## Abstract

Disclosed is an antenna device for transceiving a wireless signal. The antenna device includes an antenna element adapted to establish a radiation pattern during transceiving the wireless signal; an antenna signal feeding line coupling to the antenna element for feeding the wireless signals transceived by the antenna element; and at least one radiation pattern adjustment element arranged at an adjacent position with respect to the antenna element and within the established radiation pattern of the antenna element to adjust the radiation pattern of the antenna element.

## Claims

### Claim 1

An antenna device for transceiving a wireless signal, comprising:
a longitudinally extended antenna element adapted to establish a radiation pattern during transceiving the wireless signal;
an antenna signal feeding line coupled to the antenna element for feeding the wireless signals transceived by the antenna element; and
at least one longitudinally extended radiation pattern adjustment element, consisting of magnetic material and being arranged at an adjacent position with respect to the antenna element and within the established radiation pattern of the antenna element, the at least one longitudinally extended radiation pattern adjustment element being displaced in a longitudinally direction of the antenna element to adjust the radiation pattern of the antenna element.

### Claim 2 (depends on 1)

The antenna device as claimed in claim 1, wherein the antenna signal feeding line is directly connected to the antenna element.

### Claim 3 (depends on 1)

The antenna device as claimed in claim 1, wherein the antenna element is an omni-directional antenna adapted to establish an omni-directional radiation pattern.

### Claim 4 (depends on 1)

The antenna device as claimed in claim 1, wherein the antenna element is a directional antenna adapted to establish a directional radiation pattern comprising at least one stronger radiation pattern area and at least one weaker radiation pattern area.

### Claim 5 (depends on 4)

The antenna device as claimed in claim 4, wherein the radiation pattern adjustment element is arranged at a position within the stronger radiation pattern area.

### Claim 6 (depends on 4)

The antenna device as claimed in claim 4, wherein the radiation pattern adjustment element is arranged at a position within the weaker radiation pattern area.

### Claim 7 (depends on 1)

The antenna device as claimed in claim 1, wherein the radiation pattern adjustment element is located above the antenna element.

### Claim 8 (depends on 1)

The antenna device as claimed in claim 1, wherein the radiation pattern adjustment element is located below the antenna element.

### Claim 9 (depends on 1)

The antenna device as claimed in claim 1, wherein the radiation pattern adjustment element is located in side-by-side relationship with respect to the antenna element.
