Fig. 1 is the schematic diagram of the mobile communications device of an one exemplary embodiment of the present invention.With reference to Fig. 1, mobile communications device 100 includes substrate 110, metal edge frame 120, feeding portion 130, Parasitica 140, support member 150 and transceiver 160.Wherein, the first surface of substrate 110 is provided with ground plane 111, and the region being not provided with ground plane 111 on the first surface of substrate 110 will be regarded as empty regions 112.That is, from another angle, substrate 110 includes ground plane 111 and empty regions 112.
Feeding portion 130 and Parasitica 140 are positioned at empty regions 112, and are positioned in different planes from ground plane 111.In other words, on entity configures, feeding portion 130 and Parasitica 140 are projected in the relative position on substrate 110, with ground plane 111 non-overlapping copies.For example, as it is shown in figure 1, in a preferred embodiment, support member 150 is arranged in empty regions 112, and includes first surface 151 and second surface 152.Wherein, first surface 151 is parallel to ground plane 111, and second surface 152 is perpendicular to ground plane 111.Additionally, feeding portion 130 is arranged on the first surface 151 of support member 150, and Parasitica 140 is arranged on first surface 151 and the second surface 152 of support member 150.
Metal edge frame 120 is looped around the surrounding of substrate 110, and includes two clearance G P11 and clearance G P12.Additionally, metal edge frame 120 forms the first edge frame members 121 and the second edge frame members 122 being separated from each other by two clearance G P11 and clearance G P12.Wherein, the first edge frame members 121 is electrically connected to ground plane 111.For example, in Fig. 1 embodiment, the first edge frame members 121 is electrically connected to ground plane 111 by multiple electric-conductors 171～174.Wherein, electric-conductor 171～174 can be for example any element with electric conductivity such as shell fragment or screw.In other words, the first edge frame members 121 has the multiple earth point P11～P14 being connected to ground plane 111.
Furthermore, with regard to the second edge frame members 122, it is then electrically connected to Parasitica 140.For example, in Fig. 1 embodiment, empty regions 112 is positioned at a corner of substrate 110, and the second edge frame members 122 is relative to the support member 150 being arranged in empty regions 112.Additionally, the first end of the second edge frame members 122 is directly or indirectly electrically connected to the first end of Parasitica 140.Such as, in Fig. 1 embodiment, the first end of the second edge frame members 122 is indirectly to be electrically connected to Parasitica 140 by electric-conductor 175.Additionally, the second end of the second edge frame members 122 is open circuit.Further to seeing, the second end of Parasitica 140 is electrically connected to ground plane 111.Additionally, the first end of feeding portion 130 is relative to clearance G P11 and in order to receive a FD feed, and the second end of feeding portion 130 is open circuit.
Operationally, transceiver 160 can pass through a coaxial line (not shown) provides FD feed to the first end of feeding portion 130, and then causes mobile communications device 100 can form a loop aerial (loopantenna) 10 by feeding portion the 130, second edge frame members 122 and Parasitica 140.In other words, metal edge frame 120 not only improves the appearance design of mobile communications device 100, and the metal edge frame 120 of part (that is, the second edge frame members 122) can also be used with to use as antenna.Therefore, the impact that the metal edge frame 120 communication quality on mobile communications device 100 causes can will be reduced.In addition, metal edge frame 120 cannot also be electrically connected to ground plane 111 as the first edge frame members 121 that antenna uses, and then be more conducive to promote the communication quality of mobile communications device 100.
Furthermore, by the loop aerial 10 that feeding portion the 130, second edge frame members 122 and Parasitica 140 are formed, also have the characteristic of multi-band operation.For example, when the first termination of feeding portion 130 receives FD feed, feeding portion 130 transmits signals to the second edge frame members 122 also by the mode of coupling, and then causes loop aerial 10 to inspire multiple resonance mode.Such as, loop aerial 10 can pass through feeding portion 130 and inspire the first resonance mode, to receive or to launch the first radiofrequency signal being positioned at GSM1800/1900/UMTS frequency band.Additionally, loop aerial 10 inspires the second resonance mode also by the second edge frame members 122 with Parasitica 140, to receive or to launch the second radiofrequency signal being positioned at GSM850/900 frequency band.
In entity structure, the length of feeding portion 130 is 1/4 times of the wavelength of the first radiofrequency signal.Additionally, from the second end of the second edge frame members 122 along the second edge frame members 122 and Parasitica 140, extend to 1/4 times of the wavelength that path is the second radiofrequency signal of the second end of Parasitica 140.Noticeable, although Fig. 1 embodiment lists the implementation type of loop aerial 10 but it is not limited to the present invention.
For example, Fig. 2 is the schematic diagram of the mobile communications device of another one exemplary embodiment of the present invention.Wherein, being differing primarily in of Fig. 1 and Fig. 2 two embodiment, the loop aerial 10-1 in Fig. 2 also includes adjustment portion 210.
In specific words, in Fig. 2 embodiment, adjustment portion 210 and feeding portion 130 are the first surfaces 151 at support member 150 set along.Additionally, on being electrically connected, first end in adjustment portion 210 is directly or indirectly electrically connected to the second end of the second edge frame members 122.Such as, in Fig. 1 embodiment, first end in adjustment portion 210 is the second end being indirectly electrically connected to the second edge frame members 122 by electric-conductor 220.Additionally, second end in adjustment portion 210 is open circuit.Therefore, mobile communications device 200 can form loop aerial 10-1 by feeding portion 130, adjustment portion the 210, second edge frame members 122 with Parasitica 140.
Additionally, operationally, when the first termination of feeding portion 130 receives FD feed, feeding portion 130 transmits signals to adjustment portion 210 also by the mode of coupling, and then causes loop aerial 10-1 to inspire multiple resonance mode.Such as, loop aerial 10-1 can pass through feeding portion 130 and inspire the first resonance mode, to receive or to launch the first radiofrequency signal being positioned at GSM1800/1900/UMTS frequency band.Additionally, loop aerial 10-1 inspires the second resonance mode also by adjustment portion the 210, second edge frame members 122 and Parasitica 140, to receive or to launch the second radiofrequency signal being positioned at GSM850/900 frequency band.For example, Fig. 3 be the loop aerial of an one exemplary embodiment of the present invention return loss (returnloss) simulate schematic diagram.As it is shown on figure 3, loop aerial 10-1 can inspire the second resonance mode meeting GSM850/900 frequency band, and the first radiofrequency signal meeting GSM1800/1900/UMTS frequency band can be inspired.
It should be noted that with Fig. 1 embodiment similarly, first resonance mode of loop aerial 10-1 is formed by feeding portion 130.Therefore, with regard to entity structure, in loop aerial 10-1, the length of feeding portion 130 is also 1/4 times of the wavelength of the first radiofrequency signal.Additionally, with Fig. 1 embodiment the difference is that, the loop aerial 10-1 in Fig. 2 is except forming the second resonance mode by the second edge frame members 122 with Parasitica 140, it forms the second resonance mode also by adjustment portion 210.Therefore, with regard to entity structure, from second end in adjustment portion 210 along adjustment portion the 210, second edge frame members 122 and Parasitica 140, extend to 1/4 times of the wavelength that path is the second radiofrequency signal of the second end of Parasitica 140.
In other words, in the design of the second resonance mode, those skilled in the art can pass through the addition in adjustment portion 210, reaches path and meets the design requirement of 1/4 wavelength.In addition, those skilled in the art also can according to design, by changing the shape in adjustment portion 210 or/and Parasitica 140, extend the length of adjustment portion 210 or/and Parasitica 140, and then cause the path of adjustment portion the 210, second edge frame members 122 and Parasitica 140 to meet the design requirement of 1/4 wavelength.For example, the Parasitica 140 cited by Fig. 2 be shaped as strip.But, in another one exemplary embodiment, the shape of Parasitica 140 also can be for example curve-like.In other words, in another one exemplary embodiment, Parasitica 140 has bending structure, and mobile communications device 200 can pass through the bending structure of Parasitica 140, causes the path of adjustment portion the 210, second edge frame members 122 and Parasitica 140 to meet the design requirement of 1/4 wavelength.Similarly, in another one exemplary embodiment, the Adjusting Shape in adjustment portion 210 also can be become curve-like by those skilled in the art, and therefore reaches path and meet the design requirement of 1/4 wavelength.
In sum, embodiments of the invention are the appearance designs utilizing metal edge frame to promote mobile communications device, and utilize the metal edge frame (that is, the second edge frame members) of part to form antenna.Therefore, the impact that the metal edge frame communication quality on mobile communications device causes can will be reduced.In addition, metal edge frame cannot also be electrically connected to ground plane as the first edge frame members that antenna uses, and then be more conducive to promote the communication quality of mobile communications device.
