Design and performance evaluation of a dual-band antenna for the 5G mobile communication

In this paper, the dual-band slot antenna operating at 32 and 42 GHz for 5G mobile communication is presented. The presented design consists of an elliptical slot with sectored radiating patch to increase the antenna bandwidth and also to minimize the interference between 5G and other communication devices. The simulated result shows that the presented antenna has dual-band at 30.5–32 GHz and 40.5–42 GHz, which has a bandwidth of 1.5 GHz each for reflection coefficient less than −10dB. The simulated radiation patterns showed that the presented antenna is highly directional with VSWR less than 2 and achieved frequencies lie within the proposed 5G band. This antenna has been designed and simulated on HFSS using Neltec substrate with dielectric constant of 3.2.
