## Abstract

An antenna structure includes a portable electronic apparatus and an antenna. The portable electronic apparatus includes a housing. At least a metal block is arranged at a corner of the housing. The antenna is arranged in an accommodating space of the housing. The antenna includes a radiator. The radiator includes a rear end and a signal feed-in contact. A distance between the rear end, the signal feed-in contact, and the metal block is about one-fourth wavelength of communication signals, wherein the rear end faces the metal block. Therefore, the SAR of the antenna is reduced.

## Claims

### Claim 1

An antenna structure including:
a portable electronic apparatus having a housing and at lease a metal block, the metal block arranged in the housing, the housing including an accommodating space; and
an antenna arranged in the accommodating space, the antenna including a radiator, the radiator including an open end and a signal feed-in contact,
wherein the open end of the antenna faces the metal block; an electric current path from the signal feed-in contact to the metal block is one-fourth wavelength of communication signals.

### Claim 2 (depends on 1)

The antenna structure in claim 1, wherein the accommodating space includes a plurality of corners; the metal block is arranged at the corner.

### Claim 3 (depends on 2)

The antenna structure in claim 2, wherein the accommodating space includes an installation area for arranging the antenna.

### Claim 4 (depends on 3)

The antenna structure in claim 3, wherein the metal block is arranged at the corner of the accommodating space; the antenna is near the corner.

### Claim 5 (depends on 4)

The antenna structure in claim 4, wherein the radiator includes a plurality of metal lines.

### Claim 6 (depends on 5)

The antenna structure in claim 5, wherein the radiator includes a rear end; the rear end is the open end of the radiator.

### Claim 7 (depends on 6)

The antenna structure in claim 6, wherein the radiator further includes a front end.

### Claim 8 (depends on 7)

The antenna structure in claim 7, wherein the radiator further includes a grounding body electrically connected to the front end of the radiator.
