Embodiment
Hereinafter with reference to relevant drawings, a kind of radio communication device according to the preferred embodiment of the present invention is described, wherein identical assembly will be illustrated with identical element numbers.
Please refer to shown in Figure 2ly, it is the partial cross section figure of the preferred embodiment of radio communication device of the present invention.Radio communication device comprises a housing 20, an antenna element 22 and a protective layer 24, and this antenna element 22 is set directly at the outer surface 201 of housing 20.
Referring again to shown in Figure 3, it is the partial cross section figure of another preferred embodiment of radio communication device of the present invention.In this radio communication device, also comprise a housing 20 and an antenna element 22, and antenna element 22 is to utilize metallic conductor 28 to electrically connect with the circuit board 26 that is arranged in the housing 20, yet, the antenna element 22 that is different from the radio communication device that is among Fig. 3 to be disclosed of above-mentioned enforcement aspect is not to be arranged on the outer surface 201 of housing 20 and the inner surface 202 that is arranged on housing 20, therefore need not offer any hole on housing 20.In addition, the electrical interference on antenna element 22 and the circuit board 26 between other electronic building brick, the outer surface of antenna element 22 can be by protective mulch 24 with as completely cutting off or the usefulness of protection.
Though the outer surface of antenna element 22 shown in Figure 3 is coated with protective layer 24; but because antenna element 22 is arranged on the inner surface 202 of housing 20; therefore; also can be directly by direct contact of housing 20 with the obstruct antenna element 22 and the external world; and do not make antenna element 22 be subjected to oxidation or damage easily, also, when antenna unit 22 is arranged at the inner surface 202 of housing 20; can be according to the specification and the demand of different product, protective mulch 24 on the outer surface of antenna element 22 optionally.
Radio communication device can be mobile phone (cellular phone), personal digital assistant (personal digitalassistant, PDA), palmtop computer (handheld PC), global positioning system or wireless headset.Antenna element 22 can be the metallic paint antenna, and antenna element 22 be formed at the outer surface 201 of housing 20 or inner surface 202 method can by spray paint, mode such as baking vanish, screen painting, coating, plating, evaporation or sputter.Antenna element 22 of the present invention only need housing 20 spray paint or baking vanish before form the metallic paint antenna earlier in the outer surface 201 or the inner surface 202 of housing 20, need not to change existing technology.
In addition, the laying kenel of antenna element 22 then can be designed different shapes according to design specification with the demand of different product.For the enforcement aspect that antenna element 22 is formed on housing 20 outer surfaces 201, because antenna element 22 is formed on the outer surface 201 of housing 20, signal transmitting and receiving need not to penetrate housing 20, signal strength signal intensity is unlikely influenced by housing 20 and decays or distortion, therefore can strengthen the usefulness of radio communication device receiving and transmitting signal.
In addition, because antenna element 22 is formed at the outer surface 201 or the inner surface 202 of housing 20, but not circuit board 26, thereby only need keep the zone of a load point 261 on the circuit board 26, so significantly reduce the required area of circuit layout on the circuit board 26, also and the size that can dwindle circuit board 26.Perhaps, circuit board 26 can life size and the zone that will vacate as the setting area of other electronic building brick, to increase the functional of radio communication device.Than the known antenna that is arranged on the circuit board, antenna element 22 of the present invention can not be subjected to the obstruct of housing 20 and influence the transmission of signal, and does not have the problem of reception directivity, also promptly helps the usefulness of radio communication device receiving and transmitting signal.
In sum, according to a kind of radio communication device of the present invention, because antenna element is arranged at housing but not circuit board, so can save the area of circuit layout on the circuit board, also can will originally be used for being provided with other electronic building brick, to increase the functional of radio communication device in order to the zone that antenna element is set.Compare with known technology, the present invention need not to change structural design or changes technology, and the area of housing provides bigger antenna element to lay the space, and can strengthen the usefulness of radio communication device receiving and transmitting signal.In addition, the present invention can simplify the making and the assembling of antenna element, shortens assembling man-hour and saves cost.
The above only is an illustrative, but not is restrictive.Anyly do not break away from spirit of the present invention and category, and, all should be contained in the accompanying Claim scope its equivalent modifications of carrying out or change.
