Therefore, we have carried out experimental measurement of RCS of different PEC targets in the anechoic chamber. These measurements were used to validate the numerical results obtained using the GB approaches which are: Gaussian Beam Summation (GBS) and Gaussian Beam Launching (GBL). In the numerical simulation, the used GB techniques are firstly combined with the asymptotic Physical Theory of Diffraction (PTD) method. After that, the RCS results are evaluated with the Method of Moment (MoM) and also with the experimental measurements.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115699464","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}

Since 5G operates at millimeter wave frequencies in the range 10–300 GHz, the design, developments and testing of antennas, embedded in 5G wireless devices, have been consequently influenced. For smart testing and diagnostics of 5G enabled devices, fast and accurate antenna measurement systems are needed to satisfy the short cycles in development, testing and production to which today’s antenna engineer are working. Multi-probe antenna measurement systems are based on a consolidated technology currently employed from 70MHz up to 18GHz. This paper, describes the recent advances in multi-probe technology as implemented in StarLab 50GHz, ideal for testing 5G application antennas in the 18-50GHz frequency range. Diagnostics and troubleshooting of antennas integrated in 5G enabled devices is enabled by post-processing using equivalent currents. To illustrate the testing capabilities, measured examples, including diagnostics on a 5G Millimeter-Wave Mobile Terminal are presented. The possibility to determine power density in the near vicinity of 5G devices by equivalent currents processing to verify compliance with safety normative is also presented.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116237658","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}

However, an airfilled such cavity at 1 GHz needs to be 250 mm in diameter. There is another problem as well: its limited applicability with very lossy samples, due to a too low Q value. This paper describes the development and properties of a metalized zirconia ceramic cavity for use at about 1 GHz. With its permittivity $varepsilon'=30$ its diameter becomes 40 mm instead of 150 mm for the airfilled version. Additionally and importantly, the dynamic range of the loss factor $varepsilon''$ is greatly expanded. The calibration procedure using numerical retro- modelling is described and a measurement example of a ternary alcohol mixture is carried out.

The antenna structure is simple, compact and only occupied a small space of 18×5.5×4.5 mm3. Pattern reconfigurability is achieved by using a dual band Branch-Line Coupler (BLC). BLCs are commonly used in balanced amplifiers and mixers for achieving good return loss, as well as spurious signal rejection. In antenna design area, couplers, particularly Ring Hybrid Couplers are used to get high isolation between ports. In this work, we propose the use of BLC for doing both decoupling antenna system and pattern reconfigurability. Simulated and measured S-parameters are presented in this paper. The measured results show that the proposed MIMO antenna system achieves in each band isolation between ports better than 25 dB, more than 80 percent efficiency and has a maximum gain of 2.74 dB.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"4 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120984278","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}

Because the antenna is not rotating, the radar can stare at targets and select long dwell times with no effect on the scan rate. High Doppler resolution can be achieved and used to detect small targets, such as drones, even in heavy clutter. Despite the staring array, targets moving with a variable radial velocity generate echoes with a time-varying Doppler frequency shift that limits the integration gain achievable with standard Fourier Transform based techniques. As a result, the number of pulses can be integrated remains limited to the effective coherent processing interval with a consequent suboptimal Signal to Noise Ratio (SNR). This paper presents the results of a set of simulations aimed at studying the integration gain efficiency of a staring radar of the type of the Aveillant Holographic radar for targets moving with a constant and non-constant radial velocity. The case of a target flying horizontally with respect to the radar boresight is investigated to show that compensation techniques can be potentially employed to maximise coherence on the target and the resulting integration gain.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125325692","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}

Another similarly current sector is that of UAVs (Unmanned Aerial Vehicles), which are increasingly used as supporting tools by the armed forces and for public security activities. This paper describes the activities carried out and the results obtained within the “PLASTIc” (PLatform Agnostic Sensors for opTImised design of midlife ship refitting) research project, that combines the above application areas. The demonstrator built for the research project is able to carry out a dual task: the measurement of high intensity electrical fields and the taking of pictures to enable the creation of an accurate 3D CAD model reconstruction of the naval systems. In order to fulfill these two tasks, a payload was developed consisting of the necessary electronics and sensors, which was integrated on-board an electrically propelled UAV. The specific research will address, as operational case, the testing after a midlife ship refitting.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130652812","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}

In this work a time domain image reconstruction algorithm is investigated. With this algorithm the memory requirement for the gradient calculation easily can expand beyond what can be fitted into the RAM memory of a computer. As a consequence, the hard drive has to be used for intermediate storage of computation data. This has serious implications on the execution time of the reconstruction algorithm. In this work we investigate what effect a reduction of the number of data points in the gradient calculation has on the reconstruction accuracy.
