Design of Multi-band Microstrip Patch Antennas for Mid-band 5G Wireless Communication

Abstract

Recently, the best antenna structures have considered microstrip patch antenna due to their simple construction, low cost, minimum weight, and the fact that they can be effortlessly integrated with circuits. To achieve multiband operation an antenna is designed with an etching rectangle and circle slot on the surface of the patch to achieve multi-band frequency capabilities in mid-band 5G applications. Inset-fed structure type of fed of all antenna printed and fabricated on the brow of the Rogers RT5880 substrate. Then, prototype structures of the microstrip patch antenna were acquired during the design process until achieving the desired antennas. The antenna_1 achieved tri-band characteristics covering the WiMAX band including 2.51 -2.55 GHz, WLAN, and S-band including 3.80 -3.87 GHz and C-and X-band including 6.19 -6.60 GHz. The antenna_2 gives dual-band characteristics covering C-band and X-band including (6.72 -7.92 GHz) with a peak under -45 dB suitable for mid-band 5G applications. High impedance bandwidth increases between (70 MHz-1.25 GHz) for wireless applications. The proposed microstrip patch antennas were simulated using CST MWS-2015 and were experimentally tested to verify the fundamental characteristics of the proposed design, it offers multiple-band operation with high stable gain and good directional radiation characteristics results.

Design and Optimization of Microstrip Patch Antennas for Wireless Communication Systems– A Literature Review

“…Renowned for their uncomplicated assembly, cost-effectiveness, and seamless integration with circuits [5], these antennas can be tailored to attain multi-band frequency capabilities through the incorporation of etched rectangle and circular slots on the patch surface [13]. Moreover, augmenting the bandwidth and gain of microstrip patch antennas can be achieved by introducing slots on the antenna, thereby enhancing key parameters such as bandwidth, gain, and directivity [14]. Additionally, inventive designs integrating magnetic materials within the dielectric substrate have been proposed to diminish the antennaʹs resonant frequency and profile, potentially amplifying gain with forthcoming advancements in magnetic materials [15].…”

“…Additionally, a new antenna construction with slots and shorting elements is introduced to achieve multi-band performance. It identifies many challenges and constraints, including the difficulty in getting accurate shorts during the manufacturing process, the complexity of creating a new planar antenna construction that can operate in several frequency bands, and the requirement to guarantee that the experimental and simulation results are consistent [14].…”
