Embodiment
In order to more clearly state the present invention, below in conjunction with accompanying drawing, the present invention is further described.
Refer to Fig. 1, radio-television integral receive antenna provided by the invention, comprise radio reception helical antenna oscillator 1, magnetic core 2, a pair spiral television antenna oscillator 3, connecting screw 5 and plastic cement inner core 4; Surperficial one end of plastic cement inner core 4 is smooth, and there is the groove holding thin cylindrical conductor centre, and middle part has helicla flute, and the other end has the step of accommodating magnetic core 2; Radio reception helical antenna oscillator 1 comprises helical form conductive part 11 and buttress shaft shape conductive part 12, the buttress shaft shape conductive part 12 of radio reception helical antenna oscillator 1 inserts the groove inside of the thin cylindrical conductor of accommodation of plastic cement inner core 4, the helical form conductive part 11 of radio reception helical antenna oscillator 1 is tight around on the helicla flute of plastic cement inner core 4, magnetic core 2 is circular, and the step being sheathed on plastic cement inner core 4 is clamped between helical form conductive part 11 and this step; A pair spiral television antenna oscillator 3 is wrapped in the smooth ends of plastic cement inner core 4 symmetrically.
Compared to the situation of prior art, radio-television integral receive antenna provided by the invention, the helical groove portion of the stage portion of accommodating magnetic core and the helical form conductive part of accommodating radio reception helical antenna oscillator is set on the surface of plastic cement inner core, and the smooth ends of accommodating a pair spiral television antenna oscillator 3, make antenna structure simply compact, thus realize reception signals reception and radio TV signals receiving integration; In addition, the present invention arranges core structure further, to strengthen antenna sensitivity and to widen the bandwidth of antenna.
In the present embodiment, above-mentioned radio-television integral receive antenna also comprises connecting screw 5, connecting screw 5 is fixedly connected with plastic cement inner core 4, connecting screw 5 has the first electrical connection section and the second electrical connection section, first electrical connection section of connecting screw 5 is electrically connected with the buttress shaft shape conductive part of radio reception helical antenna oscillator 1, and the second electrical connection section of connecting screw 5 is electrically connected with a pair spiral television antenna oscillator 3.
In the present embodiment, above-mentioned radio-television integral receive antenna also comprises plastic jacket 6, plastic jacket 6 is fixedly connected with connecting screw 5 and encloses a cavity, and radio reception helical antenna oscillator 1, magnetic core 2, a pair spiral television antenna oscillator 3 and plastic cement inner core 4 are placed in this cavity.
The present invention has following characteristics:
