Innovation Design of High Gain Array Antenna for 5G Communication

The fifth-generation (5G) wireless communication system requires high gain antennas to support the growing demand for high-speed data transmission and low-latency connectivity. High gain antennas are crucial for enhancing the signal strength and extending the coverage area of 5G networks. By using multiple antenna elements, an array can achieve higher gain and directivity compared to a single element antenna. This improvement in gain enables better signal reception and transmission, leading to increased communication range, higher data rates, and improved reliability. In this paper, we discuss the design and implementation of antenna arrays for improving antenna gain in 5G communication systems at 3.5 GHz.The design of the array antenna incorporates single, dual, quad, and octal element structures to enhance the antenna's gain. The proposed antenna has been examined, and the results indicate that it has a return loss of -37.4 dB at the resonant frequency of 3.5 GHz, an antenna gain of 7.22 dB, and a bandwidth of 286.5 MHz. The use of a single, dual, quad, and octal element array configuration is anticipated to improve the gain performance of the antenna, making it a promising option for 5G communication systems.
