Differential Fed Bilateral Slotline Dipole on Flexible PCB for mm-Wave 5G Mobile Terminal

This paper proposed a low-profile flexible antenna for mm-wave 5G mobile terminals at 28 GHz. The proposed antenna structure is fed through a differential stripline. It consists of a bilateral slotline and a bilateral dipole symmetrically arranged on the top and bottom ground planes. Since the proposed structure is flexible, it can be inserted into the package of the terminal in a curved shape. Simulation results show that the proposed antenna has good performance suitable for 5G mobile terminals.
