UWB MM-Wave antenna array with quasi omnidirectional beams for 5G handheld devices

An ultra-wideband (UWB) millimeter-wave (mm-Wave) dipole antenna array for fifth generation (5G) communications is presented in this paper. The proposed antenna is working in the frequency range of 23-33 GHz (10 GHz bandwidth with more than 35% FBW). Ten compact UWB dipole antenna elements designed on a Rogers RT5880 substrate have been deployed along the edge region of the cell phone PCB. The feature of compact design with UWB characteristic makes them well-suited for 5G cellular devices such as laptops, tablets, mobile phones etc. Input impedance and radiation properties of the proposed antenna array have been discussed. The antenna features quasi-omnidirectional radiation beams at different scanning angles.
