We used the PYNQ system to create a TCP service for communication with the CASPER library to enable remote real-time interaction, configuration, program loading and data reading from the hardware platform. The performance of the implemented CASPER platform is verified by designing firmware programs for GPIO, software registers, FIR digital filters and related experiments. The implemented approach provides rich development resources for FPGA development, shortens development cycle, improves development efficiency, and greatly simplifies the FPGA firmware design flow through platform-independent hardware and software.","PeriodicalId":442568,"journal":{"name":"2022 IEEE 9th International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications (MAPE)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116798377","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 design is composed of square metallic patches array and grid separated from a thin dielectric substrate where the varactor diodes are placed symmetrically. Adjacent metallic patches are connected with opposite electrodes, so that all varactor diodes are reverse biased in parallel. The results show that continuous modulation in the range of 2.798 GHz to 6.896 GHz (84.5%) can be realized by tuning the external bias voltage. The unit cell dimension is only 0.065λ0, which ensures that it has excellent angular stability within 75 degrees incident angles. Besides, it has stable response on both vertical and parallel polarized wave owing to its symmetry.","PeriodicalId":442568,"journal":{"name":"2022 IEEE 9th International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications (MAPE)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128439417","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 improve the interference cancellation radio (ICR), wideband interference signal is divided into subbands to reduce the computational bandwidth of the WAIC algorithm. In this paper, a method that fits the wideband interference signal by multi-tone signals is proposed to explicitly analyze the effect of the signal bandwidth on the cancellation system and quantitatively calculate the analytical solution of the ICR. Basing on the method proposed, the performance can be evaluated by the amplitude and phase difference between the received signals from the main antenna and the auxiliary antenna. Simulations and experiments are conducted to verify the theoretical analysis, and the results are consistent. Therefore, the analytical method proposed in this paper provides the design guidelines between the ICR requirement and subband bandwidth, which can reduce the complexity in the implementation of the WAIC system.","PeriodicalId":442568,"journal":{"name":"2022 IEEE 9th International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications (MAPE)","volume":"175 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130255038","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 simulation results confirmed that the proposed antenna array obtains a bandwidth of 4.2% (from 75.25 to 78.47 GHz), with a 10.7 dB max gain within the bandwidth. The proposed antenna array has advantages in gain and bandwidth, indicating a great potential in the field of the millimeter-wave radar antenna. In addition, quartz glass substrate with cavity structures provides a solution for relatively high radiation efficiency and gain due to its lower mass production cost and better electronic compatibility.
