Design of a Compact Monopole Antenna for Super Wideband and 5G Applications

Abstract

Numerous technologies have been employed as the demand for data requirements and high resolution in wireless communication systems increase. Increased research has led to the evolution of numerous antennas including but not limited to monopole antennas and dipole antennas. An innovative design monopole antenna for Ultra-wideband applications is presented in this paper. The design incorporates a cut-in rectangular patch with, two notches at the upper and lower corners of the patch and a microstrip feed line. The proposed compact antenna is designed on a Rogers RT/Duroid 5880 substrate of dimensions 22 mm x 28 mm x 15 mm which shows its compactness. Testing and simulation results generated from the proposed design showed good Ultra-wideband characteristics between 3.8 GHz and 50 GHz frequencies at 10 dB return loss. The performance of the antenna was tested at the sub-6 GHz spectrum and millimeter-wave spectrum specifically 6 GHz and 28 GHz. The proposed antenna has super-wide bandwidth with good impedance matching and isolation. The antenna’s simulated performance characteristics make it applicable in radar, sonar imaging in handheld devices in the Ultra-wideband spectrum, and 5G MIMO application.
