Design and Analysis of a 5G Wide Band Antenna for Future Mobile Applications

摘要

The latest 5G technology is the one which has the capacity and power for very high speed data communication in order to fulfil the requirements for robotics, live events broadcasting, high definition streaming of the videos and autonomous driving. The wide-band antennas with high gain have taken place of conventional narrow bandwidth antennas having low gain since they are now needed for reliable 5G wireless communication. In this paper we have proposed an L-slot wideband 5G antenna for 5G wideband applications resonating at 39 GHz frequency band. The antenna has been designed on a 0.5 mm thick FR-4 substrate, having dielectric constant of 4.3. The proposed antenna has simulated S11 of -29.057 dB and realized gain of 4.142 dB for 39 GHz. In addition, the VSWR value obtained is 1.073 dB, which is acceptable for its future use. Overall size of the antenna is mm × 4.8 mm × 0.5 mm. CST Microwave Studio is the software which has been used to simulate the proposed antenna.
