The proposed antenna has been Electro-magnetically coupled at various points to improve its parameters. The design has a Tri-band type structure at center which is Electro-magnetically coupled at its base and further connected to the feed line of the antenna. A small rectangular patch has been embedded above the central Tri-band structure. The outer rectangular boundary of the design has been divided into two equal parts which looks like inverted U shape structure with a rectangular slot on the ground along with a Defected Ground Structure (DGS). The central Tri-band structure resonates in the Ku band region and the embedded rectangular structure makes antenna resonates in the Ka band simultaneously. The overall structure has a compact footprint of 35mmx25mm. The antenna has been simulated using Computer Simulated Software (CST) and various parameters and results have been recorded. Since the antenna has excellent Radiation characteristics with acceptable Gain and Directivity and has an even distribution of Surface current across the surface of the antenna. The proposed antenna has an excellent viability for wireless applications which demand small size, good Directivity, Gain and excellent radiation characteristics.","PeriodicalId":138339,"journal":{"name":"2020 IEEE International RF and Microwave Conference (RFM)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115994064","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}

The technique employs a simulation design using full wave software CST consisted of two slotted patch antennas at 2.4 GHz and a slab of FR4 that has been placed in between of the antennas. The S parameters (S11 and S21) were extracted from simulation and the electrical characteristics of FR4 were calculated using Nicolson-Ross-Weir (NRW) and Smith methods. It comes to the knowledge that the NRW technique has limitation in terms of material thickness which affects the value of permittivity and permeability of materials. Thus, a comparison has been made between these two methods by varying the material thickness of FR4 versus its permittivity and permeability. The thickness was varied from 5mm to 60mm. It was observed that these two techniques produce similar values of permittivity and permeability when the thickness has been varied up to 50 mm but differs when it was greater than 50 mm. On top of that, this paper also investigates the slotted patch antenna as a potential of RF sensor to investigate the unknown materials at 2.4 GHz.","PeriodicalId":138339,"journal":{"name":"2020 IEEE International RF and Microwave Conference (RFM)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128520795","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}

A single-layer of EBG structure mounted on semi-flexible FR-4 substrate and located above the radiating antenna patch with 70 mm. The proposed antenna based on the EBG structure is operating at 2.45 GHz for WLAN applications. CST MWS is utilized to evaluate the S11, matching impedance, resonant frequency, bandwidth, gain, and far-field radiation patterns. Parametric studies for the antenna design parameters with and without EBG planar array structure are investigated to obtain the optimal antenna performance at 2.45 GHz. The optimal antenna design based on the EBG array is fabricated on FR-4 substrate with maximum dimensions of 2.13λo × 2.13λo × 0.013λo mm3. It is noteworthy that introduced the EBG configuration significantly improves the antenna gain from 6.3 dBi to 13.4 dBi due to emerging the radiation beams towered the desired direction. Another achievement after adding the EBG structure is improving the aperture efficiency from 8.7% to 45.1% and increased the bandwidth by 18 MHz and enhanced the Half Power Beam Width (HPBW) from 77.1° to 42.1° and 118.9° to 35.8° along the elevation (θ) and azimuth directions (θ), respectively.","PeriodicalId":138339,"journal":{"name":"2020 IEEE International RF and Microwave Conference (RFM)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133673481","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}

The advantages of applying ECM versus discrete decoupling capacitors on compact PWB in terms of physical real estate and power integrity are also introduced. The work to investigate the feasibility of ECM substituting the discrete decoupling capacitors was implemented in two stages. In the first stage, the power integrity simulation was performed to analyze the PDN impedance of the power net of interest. In the second stage, the physical measurement of simultaneous switching noise (SSN) of the power rail of interest and the eye diagram of the Peripheral Component Interconnect express (PCIe) signal at 2.5 Gbps are carried out using oscilloscope. The jitter and SSN are diminished by 19 % and 9.3 % respectively when the PWB is laminated with ECM. Hence, the ECM is capable to serve as an alternative to the decoupling capacitors and facilitates the miniaturization of the PWB.","PeriodicalId":138339,"journal":{"name":"2020 IEEE International RF and Microwave Conference (RFM)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134490750","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}
