Multi-band antenna
First Claim
1. An antenna, comprising:
- a first radiating portion having a first end portion and a second end portion opposite to the first end portion;
a second radiating portion extending from the first end portion and toward the second end of the first radiating portion;
a gap formed between the first radiating portion and the second radiating portion, which comprises;
an opening slot formed between the first radiating portion and the second radiating portion; and
a connecting slot and an end slot formed in the second radiating portion, a width of the connecting slot being wider than a width of the opening slot.

Abstract
A multi-band antenna includes a first radiator resonating at a high frequency bans and a second radiator extended from a first end and toward a second end of the first radiator, and resonating at a low frequency range. An opening slot is formed between the first and the second radiators. A connecting slot and an end slot are formed in the second radiator. The width of the connecting slot is wider than the width of the opening slot. The connecting slot can prevent vectors potential caused by the second radiator from being neutralized. The electromagnetic coupling effect over the opening slot caused by the first radiator and the second radiator can pull down the low frequency range for reducing the size of the second radiator. Therefore, the multi-band antenna has a small size.
