Specifically, a circularly polarized UHF RFID reader antenna conformal to a dielectrically controlled plastic support is proposed. The radiating element has been realized through a circular array of four inverted-F monopoles, where the array elements are excited with a 90-degree phase offset (sequential rotation feeding technique) through a microstrip feeding network. To allow for a friendly prototype realization, the antenna structure is thought to be shaped on adhesive copper and the dielectric support to be 3D-printed in Poly-Lactic Acid (PLA), opportunely selected due to interesting low losses properties. The very compact antenna (60mm x 60mm x 6.5mm), suitable for the desired portable Reader, has been characterized in terms of reflection coefficient, port isolation and radiation patterns.","PeriodicalId":230714,"journal":{"name":"2020 International Workshop on Antenna Technology (iWAT)","volume":"445 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116020678","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 designed antenna has a low profile of 17 – 31.5 – 0.127 mm3 constructed from an elliptic patch surrounding by another elliptic ring printed on RT/duroid substrate, fed by an edge-feed transmission line and a proper partial ground plane. The reconfigurable performance is achieved by inserting two PIN diodes, one between the patch and the feed line and the other in the gap of the elliptic ring. By changing the states of the PIN diode, the antenna bandwidth characteristics change resulting in three operating modes including UWB, band-pass, and band-reject antenna performance. In each operating state, the antenna performance has been examined in terms of S-parameter, maximum gain, radiation efficiency, and radiation pattern characteristics using CST Studio Suite 3-D EM software.","PeriodicalId":230714,"journal":{"name":"2020 International Workshop on Antenna Technology (iWAT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128441277","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}

Starting from realistic antenna specifications, the trade-offs between antenna architecture complexity, phase-control resolution over the radiating aperture, aperture efficiency, side lobe levels, and beam scanning performance are discussed at the antenna system level and evaluated through numerical simulations. Two designs of linearly-polarized 2-bit reconfigurable unit-cells controlled by four p-i-n diodes are proposed for downlink and uplink bands. By opportunely combining orthogonally-polarized designs based on the proposed cells, two transmitarrays achieving switchable circular polarization and fulfilling the targeted specifications are presented.","PeriodicalId":230714,"journal":{"name":"2020 International Workshop on Antenna Technology (iWAT)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128537386","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}

One of essential benefits applying circularly polarized array antenna is the capability in minimizing the Faraday effect. The proposed array antenna consists of 5 microstrip square patch elements designed on 2 layers of FR4 dielectric substrate with 0.8mm thick of each layer. Each square patch element with multiple rectangular-slots to achieve circular polarization is fed by using proximity coupling technique to improve the radiation characteristics. Some investigations upon the geometry of array antenna as well as its feeding lines are carried out through simulation to gain an optimum architecture design implemented for hardware realization. The characterization results show the realized array antenna with the dimension of 119mm $times$ 44.1mm could achieve the gain more than 6dBi around the frequency of 5GHz with the 3dB axial ratio bandwidth of 262MHz.","PeriodicalId":230714,"journal":{"name":"2020 International Workshop on Antenna Technology (iWAT)","volume":"178 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121491188","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}
