Design of Multisegmented Dual Band Microstrip Patch Antenna for 5G Application

Abstract

A multisegmented dual-band rectangular monopole antenna with partial ground present in this
study. The proposed monopole antenna consists of a single patch with a partial ground of 17.5×5.83 mm and
three slots placed at edges of the patch to improve the impedance matching and fed by 50 ? microstrip line.
The proposed antenna is designed on a RoggerRT-Duroid5880 substrate with a permittivity of 2.2, a loss
tangent of 0, and a substrate thickness of 0.45 mm. The proposed design achieved maximum frequency band
of 28.8 GHz and 37.2 GHz with a return loss of -22.4dB and -24dB generating maximum bandwidth of
2.2GHz and 2.0 GHz respectively. Furthermore, the design achieves a maximum gain of 6.2dB which
reasonable for a single design. Besides that, the paper conducted and evaluated five substrate materials
analyzed the effect of design performance, for instance, return loss, gain, bandwidth, and resonant
frequency. Not only that, but the effect of different substrate thickness values also ranged from 0.45mm to
1.3mm have been examined and discussed in this paper by varying substrate thickness (h), each result is
recoded by simulating. Ultimately, all the electromagnetic designs and simulations of this study are
performed in the commercial full-wave EM simulator.
