However, these systems demand strict time synchronization among receivers, which is laborious to deploy in indoor scenarios. To tackle this problem, we propose a novel localization scheme that can achieve target localization without the need for time synchronization. By utilizing a master-slave archi-tecture, the proposed scheme calculates the difference of carrier phase to derive the target's location accurately. Simulation results show that the proposed scheme can achieves high localization accuracy with a median error of 51.6 cm under a asynchronous condition.","PeriodicalId":211726,"journal":{"name":"2022 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"41 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114347853","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 consists of two stacked radiators fed by a Wilkinson power divider. By cancelling out the left-handed circular polarization (LHCP) fields in the backward direction and superposing right-handed circular polarization (RHCP) fields in the broadside direction, which are radiated by two radiators, the proposed antenna radiates a RHCP wave with a front-to-back ratio of 14 dB in the L1 GPS and B1 BD bands. With the radiation cancellation, the proposed GPS antenna has a compact size of 50mm×50mm×12mm.

First of all, on the premise of selecting the four-port network, the port equivalent impedance is obtained according to matching and isolation conditions. In addition, design a frequency reconfigurable matching network (MN) to match the port equivalent impedance to the port impedance across the entire frequency range. Last, by connecting the MN to the four ports, the adjustable operating frequency of the rat-race coupler is realized. This design method can simplify the coupler design. In order to verify the above proposed design method of reconfigurable coupler based on port equivalent impedance, we designed and measured a frequency reconfigurable rat-race coupler. The measured results show that the working frequency of the proposed coupler is continuously adjustable from 0.82 GHz to 2.26 GHz. In addition, the return loss and isolation are always better than 21 dB in the working frequency range of the coupler. Compared with similar couplers, the main advantage of this coupler is its superior performance over a comparable frequency adjustment range.","PeriodicalId":211726,"journal":{"name":"2022 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114813680","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 phase shifters in the RF front-end are applied to control the beam scanning. After pointing the transmitting beam to a specific direction, the receiving beam searches for the target position using digital beamforming technique, and then switches to the next transmitting beam, thus the radar can detect and locate the target in a wide two-dimensional domain, and the target distance can then be achieved from the received IF signal. It greatly reduces the number of RF channels while ensuring imaging accuracy. The experiment results show that this architecture can be well used in imaging systems.","PeriodicalId":211726,"journal":{"name":"2022 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"273 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114532512","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}
