FETs have the advantages of higher input power, higher DC output voltage, better availability over conventional Schottky barrier diodes. For the input circuit of the rectifier, a novel low pass filter based on defected ground structure (DGS) is implemented which blocks the harmonics produced from FET. For the output circuit of the rectifier, an output filter based on Class-F load structure has be designed to make the harmonics reflect back to the GaAs FET (MGF1801) transistor and eventually converted to DC power. In order to achieve fast and accurate simulation, the paper proposes a design method using Mentor Graphics IE3D electromagnetic simulation software and Agilent Advanced Design System (ADS) circuit simulation software co-simulation. The MW-to-DC conversion efficiency of the proposed rectifier achieves 71.5% with inputted power of 23dBm with a small size. This rectifier is extremely valuable in the high conversion efficiency rectenna when the received power is large.","PeriodicalId":197691,"journal":{"name":"2022 IEEE 10th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114218847","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 low-frequency band of the antenna uses the ultra-broadband printed dipole antenna form, and the high-frequency band uses the broadband printed dipole collinear antenna array, The two frequency bands are synthesized by a two-way combiner and impedance matched by a matching network. The antenna frequency band covers two frequency bands: 225MHz-678MHz and 1.4GHz-1.8GHz. Antenna VSWR is less than 3 in the frequency band. Good omnidirectional radiationwith gain variations less than 0.8 dBi in the azimuth plane has been obtained. Dual frequency antenna gain about 0 dBi for low low frequency band and about 4 dBi for high frequency bands are achieved. The antenna has the characteristics of wide frequency band, high gain and light weight, and can provide good omnidirectional radiation characteristics in the working frequency band.","PeriodicalId":197691,"journal":{"name":"2022 IEEE 10th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121107774","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}

Firstly, the array is divided into multiple first-stage subarrays along the horizontal plane. Secondly, each first-stage subarray is divided into four irregular second-stage subarrays through optimization of genetic algorithm. As results, an irregular phased array with beam-scanning angle up to $pm 60^{circ}$ and $pm 15^{circ}$ respectively at the horizontal and vertical planes is achieved.

Open rings are periodically etched into the transmission line (TL) of the antenna. Flaring grounds and tapered open rings are used in the transition regions to achieve the momentum and impedance matching between CPW and the SSPP TL. To transform the overpoweringly confined SSPP waveguiding mode to a radiation mode, elliptical patches are placed on both sides of the waveguide. Simulation results also demonstrate that the scanning angle of the LWA can be 96° within 4 GHz band range (8-12GHz) and the corresponding scanning rate is 2.40°/%. The proposed frequency scanning antenna may have potential applications in microwave wireless communication.","PeriodicalId":197691,"journal":{"name":"2022 IEEE 10th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125169533","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}

Therefore, users can be located by making rational use of the signal received by the antenna arrays. In the indoor nonline of sight (NLOS) scenarios, the traditional location method based on time of arrival, angle of arrival, and received signal strength, etc has poor location accuracy. Therefore, the channel state information (CSI) in massive MIMO systems can be used as location fingerprints to improve the location accuracy. However, in order to improve the accuracy of fingerprint location, a large number of fingerprint data need to be collected, and the sampling cost increases proportionally. Therefore, we propose to use the Generative Adversarial Networks (GAN) to expand the dataset of massive MIMO fingerprint. The experimental results show that the expanded fingerprint dataset can achieve better location accuracy than the real dataset in the scenarios with low SNR, and can achieve similar location accuracy with the real dataset in the scenarios with high SNR.","PeriodicalId":197691,"journal":{"name":"2022 IEEE 10th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":"70 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114034605","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}
