A Compact Fractal Shaped 8-Elements Antenna Array for 5G mm-Wave Communication

This paper proposes a compact antenna design for wireless communication. The antenna is compatible for millimeter-wave (mm-wave) of 5th generation (5G) band. The design consists of a modified circular shaped patch on a Rogers RT/Droid 5880 substrate having relative permittivity εγ = 2.2 and dielectric loss tangent of σ= 0.0009 with overall dimensions of 4x4x0.152 mm3 with partial ground plane. The proposed antenna is further extended into 8 elements multiple input multiple output (MIMO) antenna array and a chain shaped strip is used to achieve isolation and to match impedance between the antennas. Additionally, the proposed design offers a wide bandwidth of 16.5 GHz from 17.8 GHz to 33.6 GHz.
