With the novel multi-port topology, a new four-way FPD is designed by adopting only one modified multi-mode resonator, the resonant modes are flexibly controlled to achieve power splitting and quasi-elliptic filtering functions. Four isolated resistors are loaded in an easily realizable form to achieve high in-band isolation. In comparison with other existing designs, the proposed multi-port FPD design stands out by not only its satisfactory operation performance, but also compact multi-way topology with only one multi-mode resonator. For demonstration purposes, the designed triple-mode FPD is simulated by the EM simulator Ansys HFSS, which further validates the feasibility of the design. Results show that the new FPD exhibits wide stopband with five transmission zeros outside the passband, 20dB harmonic suppression up to 7.85 GHz (2.8f0 (f0=2.8 GHz)).","PeriodicalId":141204,"journal":{"name":"2021 IEEE International Workshop on Electromagnetics: Applications and Student Innovation Competition (iWEM)","volume":"351 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115465804","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}

Among the mainstream designs, planar inverted F-antenna (PIFA) with shape of button has attracted extensive interest because of its low profile, low cast and easy to integrate with clothes. However, the narrow bandwidth character of PIFA brings challenges to the design of wearable button PIFA. To solve this problem, a compact button PIFA with parasitic patch and U-shaped slot structure is developed in this paper. Compared to the typical dual-band PIFA, the proposed antenna shows a better bandwidth in both two working frequencies. According to the simulation results, the proposed antenna has 200 MHz low frequency bandwidth (2.3 GHz~2.5 GHz) and 2.5 GHz high frequency bandwidth (5.15 GHz~7.69 GHz), which is much higher than similar researches in the literature. The proposed antenna shows two different types of radiation patterns, a monopole type pattern in the 2.4 GHz band and a broadside type pattern in the 5 GHz band, in order to meet the requirement of multi-scenarios communications. From the simulation results, a satisfying efficiency of about 90% is obtained.","PeriodicalId":141204,"journal":{"name":"2021 IEEE International Workshop on Electromagnetics: Applications and Student Innovation Competition (iWEM)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114639734","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}

Different from the traditional indirect learning architecture of DPD that directly estimates the post-inverse model of the PA, the proposed architecture firstly simplifies DPD model through the optimal basis set selection module based on compressed sensing (CS). Then the model coefficients are estimated through the behavior model identification algorithm and replicated to the DPD. It can reduce model parameters while reducing the computational complexity and improving the stability of the system to achieve the effect of simplifying the model of the PA. Finally, the effect of improving the linearization of the PA is achieved. To achieve our proposed structure, we use a 20 MHz long-term evolution (LTE) signal to drive a 35 dBm Class-F power amplifier. The experimental results show that the adjacent channel power ratio (ACPR) and the normalized mean squared error (NMSE) is significantly improved compared with no DPD.","PeriodicalId":141204,"journal":{"name":"2021 IEEE International Workshop on Electromagnetics: Applications and Student Innovation Competition (iWEM)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128142012","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}
