We designed, fabricated, and evaluated a monopole water antenna (WA) filled with pure water. A 2.4 GHz patch antenna (PA) was used for measurement comparison, and the current density distribution and 3D field strength radiation distribution and reflection coefficient of the PA had a fundamental mode and a higher-order mode at 3.5 GHz, whose polarization was 90 degrees different. The 2.4 GHz monopole...
This paper proposes procedures for categorizing group opinions and making preference order of them, in circumstances of group decision-making. First, a fuzzy opinion matrix is constructed, in which each element is derived from the difference between two evaluation vectors. The difference of the two is well expressed by the symmetric evaluation method based on sigmoid function and tangent function...
