Dual Broadband Coplanar Waveguide-Fed Slot Antenna for 5G Applications

In this paper a dual broadband CPW-Fed slot antenna is presented for 5G applications. This antenna operates at the lower and the millimeter (mm) wave bands, especially the 28/38 GHz of the mm-wave bands of the 5G wireless communications. The proposed antenna is compact with a size of 20 × 15 mm
²
. It has two bands which are extended from around 3.4 to 7.3 GHz and upper band extended from 20 to 38 GHz. These bands are achieved by using a rectangular slot with a triangle strip, two shunt stubs and a rectangular patch inside the slot. The results show that this antenna has impedance bandwidth of 80% and 66.6% for the lower and upper bands respectively. CST Electromagnetic simulator is used to simulate the proposed antenna which it provides omni-directional pattern and good gain over the operating two bands.
