a opposition to the upward moving current in Lk element
along with the reflected current from the L1 element. Hence
at Lk element, the current from both the direction met each
other and a cancellation situation arises which is depicted
in Fig 7(b). In Fig. 7 the black arrows are the overall direction
of the current in the entire 9-shaped radiating element.
As known, the electromagnetic coupling effect controlled
the two excited resonant frequencies at 2.45 GHz and
5.2 GHz between the (Lc+Lk) element and (L1+Lk) element.
