Definitions
- the present invention is related to a communication device antenna utilizing a metal housing for emitting and receiving radio signals of a communication device according to the pre-characterizing clause of claim 1.
- plastic housings are mainly used by manufacturers due to cost concerns, in order to maintain basic radiation characteristics of an antenna.
- metal housing is currently brought by Apple iPhones and Macbooks. Since the metal housing has light weight, good heat dissipation, high strength, high impact resistance, good looking, anti-electromagnetic and recyclable characteristics, the metal housing is getting more and more popular. Therefore, the metal housings are mainly used in development of new generations of the mobile communication products.
- US patent No. 8,054,231 B2 disclosed by Ahn et al. teaches a metal case having a slot, which can be used as a slot antenna of a mobile device.
- the slot may obviously ruin appearance of the metal case, and the slot needs to be arranged at a position corresponding to a specific area of the metal case. Therefore, it is important to design a proper antenna to allow electromagnetic waves to penetrate the metal case for achieving communication purposes without obviously ruining the appearance of the metal case.
- the present invention aims at providing a communication device antenna utilizing a metal housing for emitting and receiving radio signals of a communication device.
- the claimed communication device antenna comprises a metal housing, a first antenna, a signal feed point, a ground point and a second antenna.
- the metal housing has a first lateral side and a second lateral side corresponding to the first lateral side.
- the first antenna comprises a first metal part, a second metal part, a third metal part and a fourth metal part.
- the third metal part is extended and connected between the first metal part and the second metal part, and the third metal part is located adjacent to the first lateral side of the metal housing.
- the fourth metal part is connected to the metal housing.
- the second antenna comprises a first metal part, a second metal part and a third metal part.
- the first metal part of the second antenna is connected to the signal feed point and the second metal part of the first antenna.
- the second metal part of the second antenna is connected to the ground point and the fourth metal part of the first antenna.
- the third metal part of the second antenna is extended and connected between the first metal part and the second metal part of the second antenna.
- a slit is formed and located between the metal housing and the first antenna.
- FIG. 1 and FIG. 2 are diagrams showing a communication device 10 having a metal housing 12 according to an embodiment of the present invention.
- the metal housing 12 has a first lateral side 14a, and a second lateral side 14b located at a position corresponding to the first lateral side 14a.
- Antenna arrangement of the communication device 10 comprises a first antenna 16 and a second antenna 18.
- the first antenna 16 comprises a first metal part 20, a second metal part 22, a third metal part 24 and a fourth metal part 26.
- the first metal part 20 is a straight section
- the second metal part 22 is also a straight section
- the first metal part 20 is longer than the second metal part 22.
- the third metal part 24 is extended and connected between the first metal part 20 and the second metal part 22. In a preferred embodiment, the third metal part 24 is located adjacent to the first lateral side 14a of the metal housing 12.
- the fourth metal part 26 is connected to the second lateral side 14b of the metal housing 12.
- the first metal part 20, the second metal part 22, the third metal part 24 and the fourth metal part 26 together define an antenna trace.
- a slit 15 is formed and located between the metal housing 12 and the first antenna 16, such that the first antenna 16 is not short-circuited.
- the slit 15 is not limited by a shape and arrangement disclosed in the embodiment of the present invention.
- a printed circuit board 30 is further arranged in the communication device 10.
- the printed circuit board 30 comprises a signal feed point 32 and a ground point 34.
- the second antenna 18 comprises a first metal part 36, a second metal part 38 and a third metal part 40 extended and connected between the first metal part 36 and the second metal part 38.
- first metal part 36 is located between the first metal part 20 and the second metal part 22 of the first antenna 16
- second metal part 38 is located between the first metal part 20 and the fourth metal part 26 of the first antenna 16.
- the first metal part 36 is connected to the signal feed point 32 and the second metal part 22 of the first antenna 16.
- the second metal part 38 is connected to the ground point 34 and the fourth metal part 26 of the first antenna 16.
- the first antenna 16 is configured to work as a larger loop antenna, which is applicable to a first frequency; and the second antenna 18 is configured to work as a smaller loop antenna, which is applicable to a second frequency. Therefore, when the communication device 10 is turned on to provide power to the first antenna 16 and the second antenna 18 via the signal feed point 32 and the ground point 34, the metal housing can work as a radiation unit, for transmitting and receiving radio signals of the communication device 10.
