Firstly, a wideband BPF is achieved by using a SIR, by controlling the high order resonant modes through the impedance ratio and electrical length of the resonator. Secondly, a longer stub is loaded to the centre of the resonator, a transmission zero (TZ) and a resonant frequency produced in the lower passband of the BPF. Thirdly, another shorter stub is loaded to the center of the resonator, a TZ and a resonant frequency is achieved in the upper passband of the BPF. Thus the wide passband is splitted into three ones and a BPF with triple passband is realized. The structure is analyzed by equivalent transmission line model. Finally, a tri-band bandpass filter with central frequency of 2.4GHz, 3.8GHz, and 5.2GHz is designed and simulated to verify the structure.","PeriodicalId":211726,"journal":{"name":"2022 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"41 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114037642","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 transmitarray antenna is composed of a wideband feed antenna and a wideband transmission metasurface. The feed is an improved ultrawide band Vivaldi antenna. The wideband transmission metasurface consists of 30×15 cells, each of which consists of a tightly coupled dipole antenna and parallel metal lines. The concept of equivalent delay distance is introduced to design the transmitarray. To validate the design, a prototype operating from 3 to 9 GHz are fabricated and measured. Good agreement between simulated and measured results is observed. The measured results show that the antenna has a stable radiation pattern in the operating frequency band. The antenna gain is from 13.9dB to 22.2dB, and the aperture efficiency is greater than 21%. This can also hopefully be used for CATR based on its near-field properties.","PeriodicalId":211726,"journal":{"name":"2022 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"75 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":"114382971","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 scheme indexes multiple samples in a single clock cycle, which not only reduces DSP resource consumption, but also extends the bandwidth of conventional serial DPD to a higher rate, without being limited by the maximum clock rate. The corresponding digital predistortion (DPD) model is based on the generalized memory polynomial (GMP). Indirect learning and regularization method are also applied to make coefficients identification stable. The whole system can perform real-time DPD iterations, without commercial equipment as PC or Matlab. A 4.9GHz GaN Doherty power amplifier (DPA) MMIC module is used to validate the predistorter with a 100-MHz bandwidth signal. The results show good linearization performances with the adjacent channel power ratio (ACPR) below -48 dBc, meeting the requirements of the 5G communication standard.","PeriodicalId":211726,"journal":{"name":"2022 International Conference on Microwave and Millimeter Wave Technology (ICMMT)","volume":"102 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":"114599104","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}
