Notes: --- - Article - "The development of a non-conventional (NC) LTCC glass-ceramic composite using a unique \xE2\x80\x98quench free glass\xE2\x80\x99, and subsequent realization of a patch antenna on this substrate, are reported. This novel composition is comprised of Sr2ZnTeO6 (SZT) and 5 wt% of ZBPT (10 mol% ZnO \xE2\x80\x93 2 mol% B2O3 \xE2\x80\x93 8 mol% P2O5 \xE2\x80\x93 80 mol% TeO2) glass where the latter reaction mixture can be added directly to the ceramic, bypassing the high temperature melt quenching step. The average particle size distribution shows a more uniform and narrow distribution of powder prepared through non-conventional approach, compared to the conventional approach (C) where the quenched glass powder was added to the ceramic. The sintered tapes show \xCE\xB5r values of 11.64 and 12.12 for both SZT + ZBPT (C) and SZT + ZBPT (NC) respectively. The breakdown strength of both sintered tapes comes > 1100 V/2 mil. The SZT + ZBPT (NC) tape show lower leakage current and better resistivity (5.3 \xC3\x97 108 \xCE\xA9\xC2\xB7cm) compared to SZT + ZBPT (C) (2.9 \xC3\x97 108 \xCE\xA9\xC2\xB7cm). In order to check the feasibility of developed LTCC tape as microwave substrates, a prototype of ceramic patch antenna operating at 2.5 GHz was designed and printed on sintered LTCC tapes of SZT + ZBPT (NC) and its radiation characteristics were analyzed and discussed. \xC2\xA9 2017 Elsevier Ltd" - "Export Date: 12 January 2018" - "Funding details: Council for Scientific and Industrial Research"
