Abstract
This work proposes a multiband structure for cell devices, as well as a microstrip patch antenna array for 5G and 4G implementations. For a square-shaped slot, the multiband array structure is expected to function at resonant frequencies of 20.5 GHz, 25.5 GHz, 32.5 GHz, and 40.5 GHz. The intended antenna was constructed on a FR4 substrate with a dielectric constant of 2.4 and a thickness of 1.6 mm. An antenna array composite consists of a 4*2 component of the multiband construction for tapered line feeding. The array antenna's dimensions are 28.24mm*16.48 mm. The suggested antenna's length and breadth are computed to enhance the antenna array element's size. The antenna presented is appropriate for both 4G and 5G applications. In this article, several characteristics such as reflection coefficient, gain, and radiation pattern are examined.
