Abstract

Presented is a UWB antenna module configured to implement omni-directional characteristics with respect to bearings even when mounted on a metal ground plane. The presented UWB antenna module comprises: a base sheet; a radiation pattern formed on a front surface of the base sheet; and a ground pattern formed on the front surface of the base sheet and arranged to surround the radiation pattern.

First claim

The invention claimed is:

1. A UWB antenna module comprising:
a base sheet;
a radiation pattern formed on a front surface of the base sheet;
a ground pattern formed on the front surface of the base sheet and disposed to surround the radiation pattern; and
a radiation sheet disposed in a rear surface of the base sheet to cover the entire rear surface of the base sheet, and overlaps with the radiation pattern and the ground pattern.

2. The UWB antenna module of claim 1 ,
wherein the radiation pattern comprises:
a first radiation pattern of a square frame shape;
a second radiation pattern disposed to be spaced apart from the first radiation pattern; and
a third radiation pattern connecting the first radiation pattern to the second radiation pattern.

3. The UWB antenna module of claim 2 ,
wherein the ground pattern is disposed to surround three sides adjacent to the first radiation pattern.

4. The UWB antenna module of claim 2 ,
wherein the third radiation pattern is connected to one side of four sides of a virtual square region formed by the first radiation pattern that is not surrounded by the ground pattern.

5. The UWB antenna module of claim 2 ,
wherein the first radiation pattern comprises:
a first side;
a second side having one end connected to one end of the first side;
a third side having one end connected to the other end of the first side; and
a fourth side having one end connected to the other end of the second side and the other end connected to the other end of the third side.

6. The UWB antenna module of claim 5 ,
wherein the ground pattern comprises:
a first ground pattern spaced apart from the first side of the first radiation pattern and disposed parallel to the first side;
a second ground pattern connected to the one end of the first ground pattern and disposed parallel to the second side of the first radiation pattern; and
a third ground pattern disposed to face the second ground pattern with the first radiation pattern interposed therebetween, connected to the other end of the first ground pattern, spaced apart from the third side of the first radiation pattern, and disposed parallel to the third side.

7. The UWB antenna module of claim 5 ,
wherein the one end of the third radiation pattern is connected to the fourth side of the first radiation pattern, and the other end of the third radiation pattern is connected to the second radiation pattern.

8. The UWB antenna module of claim 1 ,
wherein the radiation sheet is disposed to cover the entire rear surface of the base sheet.

9. The UWB antenna module of claim 1 , further comprising: another radiation pattern disposed on at least one surface of the front and rear surfaces of the base sheet.

10. The UWB antenna module of claim 1 , further comprising: a magnetic sheet disposed on a rear surface of the base sheet,
wherein the magnetic sheet is disposed to cover a region of the rear surface of the base sheet excluding a region in which the radiation sheet is disposed.
