By adjusting the phase slope through three pairs of differential phase shifters, the flatness of the output ports phase differences is improved. Besides, size reduction is obtained by using transdirectional couplers. Based on the designed equations, a prototype operating at 5.8 GHz is fabricated and measured. The fractional bandwidths (FBWs) for more than 10 dB return loss and isolation are 31.21 % and 45.17 %, respectively. Under the criterions of 1- dB amplitude imbalance and 5° phase derivation error, the measured FBWs are more than 20.86% and 16.03%, separately.","PeriodicalId":219307,"journal":{"name":"2022 Asia-Pacific Microwave Conference (APMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134139101","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}

For the drone to fly with microwave energy, the rectenna must be attached to the bottom of the aircraft, which causes interference to mission equipment such as cameras. The conical beam with a null in the center avoids this problem. In the case of microwave power transmission, the receiving antenna is in the Fresnel region, so the beam must not only be nulled in the center but also focused toward the receiving antenna. Therefore, in this study, we designed the size of the antenna and its amplitude distribution using the electromagnetic field of the LG-mode. Simulation results with a planar array antenna show that the transmitting antenna of 2.1 m radius can transmit the 24 GHz beam with the air-core ratio of 14% to the receiving antenna of 0.5 m radius located at 40 m above the ground.","PeriodicalId":219307,"journal":{"name":"2022 Asia-Pacific Microwave Conference (APMC)","volume":"272 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133887884","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 insertion depths of two movable posts in each resonator allow for bandwidth variation at a constant center frequency. A variation of the gap between the dual-post changes the center frequency between 1.9 GHz to 2.9 GHz, resulting in a center frequency tunability of $tau_{f0}=34%$ and a bandwidth tunability between $tau_{min}=50%$ and $tau_{it max}=80%$.","PeriodicalId":219307,"journal":{"name":"2022 Asia-Pacific Microwave Conference (APMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122410117","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 conical beam and the coaxial all-phase reception brings painful difficulties. As a promising solution to overcome this difficulty, an OAM multiplexing transmission method is proposed for use in a satellite formation relay scheme in this paper. Specifically, the channel model of the OAM wave from the base station to the relay satellites and then forwarded by relays to the central receiver is established and analyzed. In order to explore the feasibility of the scheme and its influencing factors, we analyze the influence of orbit distribution and random jitter on channel capacity based on the orbit parameters of actual satellite formations. The simulation results show that the uniform and evenly spaced satellite formation has the highest multiplexed channel capacity and anti-interference performance.","PeriodicalId":219307,"journal":{"name":"2022 Asia-Pacific Microwave Conference (APMC)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122572836","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}

In conventional wideband filtering antenna, a fractional bandwidth of over 20% is difficult to realize because a single patch has a lower limit of radiation Q factor. To solve the problem, we propose a new wideband filtering antenna loading a parasitic element. As an example, we design a fifth-order filtering antenna with center frequency of 4.0 GHz and fractional bandwidth of 30%. The effectiveness of the proposed filtering antenna is verified by comparing the reflection and radiation characteristics between the measured results and the EM simulated ones.","PeriodicalId":219307,"journal":{"name":"2022 Asia-Pacific Microwave Conference (APMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121233037","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}

At the input, an active balun converts the single-ended input signal to a differential signal and drives the frequency tripler into the non-linear region. To improve the conversion gain (CG), the proposed frequency tripler is followed by a buffer stage and a totem pole (TP) output stage. It offers a peak output power of −3 dBm at 26.7 GHz with a 3-dB output frequency range between 24 GHz to 34.5 GHz, and achieves a peak CG of 27.2 dB at an input power level of −33 dBm.
