Simulation Results

In this work, tri resonance multi slot microstrip patch antenna which operates at three center frequencies of 11 GHz, 11.9 GHz, 15.7 GHz is designed and simulated. As a commercial simulation tool, Sonnet Suites, a planar 3D electromagnetic simulator was used. Details of the simulation results are presented and discussed. As a result, an input match of -6.88 dB at the resonance frequency of 11 GHz, an input match of -37.12 dB at the resonance frequency of 11.9 GHz, an input match of -29.49 dB at the resonance frequency of 15.7 GHz were observed. The gain was observed as 8.25 dB at 11 GHz and 4.82 dB at 11.9 GHz. Also, the gain was observed as 7.07 dB at 15.7 GHz. The patch has several symmetric slots and it’s well known that slots change the current distribution of the patch antenna.

Novel Approach

It is unavoidable to decrease the thickness of the substrate in order to obtain enough flexibility. Decreasing the height of the substrate lowers the gain of antenna and its bandwidth. Thus, it is challenging to provide operability for the flexible materials and it requires new approaches. This paper is shown that the using nano silver paste for the designed antenna causes better return loss rates (S11) and bandwidth. Also, the effect of sintering temperatures on the response of the antenna is analyzed for the range of 150 ° C to 350 ° C. The highest resonance frequency and the lowest return loss are observed at 350 ° C in this range. The SEM images of the antenna surfaces show that the nanoparticles in the paste group together with increasing sintering temperatures. When compared to the perfect conductor silver, better return loss and bandwidth are obtained.

Microstrip patch antennas (MPAs) are known largely for their versatility in terms of feasible geometries, making them applicable in many distinct circumstances. In this paper, a graphene-based tuneable single/array rectangular microstrip patch antenna (MPA) utilizing an inset feed technique designed to function in multiple frequency bands are used in a fifth-generation (5G) wireless communications system. The tuneable antenna is used to eliminate the difficulties caused by the narrow bandwidths typically associated with MPAs. The graphene material has a reconfigurable surface conductivity that can be adjusted to function at the required value, thus allowing the required resonance frequency to be selected. The simulated tuneable antenna comprises a copper radiating patch with four graphene strips used for tuning purposes and is designed to cover a wide frequency band. The proposed antenna can be tuned directly by applying a direct current (DC) voltage to the graphene strips, resulting in a variation in the surface impedance of the graphene strips and leading to shifts in the resonance frequency.
