The Novel Monopole Antenna for Sub-6 GHz 5G Applications

This paper explains the novel monopole antenna's design and analysis for the sub-6 GHz 5G applications. The proposed antenna has a volume of 20 x 20 x 1.6 mm3. In the antenna design, the most commonly used classical insulating material, FR4, with a thickness of 1.6 mm, is used, and it is obtained from the reversed-cross-shaped radiator and modified with the help of the stubs and slots to resonate in the 3.4-3.8 GHz band. The antenna has a highest gain of 2.2 dBi and an efficiency of 98%. The suggested antenna can be utilized for 5G applications at frequencies below 6 GHz.
