Single and multiple input multiple output antenna wideband for 5G applications

Fifth-Generation (5G) mobile networks are the next major telecommunications standard that aims to address the increasing demands of mobile customers and the capacity limitations of existing 4G networks. antenna are established: double circuler antenna, MIMO double circuler antenna. The aim is to achieve broad bandwidth, good impedance matching, steady radiation patterns, high radiation efficiency, and compact designs for 5G applications. The research examines antenna performance metrics and guides 5G mm-wave antenna designers. The recommended antenna operates in the 28 GHz band and features a wide bandwidth of over 1 GHz, good impedance matching with lower reflection coefficient (S11≤ -10 dB), consistent radiation patterns, and high radiation efficiency to offset path loss. The optimized antenna geometry reduces the reflection coefficient and supports multi-polarization to prevent polarization mismatch losses. A Rogers-5880 substrate with a thickness of 0.78 mm.
