At 2.45 GHz, the direction of current is forward
moving nature on the L4 element and L3 element. In other
words the current in L4 element is moving in right side
direction. More clearly, in the L3 element, the current is
moving upward and in the L2 element, the current is moving
left side direction. Hence in the element L2 and L4, the
current is moving in opposite direction. At the corner junction
of element L3 and width we, the current is moving in
the same direction and a current addition situation arises
which is shown in Fig 7(a). Similarly at 5.2 GHz, the current
in the L1 element is moving downward. But in the Lc
element, the movement and direction of current are very
much peculiar to watch. At the top of the Lc element, the
current is moving forward, but at the left hand corner i.e. at
the width we, the current is reflected backward and creating
