Guarantee its mobility and portability for making, above-mentioned mobile communication terminal (MS) miniaturization is day by day made, and the technical development that has benefited from continuing and the variation gradually of its function.
In above-mentioned mobile communication terminal (MS), its time of generally in communication, using short and be communicate standby or time of carrying longer, for making the convenience that improves the lower utilization rate of above-mentioned mobile communication terminal (MS) and use, continually develop out multiple value-added service recently at mobile communication terminal.
The value-added service of above-mentioned mobile communication terminal (MS) is the service that provides except basic voice communication service, wherein, the service that the mobile communication service provider exploitation provides has: for example, wireless Internet (WIRELESSINTERNET) connects, short message transmits, Multimedia Message transmits, wireless online is played (WIRELESSONLINE GAME) etc.; The service that mobile communication terminal manufacturer (MAKER) exploitation provides has: for example, and telephone directory book (PHONE-BOOK) management, bluetooth (BLUETOOTH), infrared ray (IRDA), alarm clock, ringtone setting, message making, recreation, camera, calculator etc.Along with the development of mobile communication technology, above-mentioned value-added service continues exploitation provides new function.
Value-added service as above-mentioned mobile communication terminal (MS), develop data broadcasting and radio (RADIO) broadcasting recently, move reception TV (TV, TELEVISION) DMB of broadcast singal (DMB, DIGITAL MULTIMEDIA BROADCASTING) function.
Above-mentioned DMB (DMB) has the surface wave DMB (TDMB of the broadcast singal of reception ground (TERRESTRIAL) transmission, TERRESTRIAL DMB) digital multimedia broadcast (dmb) via satellite (SDMB, the SATELLITE DMB) mode of the broadcast singal of mode and reception artificial satellite (SATELLITE) transmission.In the present invention, as an embodiment surface wave DMB (TDMB) is described.
For making mobile communication terminal receive above-mentioned digital multimedia broadcasting signal, need respectively be provided with above-mentioned tracking exchage antenna and DMB antenna for receiving, and, for making portability and the mobility of guaranteeing mobile communication terminal, need develop and to use the antenna that receives and have shorter length at mobile communication and DMB jointly.
Above-mentioned surface wave DMB (TDMB) is the broadcasting that the frequency band that will provide is cut apart according to code division multiple access (CDMA) mode and broadcasted the voice-grade signal with digital form, and it is provided with the television channel that comprises radio channel, be used to broadcast multimedia level signal, be used to broadcast about about 60 channel of the data channel of data-signal.
There is different places in each channel of above-mentioned DMB (DMB) in terms of content according to its characteristic, and for example, the product that broadcast the channel of roundup news, the channel that broadcasts sports content, the channel that broadcasts the fishing content, broadcast mountain-climbing content are large quantities of.The channel etc. that broadcasts the channel of music content, the channel that broadcasts entertainment, the channel that broadcasts the program of acting in a play, the channel that broadcasts the religion content, general merchandise product channel, the channel that broadcasts general breeding content, broadcast education content has multiple play content, except above-mentioned each content (CONTENTS), also be provided with the channel that different operators provides.
The bandwidth (BANDWIDTH) of distributing in the surface wave DMB (TDMB) of an above-mentioned embodiment is 175.264 to 214.736KHz, therefore, will use with as about 195MHz of above-mentioned bandwidth intermediate frequency antenna as the length scale of reference design.

But, in the mobile communication terminal of guaranteeing its mobility and portability, the antenna (ANTENNA) that need develop the shorter length of a kind of use also can receive the antenna of surface wave DMB (TDMB) signal and mobile communication signal simultaneously with higher antenna gain.
Antenna assembly to the digital multimedia broadcast mobile communication terminal in an embodiment of the prior art describes with reference to the accompanying drawings.
Fig. 1 is the functional structure chart of general surface wave digital multimedia broadcasting system; Fig. 2 is the contour structures state description figure of digital multimedia broadcast mobile communication terminal of the prior art; Fig. 3 is the configuration state key diagram of compound antenna of the prior art.
Embodiment below with reference to above-mentioned accompanying drawing 1 describes general surface wave digital multimedia broadcasting system, DMB radio station 40 includes corresponding contents DMB (DMB) signal of a plurality of channels (CH) of television broadcasting signal by ground (TERRESTRIAL) broadcasting (BROADCASTING), and the signal that broadcast in above-mentioned DMB radio station 40 will be respectively receives with wireless mode by home terminal (TV) 30 that receives with stationary state in the vehicle termination 10 that is provided with in the vehicle or mobile communication terminal (MS) 20, the family.
As an example, the broadcasting with variant content object is broadcasted in above-mentioned surface wave DMB radio station 40 by 60 channels.
Above-mentioned mobile communication terminal 20 has when using as mobile communication, also can move whenever and wherever possible and receive the advantage of TV (TV) broadcast singal, but respectively be provided with the antenna that is used for mobile communication simultaneously and be used to receive the antenna of surface wave DMB (TDMB) signal with wireless mode.
The bandwidth (BANDWIDTH) of distributing in the above-mentioned surface wave DMB (TDMB) is 175.264 to 214.736KHz, therefore, to use with as about 195MHz of above-mentioned bandwidth intermediate frequency antenna as the length scale of reference design, the antenna wavelength that needs under the condition of above-mentioned 195MHz (λ) length is about 150 centimetres (Cm).
Above-mentioned antenna uses in long (λ), the half-wavelength (λ/2) of all-wave, 1/4 wavelength (1/4 λ) the length antenna, above-mentioned surface wave DMB (TDMB) need be provided with about 38 centimetres (Cm) or 354 millimeters (mm) antenna to 400 millimeters (mm) length under the situation of using whiplike (WHIP TYPE) λ/4 antennas.
According to an aforesaid embodiment, receive under the situation of antenna that surface wave DMB (TDMB) uses λ/4 wavelength length for making, the antenna of about 38 centimetre lengths need be set, its be main for portable and mobility and the mobile communication terminal of miniaturization making length oversize.
Contour structures state below with reference to 2 pairs of digital multimedia broadcast mobile communication terminals of the prior art of above-mentioned accompanying drawing describes.As shown in the figure, respectively be provided with in the above-mentioned digital multimedia broadcast mobile communication terminal 20: the antenna 22 of about 38 centimetres of (Cm) length that is used to receive λ/4 wavelength of surface wave digital multimedia broadcasting signal; Be used to receive the mobile communication frequency signal and the antenna 24 of wavelength selected length.
As mentioned above, respectively be provided with the antenna that is used for mobile communication in the above-mentioned surface wave digital multimedia mobile communication terminal 20) 24 and be used to receive the antenna 22 of surface wave DMB (TDMB), make on contour structures comparatively complicated.
