The proposed LNA implements a passive notch filter in the form of U-Shaped defected microstrip structure (DMS) to eliminate the interference in WLAN band at 5 – 6 GHz. This design is based on negative feedback and inductive source degeneration which gradually increase the stability while providing wideband characteristic as well as gain flatness throughout the frequency band. Furthermore, this design implemented a multi-section quarter wave transformer as wideband matching which to improve the input and output matching. The LNA has been fabricated on FR4 substrate microstrip. The measured gain is better than 10 dB, a noise figure of 1.9 – 3.8 dB with a return loss of less than 8 dB. The interference rejection managed to achieve more than 25 dB at 5.5 GHz. This proposed structure is useful for RF/microwave front-end subsystems, especially in interference rejection.","PeriodicalId":111726,"journal":{"name":"2018 IEEE International RF and Microwave Conference (RFM)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132243398","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 prediction based on neural network is easier as it does not involve complicated empirical expressions and also it does not require special details such as the volume fraction, and dielectric constant of each element in the mixture which is necessary for dielectric mixing models. Dielectric measurement based on APC 7 connectors is carried out to obtain the dielectric properties of the cement-graphite mixture with different percentage of graphite for training purpose. The comparison of predicted results shows that Radial Basic Function introduces less error in prediction compare to Multilayer Perceptron. The discrepancy presented by the Radial Basic Function is less than 0.025 and 0.16 for dielectric constant and loss factor respectively in the frequency range between 100 MHz to 2000 MHz.","PeriodicalId":111726,"journal":{"name":"2018 IEEE International RF and Microwave Conference (RFM)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131769717","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 patch antenna has been designed, simulated, fabricated and tested successfully. Two types of antenna material were chosen as the antenna substrates. They were Polymethyl methacrylate (PMMA), a compounded synthetic resin produced from the polymerization of methyl methacrylate and Polylactic acid (PLA) which is extracted from fully renewable resources such as corn, sugar beet or rice. The PMMA and PLA both have dielectric constant of 2.546 and 2.6 respectively. The PMMA and PLA substrates were prepared using hot press machine at the same thickness of 1.6 mm. The patch antenna based on PMMA and PLA substrate were designed at operating frequency of 2.45GHz. It was observed that, both substrates PMMA and PLA have simulated return loss of 16.36 dB and 19.65 dB respectively. Then, the measured return loss were observed at 18.98 dB and 16.15 dB for PMMA and PLA respectively. The radiation pattern was observed to have similar trend for both substrates. In order to verify the performance of the newly develop substrate as patch antenna, FR4 was selected, designed and tested as patch antenna at the same operating frequency.

Recently, the idea of using SoG radar have become increasingly attractive due to the demands in accurate velocity measurements for vehicle safety systems. Despite SoG developments, assessments on the SoG uncertainty when moving on bumpy surface such as on off roads is not yet available. In this paper, we consider the use of SoG radar with 4 diverging beams. We present the theoretical accuracy assessment of this approach. Based on its measurement geometry, a simple derivation is developed to approximate the accuracy of the method. The results from the analysis shows that the 4-beam radar system can significantly minimise the error when moving on bumpy surface.","PeriodicalId":111726,"journal":{"name":"2018 IEEE International RF and Microwave Conference (RFM)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128856915","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}
