In this paper, we introduce a compressive sensing (CS) based data measurement scheme which only uses a small sample of the total frequency points to increase the data acquisition speed. Typically amplitude information is used in these schemes. However, for some applications that require a high precision range measurement of the target, the use of phase information of the target's profile is also needed besides the amplitude information to improve the ranging precision; which is challenging. In this paper, we analyze the parameters of CS based method, which affect the accuracy of the recovered phase information of the target in detail. Simulation by an ideal point target and actual measurements by using our developed SFCW radar are carried out to investigate the effects of these parameters.","PeriodicalId":6554,"journal":{"name":"2016 IEEE MTT-S International Microwave Symposium (IMS)","volume":"23 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74220594","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 use of quarter-mode cavities provides a significant size reduction compared to regular SIW cavities, while preserving most of the advantages. The proposed filter comprises four side-coupled cavities, and the use of cross-coupling permits to introduce the transmission zero. The cross-coupling is due to thin metal strip outside the cavities, and it can be easily controlled to locate the transmission zero at the desired frequency. A four-pole filter operating at frequency of 4 GHz, with a transmission zero very close to the passband, was fabricated and measured. The proposed filter has a footprint of 41×28.5 mm2, corresponding to 0.55 λ0×0.38 λ0, where λ0 is the wavelength in vacuum at 4 GHz.","PeriodicalId":6554,"journal":{"name":"2016 IEEE MTT-S International Microwave Symposium (IMS)","volume":"4 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74336670","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}

A sequence of switchable couples of coils, connected in series or in parallel, is adopted at the fixed transmitting link side; the geometry of the moving receiver is optimized to keep the coupling factor, and thus the power transfer, constant during the movement. First the analytical formulation of the link coupling factor is derived as a function of its circuit-equivalent parameters computed by full-wave simulation. Then selected geometry parameters of the receiver side are optimized to keep the coupling factor constant while the link is moving. A set of TX-RX arrangements are simultaneously analysed to emulate the sliding movement of the WPT-Mob. The final optimized geometry demonstrates that a constant power transfer on-the-move is enabled, even for variable TX-to-RX link distances. Design and experimental verification are carried out for a geometry suitable for medium power transfer (tens of Watts) at 6.78 MHz, but the method is formulated in such a way that the system can be scaled up and down to accomplish different application needs.","PeriodicalId":6554,"journal":{"name":"2016 IEEE MTT-S International Microwave Symposium (IMS)","volume":"1 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73763991","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}

Under this closed-loop control, in hold mode, the droop rate of the single-ended outputs is reduced to 20 mV/ns. InP-CMOS interconnect parasitics are isolated from the high-speed signal path by isolation resistors and active bootstrapping.

Recently, the directional parametric conversion effect in time-varying transmission lines (TVTLs) has been utilized to develop nonmagnetic nonreciprocal components operating like circulators [1, 2]. In a TVTL, the two frequencies, the original RF and the up-converted RF, are cross-coupled through a single-tone carrier. Such property can be used for a frequency-tunable high-gain narrowband amplifier through the creation of the sharp resonance at the up-converted frequency. In this work, the concept of the frequency-tunable notch amplifier based on the TVTL is validated and demonstrated with analysis and experiments. We propose to form a feedback loop of a TVTL in one of its practical implementations called Distributedly Modulated Capacitors (DMC). The narrowband gain of the notch amplifier can be tuned over a wide frequency range by just tuning the carrier frequency that modulates the TVTL. An experiment prototype on a Rogers board demonstrated larger than 17 dB gain with a less than 10 MHz bandwidth at a center frequency tunable from 1.48 to 1.65 GHz.","PeriodicalId":6554,"journal":{"name":"2016 IEEE MTT-S International Microwave Symposium (IMS)","volume":"19 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84591227","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}

To avoid such risk, oversized margins are used. Multipactor simulations are used to get voltage threshold predictions. Since the power breakdown depends on the Total Electron Emission Yield (TEEY) curve a sensitivity study has been made to determine which parameters of the TEEY properties are critical. An evaluation of multipactor threshold sensitivity to TEEY curve variations is realized and two critical parameters are found for parallel-plate geometry: first cross-over energy and the curve definition for incident electron energy between the first cross-over and the maximum curve energies. Six TEEY models and their accuracy to predict voltage threshold are compared. Electron emission experimental measurements have to be accurate on the first cross-over energy and TEEY model must respect this value to obtain coherent multipactor voltage threshold.","PeriodicalId":6554,"journal":{"name":"2016 IEEE MTT-S International Microwave Symposium (IMS)","volume":"18 10 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84615152","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}
