The Mathematical explanation for non-linearity compensation in Synthetic Aperture Radar (SAR) system is presented with proper signal processing chain. This processing approach shows improvement in target detection in simulation results. The frequency modulated continuous wave synthetic aperture radar with 0.25 GHz bandwidth and center frequency of 2.4 GHz is considered. The frequency of error signal is 50 KHz with a variation of sine function. In this case, the sweeping time of VCO is 10msec. More than one target are considered in simulation at a time with their different position to investigate and verify the proposed approach for compensation of VCO non-linearity in frequency sweep in VCO.","PeriodicalId":325720,"journal":{"name":"2020 International Symposium on Antennas & Propagation (APSYM)","volume":"602 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":"123202137","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 proposed antenna is designed by using simple stub geometry, multi-slit, and multi-slot techniques. In order to realize the proposed CP antenna, one stub has been embedded in the feed-line. By embedding stub in the feed-line and removing two slits from the ground plane, the S-parameters and axial ratio bandwidths have been noticeably increased. The MIMO antenna has a low-profile geometry and a dimension of 16 × 16 × 0.82 mm3. As a result, the three notched bands are good in existing interference bands of C-band (6.21 – 6.63 GHz), lower Ku-band (12.1−13.01 GHz), and lower K-band (18.24−21.01 GHz). In addition, the axial ratio bandwidth over the resonating bands are 3.79% (6.27 − 6.53 GHz), 24.20% (10.44 − 13.30 GHz), and 3.81% (18.81 − 19.54 GHz), respectively. The proposed MIMO antenna has a stable radiation pattern, sufficient gain, and low envelop correlation coefficient (ECC < 0.02) over the resonating bands, which is suitable for MIMO system applications.","PeriodicalId":325720,"journal":{"name":"2020 International Symposium on Antennas & Propagation (APSYM)","volume":"35 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":"128606099","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}

Planar microstrip line based design is adopted for making the comparator at lower band. Simulation result shows simulated impedance matching of > 14.4 dB at the input ports over 3.4-3.6 GHz. The maximum phase deviation at the sum port of the comparator is 2.2°.
