Dual-band antenna
First Claim
1. A dual-band antenna disposed on a substrate for transceiving electromagnetic signals of different frequencies, comprising:
- a grounded portion;
a feeding portion adjacent to the grounded portion, for feeding signals; and
a radiation body electronically connected to the feeding portion, comprising;
a first radiation portion, comprising a first free end, a first connecting end electronically connected to the feeding portion, and a serpentine portion between the first free end and the first connecting end; and
a second radiation portion, comprising a second connecting end electronically connected to the first connecting end, and a second free end, wherein the first free end and the second free end face each other and a gap is formed therebetween;
wherein the first radiation portion and the second radiation portion collectively define a hole at a center of the radiation body, two opposite circumambient sides of the hole extending straightly while the rest circumambient sides of the hole extending curvilinearly.

Abstract
A dual-band antenna (10) is disposed on a substrate (20), for transceiving electromagnetic signals of different frequencies. The dual-band antenna includes a grounded portion (12), a feeding portion (14), and a radiation body (16). The feeding portion is adjacent to the grounded portion. The radiation body electronically connected to the feeding portion, includes a first radiation portion (160) and a second radiation portion (162). The first radiation portion includes a first free end (160c), a first connecting end (160a) electronically connected to the feeding portion, and a serpentine portion (160b) between the first free end and the first connecting end. The second radiation portion, includes a second connecting end (162a) electronically connected to the first connecting end, and a second free end (162b), wherein the first free end and the second free end face each other and a gap (18) is formed therebetween.
