Abstract

An antenna module includes a radiation unit, a ground unit and an electrostatic protection unit. The radiation unit includes a metal element and a substrate. The metal element is disposed on a surface of the substrate. The ground unit is disposed on another surface of the substrate. The electrostatic protection unit is disposed in the substrate and connected between the metal element and the ground unit.

Claims

1. An antenna module, comprising:

a radiation unit including a metal element and a substrate, wherein the metal element is disposed on a surface of the substrate;

a ground unit disposed on another surface of the substrate;

an electrostatic protection unit disposed in the substrate and connected between the metal element and the ground unit; and

an electrical conduction element disposed in the substrate, wherein the electrical conduction element and the electrostatic protection unit form a series connection between the metal element and the ground unit.

2. The antenna module recited in claim 1, wherein the electrical conduction element is connected with the ground unit and the electrostatic protection unit is connected with the metal element.

3. The antenna module recited in claim 1, wherein the electrical conduction element is connected with the metal element and the electrostatic protection unit is connected with the ground unit.

4. The antenna module recited in claim 1, wherein the electrostatic protection unit and the electrical conduction element are disposed in an area formed by a projection of the metal element on the substrate.

5. The antenna module recited in claim 1, wherein the electrostatic protection unit and the electrical conduction element are embedded in the substrate.

6. The antenna module recited in claim 1, wherein the material of the electrical conduction element includes copper, silver, aluminum, zinc, gold or any alloy thereof.

7. The antenna module recited in claim 1, wherein the electrostatic protection unit is a voltage dependent resistor.
