Combined with the characteristics of reflector antenna, through focal field analysis and performance comparison under various designs, this paper presents the specific array design method of 1.25 GHz phased array feed. The final designed phased array feed can achieve three times the beam width of the telescope field of view at the working frequency of 1.25 GHz, the array size is 0.525m, the array element spacing is 0.437 times the wavelength, the array arrangement mode is hexagonal arrangement, and the final number of array elements is nineteen, of which the hexagonal subarray of 7 elements form one beam. Although the above array design parameters are not the optimal solution under the same conditions, the relevant steps can guide the array design of reflector antenna phased array feed, and also provide a reference for the later design of broadband and ultra wideband phased array feed array.","PeriodicalId":442568,"journal":{"name":"2022 IEEE 9th International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications (MAPE)","volume":"55 3 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":"130494295","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}

WiFi and ZigBee are the two most commonly used IoT devices in IoT environments. They have the advantages of low communication delay, high speed, low cost, and easy deployment. Since the spectrum of WiFi and ZigBee overlap, ZigBee signal will affect the transmission of CSI signal. We propose a CTC technique based on machine learning and deep learning, which uses only WiFi channel state information (CSI), and can distinguish whether there is ZigBee signal transmission in WiFi signals by classifying WiFi channel state information. In this paper, machine learning classification methods and deep learning methods are used to classify CSI sequences respectively. We extract the features of 8 CSI sequences to improve the accuracy of machine learning classifier and LSTM classifier, and adopt transformer network classifier to further improve the classification accuracy. In our experimental dataset, the highest accuracy rate can reach 94.9%. The evaluation results show that the accuracy of this method is significantly higher than the existing classification methods.","PeriodicalId":442568,"journal":{"name":"2022 IEEE 9th International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications (MAPE)","volume":"28 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":"132569739","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, the current generation method of vortex wave is defective, especially the design of vortex wave antenna with broadband and low RCS still faces great challenges. In this paper, an ultra-broadband stealth vortex wave antenna is proposed based on metasurface (MS). After y-polarized spherical wave passes through the MS, the MS converts y-polarized spherical wave into x-polarized vortex wave at front side. When y-polarized wave illuminates the MS from back side, the antenna array scatters y-polarized reflected wave to realize diffuse scattering function and reduce the backward RCS of the antenna system. By exciting the MS with horn antenna, a stealth vortex wave broadband antenna system is realized. The broadband antenna system has both high gain vortex wave radiation performance and low backward RCS scattering performance in the same frequency spectrum simultaneously. The experimental results show that the 3 dB gain relative bandwidth of the stealth vortex EM wave antenna is 58% (11 GHz~20 GHz). Besides, the RCS of the antenna system can be reduced more than 10 dB between 11.3 GHz to 20 GHz (relative bandwidth is 56%).","PeriodicalId":442568,"journal":{"name":"2022 IEEE 9th International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications (MAPE)","volume":"7 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":"133737129","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 solve this problem, we propose a null broadening algorithm based on covariance matrix reconstruction and virtual antenna technology in this paper. According to eigenvector correlation we reconstruct a sidelobe interference plus noise covariance matrix. Then we construct a projection transformation matrix using the interference steering vector and the reconstructed interference plus noise covariance matrix is processed. Finally, the covariance matrix is extended and adaptive beamforming is carried out combined with virtual antenna technology. Simulation results show that the null broadening algorithm can effectively suppress interferences and has good robustness.","PeriodicalId":442568,"journal":{"name":"2022 IEEE 9th International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications (MAPE)","volume":"31 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":"132006596","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}
