In this paper, an experimental investigation of ADM-based microstrip square patch antenna with unique characteristic in resonant frequency lowering is presented. The ADM is implemented by configuring cylindrical-shaped copper conductors in such a way in a dielectric substrate, i.e. styrofoam, as host material which is perpendicular to the antenna patch and the groundplane. To show potentiality of the unique characteristic, a similar construction of conventional microstrip square patch antenna realized using a styrofoam is also experimentally characterized as comparison. The characterization result indicates that the use of ADM has affected the resonant frequency lowering up to 13.1% from the conventional antenna.","PeriodicalId":230714,"journal":{"name":"2020 International Workshop on Antenna Technology (iWAT)","volume":"29 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":"123722724","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 this paper, analytical comparison of two power weighted functions, i.e. Blackman and Kaiser, is investigated for linear array antennas with small number of elements. Some linear array antennas with small odd and even number of elements are used to implement the weighting coefficient based on Blackman and Kaiser functions at the X-band frequency of 9.5GHz. The use of both functions is intended to have some expected radiation characteristic in terms of width of mainlobe (WML) and sidelobe level (SLL). The analysis result shows that Blackman function with small number of elements could achieve the radiation characteristics with predefined SLL of 68.8dB and inter element spacing of $lambda$/1.5, but with some WML enhancement. This performance is better in SLL suppression than Kaiser function with predefined SLL of 68.8dB and $beta$ of 6.623.","PeriodicalId":230714,"journal":{"name":"2020 International Workshop on Antenna Technology (iWAT)","volume":"37 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":"125092041","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}
