Popular arrays with such sidelobe behavior are Taylor, Gauss, Gegenbauer, and second-kind Chebyshev. In this paper, we propose a closed-form method for the design of pencil-beam arrays with a prescribed sidelobe level. The method exploits the leastsquares approximation of a raised cosine function in the azimuth domain, thus bringing the beampattern with slowly decaying sidelobes. For common numbers of excitation coefficients and sidelobe levels, the proposed arrays simultaneously exhibit the optimum beamwidth, dynamic range ratio, and directivity.","PeriodicalId":135770,"journal":{"name":"2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115704129","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 considered idea used a known numerical method based on the moment technique simplified by equivalent circuits approach (MoM-GEC) to describe the electromagnetic responses in spectral (or Floquet) and spatial domains. A beamforming technique related to Fourier transformation is proposed when a far-field transformation algorithm for plane-rectangular scanning is highlighted to control the main radiation beam pattern in a particular direction toward a target, as given in various scanning scenarios. To demonstrate the efficiency of the given method, many simulation results are carried out using matlab.

We measure the roughness parameters of rough surfaces and then import them into a 2D model to compute the scattered fields under various surface illuminations. The validity of this approach is demonstrated by comparing the simulation results with measurements. Besides, we use the 2D model to simulate rough surfaces of a wide range of roughness parameters and perform a qualitative analysis on the scattering patterns. We show that, for most common building materials of moderate roughness, increasing the root-mean-square height of the rough surface reduces the maximum reflection and increases diffuse scattering. On the other hand, increasing the correlation length of the rough surface will lead to lower maximum reflection and diffuse scattering.","PeriodicalId":135770,"journal":{"name":"2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116763324","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 constructed by array four loop antennas smaller than the wavelength of the operating frequency. The proposed antenna expands the interrogation zone at near-field and has a uniform field distribution because each straight line at the top and bottom of the substrate in the small loop utilizes ODC to canceling current and form one large loop electrically. In addition, the proposed antenna has a lower E-field compared to the conventional single loop, which prevents detection of adjacent tags outside the interrogation zone. The proposed antenna has a maximum read range of 48 mm and the detailed characteristics of the proposed antenna are verified by comparing the simulation and measurement results.","PeriodicalId":135770,"journal":{"name":"2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117182186","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}

Wireless frequency synchronization represents one of the basic coordination requirements in coherent distributed phased arrays. When combined with inter-node ranging, frequency synchronization enables separate nodes to implement distributed beamforming for various applications. We build on a novel spectrally-sparse two-tone ranging waveform combined with a self-mixing receiver circuit that demodulates a frequency reference from the two-tone separation and is used to synchronize the local oscillator. Measurements conducted outdoors demonstrate basic synchronization between two wireless systems, providing a framework for future distributed beamforming with widely separated nodes.","PeriodicalId":135770,"journal":{"name":"2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121099857","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}
