The individual truncated corner elements are left-handed circularly polarized and resonate at 12.5 GHz. To achieve the high gain, the $2times 1$ array is designed using a uniform power divider. In the proposed 4-port structure, the sum pattern in elevation and azimuth planes can be achieved by exciting the ports. In order to achieve the difference pattern in both planes, left and right side $2times 1$ arrays are placed in the opposite direction to each other along the x- and y-axis. At 12.5 GHz, the sum and difference patterns gain are 10.20 and 10.40 dBic, respectively, in elevation and azimuth planes. In addition, a low sidelobe level, as well as a null depth of −45 dB for difference patterns, are achieved in both planes. The proposed compact single-layer structure is applicable for monopulse tracking applications.","PeriodicalId":201547,"journal":{"name":"2021 IEEE Indian Conference on Antennas and Propagation (InCAP)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125216198","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}

Moreover, radar systems have been more complex and involve many subsystems. These subsystems are also required to be tested during their development stages to solve unforeseen problems that may occur otherwise in field integration. Radar Target Simulators (RTS) are one of the many tools for testing radar at RF level. Its features enable in testing radar critical parameters. These tests are critical for radar mission preparedness. The day-to-day operation of radar is achieved using RTS. Also, it is used as a test tool for development of any subsystem, because of its capability to inject known targets. High speed target generation helps few classes of radars to test their capability to track high speed targets as these targets are rarely available in real scenario. This paper describes a mechanism to generate targets for different bands using common IF chain after down conversion.","PeriodicalId":201547,"journal":{"name":"2021 IEEE Indian Conference on Antennas and Propagation (InCAP)","volume":"191 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124248840","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 MIMO antenna consists of two radiating monopole elements placed orthogonal to each other with inverted U-shaped slot and U-shaped slot for dual band dispensing. The orthogonal placement of radiating elements provides sufficient amount of isolation between the two input ports and isolation of less than −22dB is achieved for entire range of frequency operation. A total volume of 20mm x 32mm x 1mm is occupied by total MIMO antenna system. Polarization diversity is obtained because of the orthogonal placement of radiating elements. By using PIN diode placed in the slots provided for notching characteristics, reconfigurable nature of band notches can be obtained The envelope correlation coefficient is less than 0.01 between the two monopoles. The suggested antenna is considered jeans cloth as substrate with dielectric constant of 1.67 and it has impedance bandwidth from 3.38GHz to 12.78GHz with two notch bands. One notch band is from 5.12GHz to 5.5GHz covering WLAN band and another notch band is from 7.98GHz to 11.4GHz covering X-band.
