Kirigami, a paper cutting and folding technique, can be applied to the design of reconfigurable antennas to introduce more flexibility and simple fabrication. In this paper, a kirigami-inspired reconfigurable antenna with one omnidirectional and two unidirectional beams is presented. The proposed antenna is composed of one monopole antenna, placed at the center of a ground plane, and two foldable kirigami parabolic reflectors. The parabolic structure enhanced the peak gain of the proposed antenna by 2.08 dB compared with its origami-based counterpart with a plane reflector. The simulated −10 dB reflection coefficient bandwidth is 13.37% for the omnidirectional mode and 10.23% for the directional mode.","PeriodicalId":180982,"journal":{"name":"2021 United States National Committee of URSI National Radio Science Meeting (USNC-URSI NRSM)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122980434","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}

A commercially available conductive filament, Electrifi has been lately reported by multiple researchers as a potential candidate for replacing traditional copper traces on printed circuit boards using additive manufacturing technologies. Using the fused filament fabrication method of additive manufacturing, this paper presents a 3D-printed microstrip patch antenna based on an improved version of conductive Electrifi filament on a planar TMM4 substrate for space-born applications, such as, 3D-printed satellites, space-suits, and zero gravity experiments etc. which are also very recent interest of NASA. Furthermore, a detailed comparative analysis between a full-wave model and a 3D-printed prototype of the antenna is also presented here. The antenna dimensions have been optimized for an operating frequency of 2.56 GHz in S-band (2 – 4 GHz) for suitable in-space applications.","PeriodicalId":180982,"journal":{"name":"2021 United States National Committee of URSI National Radio Science Meeting (USNC-URSI NRSM)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121557160","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 simulated bandwidths of transmit and receive operations are 1260 MHz and 810 MHz, respectively. The simulated results show good isolation, S21, reaching −60 dB at the center frequency. The design also maintains peak realized gain from 6.7 dB to 7.6 dB through the entire band of interest.
