The modeling and analysis of the DoA detection scheme prove that it is possible to improve the measurement accuracy by increasing the inter-element distance between the receiving antennas. The proposed scheme is suitable for use at 5G millimeter wave frequencies as the wavelength is less than one centimeter and many antennas could be easily integrated within the receiver.","PeriodicalId":128207,"journal":{"name":"2018 18th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128697200","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 employed multi-port waveguide structure is manufactured using brass material to achieve an excellent electrical conductivity and high corrosion resistance. The performances of direct conversion receiver based on the fabricated multi-port structure are experimentally demonstrated in terms of various M-ary PSK modulated signals (BPSK, QPSK, 8PSK, and 16 PSK) through a reliable test bench setup. The obtained results demonstrate the ability of the proposed multi-port receiver to accurately handle low-power input signals, while performing various direct M-ary PSK demodulation at 60 GHz millimeter-wave band. Moreover, the robustness, the higher corrosion and wear resistance of the fabricated multi-port structure make it a highly suitable for use in challenging outdoor environments, such as future V-band inter-building wireless links.","PeriodicalId":128207,"journal":{"name":"2018 18th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132319320","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}

Typically, the deposition of a $VO_{2}$ switch utilizes complex fabrication processes which result in higher costs. The ideal approach would be to use low-cost additive manufacturing techniques, such as screen printing. This work presents a novel fully screen-printed frequency reconfigurable PIFA / T-shaped monopole antenna with a printed $VO_{2}$ switch. The switch operates through thermal activation and reconfigures the frequency band. The antenna operates at 2.7 GHz band or at 3.5 GHz band for two different operational modes of the $VO_{2}$ switch.

Then the pulse is temporally expanded up to 500 fs using a prism pair stretcher at 900 nm and the n2 is measured.
