2. Description of the Related Art

FIG. 1 shows a cross-sectional view of the antenna structure according to the prior art. The antenna structure includes a PCB 1a, and an antenna module 2a connected to the PCB 1a. The antenna module 2a has an antenna contact 20a inserted into and electrically connected to the PCB 1a. The antenna contact 20a has a bottom side 200a projected out the PCB 1a. A heatproof twin adhesive 3a attaches the antenna module 2a on the PCB 1a.

However, the prior art has some defects, as follows:

(1) The heatproof twin adhesive 3a attaches the antenna module 2a to the PCB 1a, so the antenna structure is not conveniently assembled;

(2) The heatproof twin adhesive 3a attaches the antenna module 2a to the PCB 1a, so it is not convenient to use the twin adhesive 3a. Therefore, the quality of the antenna structure is not stable, and the price of the antenna structure is not good;

(3) The bottom side 200a of the antenna contact 20a is projected out the PCB 1a, so the bottom side of the PCB 1a is not level; and

(4) Noise interference occurs between the antenna module 2a and the PCB 1a.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to FIGS. 2 and 3, the first embodiment of the present invention provides an antenna structure including a PCB 1 with a plurality of contacts, a metal support element 2, and an antenna module 3.

The metal support element 2 is metal covered support, and has a support portion 20 formed therearound. The support portion 20 is fixed on the PCB 1 by SMT (Surface Mounted Technology) or inserted solder technology. The antenna module 3 is a GPS (Global Positioning System). The antenna module 3 is connected on the metal support element 2 by an adhesive body (not shown). The antenna module 3 has an antenna contact 30 that passes through a through hole 22 of the metal support element 2 and is inserted into a corresponding through hole 12 of the PCB 1. The adhesive body is a ceramics adhesive or a heatproof adhesive.

Referring to the FIGS. 4 and 5, the antenna contact 30 of the antenna module 3 has a bottom side 300. The metal support element 2 is used to support the antenna module 3 for the bottom side 300 of the contact 30 to be embedded in the through hole 12 of the PCB 1. In other words, the antenna contact 30 of the antenna module 3 is electrically connected to the PCB 1, and does not project out of the through hole 12 on a bottom side of the PCB 1. Therefore, the bottom side of the PCB 1 is level.

The metal support element 2 is used to shield the noise interference between the PCB 1 and the antenna module 3 for increasing the security of the antenna module 3 in use.

The FIGS. 6 and 7 show the second embodiment of the present invention. The support portion 20 of the metal support element 2 is a plurality of pins extended downwardly therefrom. The present invention does not limit the number of the pins and the distance between the two pins. The metal support element 2 has a contact surface smaller or larger than that of the antenna module 3. The metal support element 2 has different shapes according to the designer for the antenna module 3.

The FIGS. 8 and 9 show the third embodiment of the present invention. The PCB 1 has a plurality of pins 10 disposed on a bottom portion thereof.

The PCB 1 and the support element 2 are joined together to form a circuit module 4 by low-temperature cofired technology. The circuit module 4 and the antenna module 3 are assembled together to form an antenna module with a circuit function. The PCB 1 is fixed on the support portion 20 of the support element 2 by the pins 10. Moreover, the antenna structure is filled with good heat-conducting material between the PCB 1 and the support element 2.

To sum up, the antenna structure of the present invention includes some advantages, as follow:

(1) The support portion 20 of the support element 2 is fixed on the PCB 1 by SMT or inserted solder technology for increasing the convenience to assemble the antenna structure;

(2) When the antenna module 3 connects to the PCB 1, the antenna contact 30 of the antenna module 3 passes into the through opening 42 and does not project out the bottom side of the PCB 1. Hence, the bottom side of the PCB 1 is level; and

(3) The support element 2 is arranged between the PCB 1 and the antenna module 3 for shielding the noise interference between the antenna module 3 and the PCB 1, and increasing the sensitivity of the antenna module 3 in use.

Although the present invention has been described with reference to the preferred embodiment thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and modification have suggested in the foregoing description, and other will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
