Abstract

In this research paper, substrate integrated waveguide (SIW) was proposed as a technique by realizing bilateral edge walls to produce a compact 5G beam-steering antenna at 24 GHz. The beam forming network is produced using SIW directional coupler perform as 2×2 Butler Matrix (BM) fed with SIW slotted waveguide antenna array. The output signal is steered from -29 degrees and +29 degrees when the signal is fed to the respective input ports. If one of the input ports is fed, the signal is evenly distributed between the adjacent output ports with 90 degree constant phase shift. The compact size of directional coupler was designed by longitude slots on the surface of SIW substrate with bandwith of 16.85% at the operating frequency. The proposed antenna produce gain of 6.34 dB at operating frequency and the promising outcome of the beam steering make proposed design suitable for 5G communications especially with tracking capabilities.

Abstract

This paper presents the simulation design of a high-gain antenna using zero refractive index fishnet metamaterial (MTM) perforated on PDMS-Magnetite substrate for vehicle-to-vehicle (V2V) communications. In order to design the MTM, magnetite nanoparticles, 10-nm iron oxide (Fe3O4) are dispersed into polydimethylsiloxane (PDMS) matrix. Subsequently, the unit cell is designed by removing the circular hole with radius of 3.69 mm on the PDMS-Magnetite substrate layer and arranged in 5×5 array fishnet configuration. This optimized MTM is inserted between the antenna design and pure PDMS substrate to improve the gain. The characteristic of the respective unit-cell is investigated to operate at 5.9 GHz and the effectiveness of MTM is performed by comparing the antenna performance with and without MTM. The unique characteristics of zero refractive index transform the diverging wave into plane wave for perfectly parallel wave impact on the design to improve the directivity and gain of the antenna. The proposed MTM into design improves the antenna gain to 7.36 dB without having to compromise other antenna parameters of return loss, Voltage Standing Wave Ratio (VSWR), gain, directivity, efficiency, current distribution, radiation pattern and bandwidth. These advantages has made proposed antenna as a suitable candidate for V2V in Dedicated Short Range Communication (DSRC) application since high-gain directional antenna is required to increase the sensitivity towards signals coming from certain direction.
