Claim 0:
1. An antenna apparatus of an electronic device and comprising:
a ground plane; and
an exciting element comprising:
a first branch, wherein a first gap is disposed between the first branch and the ground plane, and wherein the first branch comprises:
a first end; and
a second end; and

second branches coupling the first branch to the ground plane, wherein the second branches comprise:
a third branch comprising a third end coupled to the first end and a fourth end coupled to the ground plane; and
a fourth branch comprising a fifth end coupled to the second end and a sixth end coupled to the ground plane,

wherein the ground plane comprises:
a first side, wherein a distance from the exciting element to the first side is L1;
a second side opposite to the first side, wherein a distance from the exciting element to the second side is L2, and wherein L1 is less than L2;
a third side, wherein a distance from a seventh end of the exciting element to the third side is p1, wherein the seventh end is proximate to the third side; and
a fourth side opposite to the third side, wherein a distance from an eighth end of the exciting element to the fourth side is p2, wherein a difference between p1 and p2 is less than a first value, and wherein, the eighth end is proximate to the fourth side;
a feeding port disposed on the exciting element;
a first slot disposed on the first branch and defining two parts of the first branch on two sides of the first slot; and
a first capacitor coupled in series between the two parts of the first branch,
wherein p1 is equal to p2.
