SIW is designed to reduce the size and cost of rectangular waveguide (RWG) and make it easy to be integrated with planar component. There are many studies on SIW antennas have been carried out to improve bandwidth, one of the methods used is designing the slot model of SIW. This study discusses the efforts to increase the bandwidth of the antenna using the SIW dual Slot V shape Antenna facing out towards the center line SIW. The antenna is designed at a frequency of 10 GHz. Based on the simulation results obtained bandwidth of 803 MHz, and the measurement results of 780 MHZ. While the results of the radiation pattern simulation obtained an antenna gain of 8.7dB and the measurement results obtained at 9.52 dB.","PeriodicalId":170627,"journal":{"name":"2019 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122930413","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 blind estimation of the effective antenna scattering features is conducted in the angular spectral domain, exploiting the principle of circular convolution. Angular resolution improvement may be achieved through numerous techniques, and a well-known deconvolution approach, called the Richardson-Lucy iterative techniques, is used in this study for illustration purposes. The effectiveness of the proposed approach is demonstrated using both simulated signals and real acquisitions performed using an X-Band maritime navigation radar designed within the Diades Marine company. Results indicate that applying deconvolution techniques using erroneous antenna diagrams leads to numerous false alarms and globally poor discrimination performance. The proposed technique permits to overcome this limitation and reaches comparable to the ones obtained in the case of an ideal antenna diaaram.","PeriodicalId":170627,"journal":{"name":"2019 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128567621","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 standards were realized by two originally developed precision attenuation measurement systems based on the intermediate frequency (IF) substitution method. The first system works in the frequency range of 9 kHz to 1 GHz, built in the highest accuracy dual channel null detection configuration using an inductive voltage divider (IVD) at 1 kHz as IF reference standard. The second system functions to extend the frequency range of 1 GHz to 50 GHz, built in a simple single channel configuration using a step attenuator at 30 MHz as IF reference standard. Traceability of the IVD is obtained directly to the Japan national standard of low-frequency voltage ratio, however, the traceability of the step attenuator standard is obtained through calibration using the first system. Attenuation calibration and measurement capabilities range from 0 to 110 dB with a frequency range of 9 kHz to 50 GHz and an expanded uncertainty range of 0.002 dB to 0.068 dB.","PeriodicalId":170627,"journal":{"name":"2019 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123625694","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}

This condition is expected to have an effect to the electric field and the surface current direction. This paper performs a second order of the interdigital filter co-design with a proximity fed rectangular patch antenna.
