Built-in antenna module in portable wireless terminal
Disclosed is a built-in antenna module for a portable wireless terminal, in which an antenna carrier allows a distance between a radiator and a mainboard. In the built-in antenna module, the antenna carrier includes a plate type junction panel to which the radiator is fixed, an outer barrier rib extending along an edge of the junction panel with a uniform height, and at least one compartment barrier rib for dividing a space formed by the junction panel and the outer barrier rib. The antenna carrier accommodates a speaker and a vibrator at the space formed by junction panel and the outer barrier rib, such that additional installation spaces for the speaker and the vibrator are not required and thereby the portable wireless terminal comes to be slim, lightweight, and simple.
1. A built-in antenna module for a portable wireless terminal, comprising an antenna carrier to allow a distance between a radiator and a mainboard, the antenna carrier including:
a plate type junction panel to which the radiator is fixed;
an outer barrier rib extending along an edge of the junction panel; and
at least one compartment barrier rib for dividing a space formed by the junction panel and the outer barrier rib,
wherein the space accommodates at least one of a vibrator and a speaker, and is closed with a cover after the accommodation.
2. The built-in antenna module of claim 1 , wherein the height of the outer barrier rib is selected such that the distance between the radiator and the mainboard is sufficiently large to improve the radiation characteristic of the antenna and reduce the Specific Absorbtion Rate and to accommodate a speaker and vibrator.
3. The built-in antenna module of claim 2 , wherein the space divided by the compartment barrier rib accommodates the speaker and the vibrator separately.
4. The built-in antenna module of claim 3 , wherein the outer rib defines a wave hole about the space where the speaker is accommodated in order to pass speaker sound therethrough.
5. A built-in antenna module for a portable wireless terminal, comprising:
a mainboard;
an antenna carrier assembly mounted on the mainboard;
an antenna radiator installed on the antenna carrier assembly and electrically connected with an RF (Radio frequency) connector;
at least one accommodation space formed inside the antenna carrier assembly, the at least one accommodation space accommodating a combination speaker/vibrator module; and
a plate type cover for closing the at least one accommodation space after the accommodation of the combination sneaker/vibrator module.
6. The built-in antenna module of claim 5 , wherein a vibration motor employed to the combination speaker/vibrator module is a brushless motor.
7. The built-in antenna module of claim 5 , wherein the antenna carrier assembly includes:
an antenna carrier having a plate type junction panel on which the antenna radiator is installed and an outer barrier rib downwardly extended along an edge of the junction panel with a uniform height to define a downwardly opened space,
wherein the plate type cover having a bottom faced with the mainboard, the plate type cover being coupled to the downwardly opened space in overlapping relationship with the outer barrier rib to define the accommodation space in which the combination speaker/vibrator module is accommodated.
8. The built-in antenna module of claim 7 , wherein a vibration motor employed to the combination speaker/vibrator module is a brushless motor.
9. The built-in antenna module of claim 5 , wherein the plate type cover includes:
an installation hole having a predetermined diameter to partially expose the combination speaker/vibrator module; and
an upwardly protruded portion with a predetermined shape around the hole to tightly enclose some portion of the circumference of the combination speaker/vibrator module.
10. The built-in antenna module of claim 9 , wherein a vibration motor employed to the combination speaker/vibrator module is a brushless motor.
11. The built-in antenna module of claim 5 , wherein the plate type cover includes a leg barrier rib downwardly extended along an edge to prevent the bottom of the plate type cover from direct face-contact with the mainboard when the antenna carrier assembly is installed on the mainboard.
12. The built-in antenna module of claim 11 , wherein a vibration motor employed to the combination speaker/vibrator module is a brushless motor.
13. The built-in antenna module of claim 11 , wherein the combination speaker/vibrator module installed inside of the antenna carrier assembly is spaced a predetermined distance apart from the antenna radiator in a vertical direction.
14. The built-in antenna module of claim 13 , wherein a vibration motor employed to the combination speaker/vibrator module is a brushless motor.
15. The built-in antenna module of claim 13 , wherein the predetermined distance is at least 2.3 mm.
16. The built-in antenna module of claim 15 , wherein a vibration motor employed to the combination speaker/vibrator module is a brushless motor.
