The circuit structure tends to be complicated and not cost-effective because of the implementing local oscillators, low noise amplifiers, and mixers. To simplify the circuit structure and make it affordable, we employ a six-port method, namely, the homodyne scheme. We develop a six-port correlator based on a quadrature hybrid coupler on a printed circuit board. In this study, we demonstrated the performance of a six-port correlator in the 28-GHz-band on a transmission coefficient measurement.","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130792863","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, their application to monolithic microwave integrated circuits (MMICs) may severely decrease the overall system performance due to the high transmission loss, radiation loss, and reflection mismatch. This paper presents a wire-bonded patch antenna designed to operate in the frequency range from 81 to 83 GHz, which is a part of the IEEE W band. Obtained results show that the proposed structure demonstrates two major advantages. Firstly, it does not require any external matching network; hence, it can be directly connected to a 50-ohm contact pad of an MMIC die. Secondly, the wire bond radiation effect enhances the patch antenna gain at the broadside direction.","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131674784","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}

These residual error terms are propagated to determine the overall measurement uncertainty on the determination of extreme complex impedances.

The resonators are based on uniform cylindrical ceramic TM mode rods, which are connected to a metal core. This approach allows the cost-efficient realization of complex shaped dual-mode resonators. The filters are designed to use a pair of degenerated TM modes, which can be divided into a mode with electric as well as a mode with magnetic symmetry plane. Each dual-mode resonator contributes two resonances as well as one transmission zero (TZ) to the filter response. By varying the angles between the ceramic rods, it is shown that the filter parameters can be adjusted. Due to the TM mode operation, a proper contact between the ceramic rods and the metallic housing is required. Two different solutions are proposed in this paper: On the one hand, the cavity is made from a copper sheet. This approach enables the possibility that the ceramic resonators are soldered with the surrounding housing. On the other hand, threads are soldered to the ceramics, with which the ceramic core can be screwed to the housing. Second- and fourth order filters are manufactured as proof of concept.","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125861350","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}

Convergence rate, memory depth, digital pre-distortion enable and adaptive loop enable control options are explored to increase the performance of overall DPD system in practical cases. Look-up table (LUT) based algorithm is selected and system implementation details are provided. It is shown that convergence rate is important for the speed and the stability of the DPD system. Also other control options are required to implement an efficient DPD system. The system is modeled with Matlab-Simulink and then implemented on FPGA to see the resource utilization. Based on the simulations, the system can provide more than 10dB ACPR improvement within 500 μs when the convergence rate and the memory depth are selected properly.","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126726440","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}

This refraction highly influences the propagation of the EM-waves. Certain atmospheric conditions can cause EM-waves to get trapped within a duct. In these ducts blind zones may occur, where there is no EM-wave coverage. These blind zones show up in the results of ray tracing simulations. However, these codes provide no insight into the dependence of the blind zone on the atmospheric conditions and the transmitter height. In this research analytical expressions are derived for the range of these blind zones. The expressions have been verified by ray trace simulations for several transmitter heights under ducting conditions. Results show that the blind zone range can be accurately predicted.","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123318621","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 theoretical derivation of a Gaussian spectrum of small eddy turbulence is carried out to further reveal the key to the formation of the Gaussian spectrum of meteorological clutter. The simulation results and analysis show the correctness of the proposed model. The advantage of the proposed scheme is that, compared with some other schemes, the generated weather radar echo has better controllable in spatial distribution and spectral characteristics. Therefore, the proposed scheme can be better applied to the radar jammer and simulator based on digital radio frequency memory (DRFM).","PeriodicalId":177285,"journal":{"name":"2022 24th International Microwave and Radar Conference (MIKON)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124900385","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}
