The main contribution of this structure is the utilization of the widely available substrate with a simple design to improve the power quality by harmonics suppression. Since the microstrip monopole antenna already offers wideband characteristics, the DGS is incorporated in the design to achieve a stop band in the undesired frequencies while widening the rejection band. The main objective of this paper is to achieve a focused frequency bandwidth centered at 3.5 GHz frequency with no harmonics for high quality antenna for future 5G application. To achieve this, a modified rectangular patch is designed to obtain wideband frequency at 3.5 GHz. Next, a DGS structure is placed at the ground plane of the antenna to ensure the undesired frequencies are suppressed for better power quality and wideband operating frequency at 3.5 GHz. Next, a DGS structure is placed at the ground plane of the antenna to ensure the undesired frequencies are suppressed for better power quality. The proposed work is designed and simulated using CST Studio Suite 2022. The results show that by implementing the DGS on the ground plane of the proposed antenna, the frequencies ranging from 4.3 GHz up to 8 GHz are successfully suppressed. Plus, even with the addition of the DGS structure at the ground plane of the antenna, the efficiency of the antenna remains high at 91.02% and there is negligible change in the radiation pattern. However, the gain of the antenna decreased by 1.53 dB.","PeriodicalId":171480,"journal":{"name":"2022 IEEE International RF and Microwave Conference (RFM)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124624566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared to its competing devices, the GS-GAA FinFET design exhibits a notable increase in the forward/reverse transmission coefficient and a decrease in the input/output reflection coefficient owing to the enhanced transconductance. In addition, the effect that channel doping and gate length have on the scattering parameters has been looked at as well. The major goal of this research is to establish optimal channel doping and gate length for future RF applications.

A 50-ohm coaxial cable is used to feed the antenna, placed at the appropriate position. The performance analysis of a dielectric resonator antenna with T slot configuration supported by substrate integrated waveguide (SIW) has been investigated. Parametric studies on various parameters to improve the performance in terms of gain, impedance bandwidth, surface current, and impedance matching behaviors are observed. The simulated result of the proposed dielectric resonator antenna supported by SIW shows a reflection coefficient of more than 10 dB in desired frequency at 3.5 GHz which is in good agreement with the simulated results. In this study, the gain of the T-slot antenna was 5.01 dB. All simulations are done using Computer Simulation Technology (CST) software.
