5G Communications Multiband Antenna Design

Abstract

In this paper, a novel reconfigurable antenna with multiband of frequency is analysed and simulated for the modern 5G mobile communication applications. The proposed antenna is simulated by applying ADS software and fed through strip line feeding. The uniqueness of this design is the antenna can support 2.4-GHz Bluetooth and/or 3.5-GHz WiMAX and/or 5.8-GHz WLAN systems and/or 6GHz 5G systems. The advantage of this design is that it overcomes the problem of conventional reconfigurable antennas of serving one frequency band at a time. Maximum radiations are directed normal to patch geometry and shape of patterns is somewhat similar to a dumble shape in the upper hemisphere. The antenna design, simulation, and measurement results are presented. The antenna shows similar radiation patterns with low cross-polarization levels at all its operating frequencies. The simulated and measured results are in good agreement.  This Reconfigurable Patch antenna is specifically designed for the application of 5G Mobile communication systems.
