-6 GHz and mmWave (millimeter-wave) bands, supporting applications such as IoT, smart cities, and autonomous vehicles. Developing efficient and adaptable antenna systems is essential to meet the ever-increasing demands of 5/6G networks. This article aims to create a linear 4-patch antenna system that can be easily used and integrated into mobile communications, satellites, or drones applications that can be used in different IoT, environmental monitoring and precision agriculture. The system performance will be studied by analyzing various parameters such as reflection coefficient, gain VSWR (Voltage Standing Wave Ratio). This work seeks to obtain the best possible gain value of the linear system in the 5/6G high-frequency spectrum.
