## Abstract

A glazing unit extends along a plane, P, defined by a longitudinal axis, X, and a vertical axis, Z; having a width, W, measured along the longitudinal axis, X, and a length, L, measured along the vertical axis, Z, and includes at least a glass panel and an antenna unit. The antenna unit includes an antenna. The antenna unit also includes a fixing portion for fixing the antenna to the glass panel so that a space, S, through which air can flow is formed between the glass panel and the antenna. At least one non-fixing portion and at least one metallic element are placed over at least a part of the non-fixing portion of the antenna unit.

## Claims

### Claim 1

A glazing unit extending along a plane, P, defined by a longitudinal axis, X, and a vertical axis Z; having a width, W, measured along the longitudinal axis, X, and a length, L, measured along the vertical axis, Z, comprising:
a glass panel; and
an antenna unit,
wherein the antenna unit comprises:
an antenna;
a fixing portion for fixing the antenna to the glass panel so that a space through which air can flow is formed between the glass panel and the antenna;
at least one non-fixing portion which is a portion of the antenna unit not in contact with the glass panel; and
at least one metallic element placed over at least a part of the non-fixing portion of the antenna unit, and
wherein the at least one metallic element further comprises at least one hole corresponding with the space of the antenna unit such that air can flow through the at least one hole from the space to outside of the antenna unit.

### Claim 2 (depends on 1)

The glazing unit according to claim 1, wherein the antenna unit comprises two non-fixing portions and wherein the at least one metallic element is placed over at least a part of at least one of the non-fixing portions.

### Claim 3 (depends on 2)

The glazing unit according to claim 2, wherein the antenna unit comprises first and second metallic elements, the first metallic element is placed over at least a part of one of the non-fixing portions and the antenna unit and the second metallic element is placed over at least a part of the second non-fixing portion of the antenna unit.

### Claim 4 (depends on 1)

The glazing unit according to claim 1, wherein the at least one metallic element further comprises a meshed portion corresponding with the space of the antenna unit.

### Claim 5 (depends on 1)

The glazing unit according to claim 1, wherein a largest dimension of the at least one hole of the at least one metallic element is at most 0.4 times an effective wavelength.

### Claim 6 (depends on 1)

The glazing unit according to claim 1, wherein a largest dimension of every hole of the at least one metallic element further is at most 0.4 times an effective wavelength.

### Claim 7 (depends on 1)

The glazing unit according to claim 1, wherein a largest dimension of every hole of every metallic element further is at most 0.4 times an effective wavelength.

### Claim 8 (depends on 1)

The glazing unit according to claim 1, wherein the glass panel comprises at least one glass sheet.

### Claim 9 (depends on 8)

The glazing unit according to claim 8, wherein the glass panel comprises two glass sheets separated by a spacer.

### Claim 10 (depends on 1)

The glazing unit according to claim 1, wherein the at least one metallic element covers the at least one non-fixing portion and the antenna at least near the at least one non-fixing portion.

### Claim 11 (depends on 1)

The glazing unit according to claim 1, wherein the at least one metallic element covers the fixing portion.

### Claim 12 (depends on 1)

The glazing unit according to claim 1, wherein the glass panel is at least partially covered by a coating system.

### Claim 13 (depends on 12)

The glazing unit according to claim 12, wherein the coating system has an opening in front of the antenna unit.

### Claim 14 (depends on 1)

The glazing unit according to claim 1, wherein the glass panel is separated from the antenna unit at a distance of 20 mm to 50 mm in plan view.
