The investigation is also performed using a theoretical approach focused on synthesizing process. The use of Chebyshev function as weighting coefficient for linear array antennas with number of elements less than 10 shows that the variation of array-elements-number (N) with a constant inter-elements-spacing (d) can improve WML and provide notable impacts to SLL. While the variation of inter-elements-spacing (d) with a constant array-elements-number (N) yields to the WML improvement without significant effect on SLL. The theoretical approach is then validated by the experimentation with the error rate in SLL and WML of 1.68% and 3 %, respectively.","PeriodicalId":170627,"journal":{"name":"2019 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"1 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":"131127923","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}

It consists of 4× 4 elements where the microstrip line inset feeding method is employed to excite each antenna element. The characterization results show that the use of spiral shaped DGS yields the measured radiation characteristic to achieve the gain achievement of 10.47 dBi at the resonant frequency and the −10ddB bandwidth response of 140 MHz. These results are comparable to the simulated ones which are showing the potentiality of spiral shaped DGS incorporation for the radiation characteristics improvement.","PeriodicalId":170627,"journal":{"name":"2019 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"69 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":"121092975","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}

More specifically, a Line-Of-Sight (Random-LOS) testing scenario is addressed. The communication throughput is evaluated as the Probability of Detection (PoD) of a single bitstream based on the ideal digital threshold receiver model. The maximum deviation of throughput efficiency is computed as a function of the azimuthal sampling resolution for various generic antenna gain patterns. The coefficient of variation of the antenna gain pattern is introduced to evaluate the impact of the azimuthal sampling. The presented approach can be used to define the sampling resolution of the throughput performance of a device under test in Random-LOS OTA.","PeriodicalId":170627,"journal":{"name":"2019 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"44 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":"116216979","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}

Each antenna element consists of a rectangular feeding branch, an L-shaped slot and an L-shaped coupling branch. The slot and coupling branch are excited by the feeding branch to generate the low (3.45 GHz) and high (4.8 GHz) resonant frequencies. In particular, the L-shaped slot is set on the metal frame of the mobile handsets, which makes the antenna element and metal housing well integrated. A simplified antenna prototype is fabricated and measured. The simulation and measurement results, such as S-parameter, efficiency, envelope correlation coefficient (ECC) and 3D radiation pattern are presented.

The calibration is the most critical part in accurate measurement. Therefore, the need for high-accuracy calibration of high power transient electromagnetic field sensors, including amplitude calibration and frequency bandwidth calibration, has become increasingly urgent. However, IEEE Std 1309-2013 does not contain a specific calibration method for high power transient electromagnetic field sensors. In this paper, by analyzing the TEM cell and the monocone TEM cell, combined with the advantages of these two standard electromagnetic field generating devices, these two TEM cells are selected as the calibration devices for the transient electromagnetic field sensor. Unfortunately, the size of TEM cell, constrained with the calibration accuracy, decreases its frequency bandwidth. And the low frequency of monocone is unavailable due to its narrow time window. As a viable solution, the TEM cell is used for amplitude calibration, meanwhile the monocone TEM cell is used for frequency bandwidth calibration. Moreover, a practical and operational calibration process is proposed in this paper. The process includes the obtainment of the calibration coefficient $K$ in the amplitude calibration, as well as the determination method of the sensor's upper frequency in the bandwidth calibration.","PeriodicalId":170627,"journal":{"name":"2019 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"81 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":"127504512","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}
