Claim 10:
11. An antenna apparatus of an electronic device and comprising:
a ground plane; and
a plurality of antenna elements disposed on the ground plane, wherein each of the antenna elements comprises:
one exciting element or the one exciting element and M parasitic elements, wherein M is a non-negative integer, wherein the one exciting element comprises:
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 one exciting element to the first side is L1;
a second side opposite to the first side, wherein a distance from the one 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 one exciting element to the third side is p1, wherein the seventh end is proximate to the third side; and
a fourth side that is opposite to the third side, wherein a distance from an eighth end of the one exciting element to the fourth side is p2, wherein the eighth end is proximate to the fourth side, and wherein a difference between p1 and p2 is less than a first value;

a feeding port disposed on the one exciting element;
a first slot disposed on the first branch 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, and
wherein, when M is not equal to zero, each of the M parasitic elements is coupled with the ground plane, wherein a distance from each of the M parasitic elements to the first side is L3, wherein a distance from each of the M parasitic elements to the second side is L4, and wherein L3 is less than L4,
wherein p1 is equal to p2.
