Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a metal base high efficiency antenna, particularly to an ceramic antenna monomer can be provided onto a connector of an electronic appliance, such that the connector has functions of antenna, and the signal transmission of antenna would not be interfered by the metal material inside the electronic appliance.

2. Description of the Related Art

A conventional electronic appliance must be provided with an antenna to achieve wireless receiving or wireless communication. Generally, the antenna is formed directly on a circuit board of the electronic appliance, or as a rod-like body, which is inserted from the outside of the electronic appliance and then connected to a ground terminal of the circuit board on the electronic appliance for signal transmission.

As shown in FIG. 1, in a conventional electronic appliance 1A, an end of a circuit board (not shown) is provided with a ground terminal 1C. An external antenna 1B is connected to the ground terminal 1C through a transmission line 1D, providing the electronic appliance 1A with functions of wireless signal transmission.

However, with the increasing diversity of devices in various types of electronic appliances, not only the slim and compact design is required, but also a number of metallic elements (e.g. metal enclosure) are provided to products to enhance product quality. In response to the antenna efficiency, a circuit board would leave a space for the antenna as a clearance area, but this design would result in poor utilization efficiency of a product's motherboard. Moreover, as a result of the design of electronic appliance towards miniaturization, there is less and less clearance area for an internal antenna, further limiting functions of the antenna. Thus, most antennas only have single-frequency operation capabilities. However, as the market is getting mature and increased, if the antenna being provided only has a single-frequency operation capability, its operational capacity and market competitiveness would be significantly inadequate. Additionally, to maintain the appearance and quality of the product, the antenna would be limited to a certain space. All these may result in the circumstance that the appearance and antenna efficiency could not be taken into account at the same time.

SUMMARY OF THE INVENTION

Accordingly, it is an objective of the present invention to provide a metal base high efficiency antenna, which is served as a ceramic antenna monomer integrally joined with a connector, such that the connector is equipped with the antenna function.

According to the metal base high efficiency antenna of the present invention, since said connector is mostly provided at the outer surface of an electronic appliance, a ceramic antenna monomer integrally joined with the connector can avoid interference from metallic elements of electronic appliances, which affects signal transmission. This is another objective of the present invention.

According to the metal base high efficiency antenna of the present invention, the ceramic antenna monomer is produced by low temperature cofired ceramic, and is constituted as a particle fine piece, such that it can be easily provided on any metallic elements of electronic appliances to provide the metallic elements with the antenna function. This is another objective of the present invention.

According to the metal base high efficiency antenna of the present invention, the ceramic antenna monomer may be installed to the connector, such that the connector has the signal emission and transmission capability due to the mounting of the antenna body. The internal space of the electronic appliance can be planned more effectively because there is no need to additionally design space for an antenna. This is another objective of the present invention.

According to the metal base high efficiency antenna of the present invention, the ceramic antenna monomer may also integrally joined with an electronic communication interface such as a HDMI (High Definition Multimedia Interface) connector, USB (Universal Serial Bus), or Com Port (Communication Port), such that the electronic communication interface such as HDMI connector, USB, or Com Port has the signal emission and transmission capability. This is a further objective of the present invention.

According to the metal base high efficiency antenna of the present invention, when the ceramic antenna monomer integrally joined with an electronic communication interface such as a connector or a HDMI connector, since the electronic communication interface such as the HDMI connector, USB, or Com Port is usually arranged at a space near the outer surface of the electronic appliance, as the antenna is integrated with the element, the element surface can be used for radiation. Therefore, the signal transmission efficiency can be significantly enhanced. This is a further objective of the present invention.

The objective, shape, configuration means, characteristics and effects of the present invention will be apparent with reference to the following description in conjunction with the accompanying drawings.
