In this paper, we present the considerations on miniaturizing the size of the circular disc antennas, which are often used in UWB applications. Quarter circular disc antenna has been proposed to ...

In this paper, a new vertical half disc-loaded monopole antenna (VHDMA) with a horizontally top-loaded small disc is investigated. This antenna provides a similar radiation pattern compared to that of ...

But they have the same membership functions of symmetrical triangle. The inference logic of MAX-MIN method is employed in two fuzzy controllers, similarly the defuzzification method of centroid ...
