## Abstract

Disclosed is a vehicular antenna, which includes an antenna module having an antenna patch, a reflector installed to be spaced apart from the antenna patch by a predetermined distance to maximize a gain of an electromagnetic wave radiated from the antenna patch at a specific angle, and a dielectric substance inserted and installed between the antenna patch and the reflector.

## Claims

### Claim 1

A vehicular antenna, comprising:
an antenna module having an antenna patch;
a reflector installed to be spaced apart from the antenna patch by a predetermined distance to maximize a gain of an electromagnetic wave radiated from the antenna patch at a specific angle; and
a first dielectric substance inserted and installed between the antenna patch and the reflector,
wherein the antenna module includes:
a ground surface:
a second dielectric substance laminated on the ground surface;
and the antenna patch laminated on the second dielectric substance;
wherein an upper surface of the reflector has a fractal structure.

### Claim 2 (depends on 1)

The vehicular antenna according to claim 1, wherein the first dielectric substance is installed in contact with the reflector and spaced apart from the antenna patch by a predetermined distance.

### Claim 3 (depends on 2)

The vehicular antenna according to claim 2, further comprising:
a spacer installed in a space between the antenna patch and the first dielectric substance to be in contact with the antenna patch and the first dielectric substance.

### Claim 4 (depends on 3)

The vehicular antenna according to claim 3, wherein the spacer is a sponge.

### Claim 5 (depends on 1)

The vehicular antenna according to claim 1, wherein the first dielectric substance has a dielectric permittivity of 3 to 50.

### Claim 6 (depends on 5)

The vehicular antenna according to claim 5, wherein the dielectric permittivity of the first dielectric substance is 12.

### Claim 7 (depends on 6)

The vehicular antenna according to claim 6, wherein the first dielectric substance and the reflector have a size identical to or greater than the antenna patch.

### Claim 8 (depends on 6)

The vehicular antenna according to claim 6, wherein the first dielectric substance has a greater thickness than the reflector.

### Claim 9 (depends on 6)

The vehicular antenna according to claim 6, wherein a distance between the first dielectric substance and the antenna patch is 0.1 mm.

### Claim 10 (depends on 6)

The vehicular antenna according to claim 6, wherein a distance between the reflector and the antenna patch is 1.2 mm.
