Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.In various embodiments of the present invention, use identical Reference numeral to mark the same unit institute parts in antenna assembly.
In the present invention, when be described to discrete cell between first component and second component time, can intervening elements be there is between this particular elements and first component or second component, also can not there is intervening elements; When being described to particular elements and connecting other parts, this particular elements directly can be connected with other parts described and not have intervening elements, also directly can not be connected with other parts described and have intervening elements.
Fig. 1 is the block diagram of the antenna assembly 100 schematically illustrated according to the embodiment of the present invention.This antenna assembly 100 can be applicable to any electronic equipment, includes but not limited to computer, personal digital assistant, mobile communication terminal, audiovisual players etc.The type of the electronic equipment that antenna assembly 100 is applied to is not construed as limiting the invention.
As shown in Figure 1, this antenna assembly 100 comprises: the first Department of Radiation 110, has spiral-shaped, and for transmitting the first aerial signal, the frequency of this first aerial signal is in the first frequency range; Second Department of Radiation 120, for being positioned at the linear conductor at the center of described spiral, for transmitting the second aerial signal, the frequency of this second aerial signal is in the second frequency range, and the frequency of this second frequency range is higher than the frequency of described first frequency range; Linkage unit 130, for being electrically connected to described first Department of Radiation by described second Department of Radiation; Feed end 140, is positioned on one of described first Department of Radiation and second Department of Radiation, with at described first Department of Radiation and feed antenna signal between the second Department of Radiation and described aerial signal transceiver.
Described first Department of Radiation 110 is spiral-shaped conductors, and for transmitting the first aerial signal, the frequency of this first aerial signal is in the first frequency range.The radiation direction of described first Department of Radiation 110 is relevant with the circumference of helix.When the circumference of helix less than wavelength a lot of time, the strongest direction of radiation is perpendicular to helical axis; When helix circumference is the order of magnitude of a wavelength, most intense radiation appears on spiral rotary direction of principal axis.The frequency of the first aerial signal that the first Department of Radiation 110 transmits is corresponding with at least one in the length of described first Department of Radiation and helix pitch.Correspondingly, in practice, desired antenna frequencies is obtained by the spacing of the conductor of adjustable screw shape or the number of turn etc. of spiral.In addition, along with the first Department of Radiation 110 helix between spacing reduce, the radiation efficiency of antenna also can correspondingly reduce, and therefore, consider the size and the structure that design the first Department of Radiation 110.
In FIG, the spiral of the first Department of Radiation 110 is circular, and this is only example, and it can also be square or its shape can adjust according to the space reserved for antenna.Usually, in order to improve the radiance of described first Department of Radiation 110, the end of electronic equipment can be placed on, correspondingly can arrange described first Department of Radiation 110 in conjunction with the appearance design in electronic equipment.In addition, the communication frequency of antenna is higher, then the space shared by antenna is less; The communication frequency of antenna is lower, then the space shared by antenna is larger.When electronic equipment is mobile phone, first frequency range of described first Department of Radiation 110 may be used for transmitting global positioning system (GPS, Global Positioning System) signal, the communication frequency of gps signal is such as 1575.42 ± 3MHz, this first frequency range can also be used for Digital Cellular System (DCS, the Digital Cellular System) signal transmitting 1800MHz.
Described second Department of Radiation 120 is for being positioned at the linear conductor at the center of described spiral.Because described first Department of Radiation 110 has spiral-shaped, so have space at the center of spiral.Antenna assembly according to the embodiment of the present invention reasonably utilizes this spiral space, insert the second Department of Radiation 120 at the center of described spiral and carry out radiation second aerial signal, thus this second Department of Radiation 120 transmits aerial signal with the described first shared space of Department of Radiation 110, and do not take special space, thus save the space hold of antenna.
Second Department of Radiation 120 transmit the second aerial signal frequency be in the second frequency range.As previously mentioned, the communication frequency of antenna is higher, then the space shared by antenna is less.If the frequency of this second frequency range is higher than the frequency of described first frequency range, then it takies less antenna space for the first Department of Radiation 110, thus may utilize the spiral space of the first Department of Radiation 110 when not affecting the antenna performance of the first Department of Radiation 110.Exemplarily, this second frequency range is for transmitting the WiFi signal on 2.4GHz and at least one in Bluetooth signal.When use second Department of Radiation 120 transmits both WiFi signal and Bluetooth signal simultaneously, further expand the function of antenna.
The frequency of described second aerial signal can be corresponding with at least one in the relative position of the first Department of Radiation 110 with the length of described second Department of Radiation 120 and its.Due to the first Department of Radiation 110 and the second Department of Radiation 120 common antenna space, therefore influencing each other of the two always exists, such as, the second aerial signal occurrence frequency skew that the first aerial signal that the first Department of Radiation 110 transmits may cause the second Department of Radiation 120 to transmit.In an embodiment of the present invention, consider influencing each other between the first Department of Radiation 110 and the second Department of Radiation 120 when designing, and utilize this to influence each other to regulate the antenna parameter of the second Department of Radiation 120 on one's own initiative, thus improve the design flexibility of antenna.Similarly, the antenna parameter influencing each other to regulate the first Department of Radiation 110 between the first Department of Radiation 110 and the second Department of Radiation 120 can also be utilized.
