The frequency range covered by this antenna is 8-13 THz. To improve the antenna’s gain, a proposed rectangular metasurface structure environment has been used. To strengthen and connect the layers, several plastic bases have been used, which do not have a destructive effect on the antenna’s radiation pattern. The use of the proposed rectangular metasurface structure medium has increased the gain by more than 10.5 dB compared to the conventional antenna. The maximum gain is 14.7 dB at 12 THz. The final dimensions of this antenna are 24 × 28 × 21.6 mm 3 at 12 THz.","PeriodicalId":166695,"journal":{"name":"International Journal of Electronics and Device Physics","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125468600","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}

An tennas are beneficial for a wide range of applications such as point to point communication, radio broadcasting, radar, and wireless LAN. However, maximum gain and maximum directivity with low losses are the desired characteristics that are sought. In this paper, the novel design of ultra-directive microstrip Yagi design (frequency = 2.4 GHz) is simulated and analyzed. We used the FIT technique to obtain the optimized parameters (geometrical parameters) for the Yagi de sign. Also, the antenna parameters (gain and directivity), and the matching parameters (VSWR and S11) are simulated using the finite integral technique (FIT). The proposed design showed high directivity and high gain with a narrow beam. Additionally, the investigated design exhibits low loss power due to the low value of the backscattering and also S 11 value. The measured results for the matched parameters of the investigated design are taken from the network ana lyzer. For our proposed design, the experimental results are very close to the simulated results. The suggested Yagi antenna design may be beneficial for many applications including, Wi-Fi, Bluetooth applications, and wireless applications.","PeriodicalId":166695,"journal":{"name":"International Journal of Electronics and Device Physics","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134268095","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}

Three detection electrodes are triangularly arranged at regular intervals. Changes in the stray capacitance of each electrode due to the proximity of an object are observed. This method to detect a slight change in capacitance takes advantage of the fact that the transfer characteristics of a circuit comprising three reactance elements has the property of sharp phase changes near the resonance frequency. The position of an object is estimated from the balance of the signals of three channels, and its distance is determined from their magnitude. This method enables the three-dimensional proximity detection of an object. Especially, this method can be used to electronically recognize the gestures of a human hand with low-cost circuitry.","PeriodicalId":166695,"journal":{"name":"International Journal of Electronics and Device Physics","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129585566","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}
