Millimeter-Wave Dual-Band Slotted Antenna for 5G Applications

Abstract

This paper presents a millimeter-wave dual-band slotted antenna (26.28/37.72 GHz) for fifth-generation (5G) network. The dielectric layer of the antenna is made of Rogers RT 5880 material and has a thickness of 0.254 mm. The resonant frequencies of 26.28 GHz and 37.72 GHz, among the most desirable frequency bands for 5G communication in the mobile network, are used in this study. The designed dual-band slotted antenna has an architectural structure of 8 mm × 6mm × 0.254 mm. It achieves a gain of 5.464 dB and 6.705 dB and directivity of 6.18 dBi and 7.538 dBi with the assistance of the Reflection Co-efficient at resonant frequencies of –21.79 dB and –34.55 dB. With bandwidths of 0.867 GHz and 1.054 GHz, the proposed antenna’s efficiency was successfully attained 84.81% and 82.55%, respectively, which is suitable and enough efficient for 5G communication. The Microwave CST Studio Suite tool is used to design and simulate this proposed antenna. According to the intended results, the suggested antenna works excellently, and due to its fundamental architecture, the proposed antenna will be suitable for mobile networks. The designed antenna can be appropriate for faster mobile networks and 5G communication technologies by estimating all the parameters.
