Multi-band antenna structure
First Claim
1. A multi-band antenna structure for use in a telecommunication device comprising:
- a ground plane; and
a plurality of radiating elements comprising;
a first radiating element including a first radiating portion disposed beside the ground plane, and a first connecting portion connecting the first radiating portion with the ground plane;
a second radiating element including a second radiating portion disposed beside the first radiating portion, forming a first resonance slot therebetween, and a second connecting portion connecting the second radiating portion with the ground plane, wherein the second radiating portion further includes a feed-point for electrically connecting to a signal feed cable, the feed point being located adjacent to the second connecting portion;
a third radiating element including a third radiating portion disposed above the second radiating portion, and a third connecting portion connecting the third radiating portion with the second radiating portion;
a fourth radiating element including a fourth radiating portion disposed beside the third radiating portion, forming a second resonance slot therebetween, and a fourth connecting portion connecting the fourth radiating portion with the second radiating portion; and
a fifth radiating element including a fifth radiating portion disposed above the third radiating portion, forming a third resonance slot therebetween, and a fifth connecting portion connecting the fifth radiating portion with the second radiating portion.

Abstract
A multi-band antenna structure (1) includes a ground plane (10) and a plurality of radiating elements (11, 12, 13, 14, 15). Each radiating element has a radiating portion and a connecting portion connected with the corresponding radiating portion. The first and second connecting portions (111, 121) are respectively connected to the ground plane, and a first resonance slot (21) is formed between the first and second radiating portions (110, 120). The third, fourth, and fifth connecting portions (131, 141, 151) are respectively connected to the second radiating portion. A second resonance slot (22) is formed between the third and fourth radiating portion (130, 140), and a third resonance slot (23) is formed between the third and fifth radiating portion (130, 150).
