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 above-mentioned various electronic equipments, and the type of electronic equipment is not construed as limiting the invention.
Antenna assembly 100 according to the embodiment of the present invention comprises: the first antenna element 110, has the first Department of Radiation 111, for transmitting the first aerial signal of the first frequency range; Second antenna element 120, has the second Department of Radiation 121, and for transmitting the second aerial signal of the second frequency range, this second frequency range is different from the first frequency range; Detecting unit 130, for detecting the operating state of the second antenna element; Switch unit 140, for described first Department of Radiation being couple to the second antenna element when described operating state is in particular case, utilizes described first Department of Radiation to transmit the second aerial signal to make described second antenna element.
Described first antenna element 110 and the second antenna element 120 can be the antennas utilizing any technology to realize, such as microstrip antenna, unipole antenna, loop aerial, telescopic antenna etc.Concrete antenna type is not construed as limiting the invention.One of described first frequency range and the second frequency range can be each different communications bands.Hereinafter, for the first frequency range be FM signal frequency range (76MHz-108MHz), the second frequency range is that GSM frequency range (890MHz-954MHz) is described.
First antenna element 110 has the first Department of Radiation 111 and transmits the first aerial signal, and the frequency of this first aerial signal is in the first frequency range.This first Department of Radiation 111 can be used to the second antenna element 120 under specific circumstances to transmit the aerial signal of the second frequency range.Exemplarily, the physical dimension of this first Department of Radiation 111 can change, such as its physical dimension can switch between the first physical dimension and the second physical dimension, thus when the first Department of Radiation 111 is used to transmission the first aerial signal, there is the first physical dimension, there is when being used to transmission the second aerial signal the second physical dimension.Such as, when the first antenna element 110 is telescopic antenna, this first Department of Radiation 111 can be the pull bar in telescopic antenna, now, first physical dimension of described first Department of Radiation 111 can be included in this telescopic antenna for transmitting the first length during the first aerial signal, and the second physical dimension of this first Department of Radiation 111 can be included in this pull bar for transmitting the second length during the second aerial signal.In practice, the length of single-unit or the joint number of pull bar by changing pull bar obtain required physical dimension.When the first frequency range described above be the low-frequency range of such as FM signal frequency range, the second frequency range be the high band of such as GSM frequency range, the first length as the pull bar of the first Department of Radiation 111 is greater than its second length.
Along with the change of the type of the first antenna element 110, the change method for the first Department of Radiation 111 transmitting aerial signal in the first antenna element 110 also can change.Such as, when the first antenna element 110 is the unipole antenna comprising different radiation branch, carrys out optionally radiation by making the different forked workings of unipole antenna and receive the first aerial signal of described first frequency range or the second aerial signal of the second frequency range.
