X-Shaped Slot Antenna for Sub-6 GHz 5G Application

In this paper, a slot antenna with wideband characteristics is newly designed and proposed for use in sub-6 local 5G band. The slot antenna is in the shape of X character. In this design, a microstrip line is electromagnetically coupled to the feeding point at the center portion of the slot antenna. A microstrip tapered line is used for impedance matching and connecting to the 50 $\Omega$ input port. Throughout this paper, the antenna characteristics are evaluated by using the Finite Element Method (FEM) in a commercial simulation software (EMPro). From simulation results, −10dB impedance bandwidth is obtained within 3.2 GHz to 5.1 GHz, which is about 1.9 GHz bandwidth and realized gain has a peak value of 11 dBi at 4.7 GHz.
