Embodiment
As Fig. 1-shown in Figure 5, the Active Receiving Antenna device is moved in amusement of the present utility model, form by radome 1, installation base plate 4 and FM, AM antenna 2 and setting FM/AM amplifying circuit mainboard 3 in the circuit board, the same pressure source that described amplifying circuit connects the mobile vehicle receiving equipment provides radio frequency powered, and FM antenna and FM/AM amplifying circuit mainboard 3 are designed to an integral body; FM antenna and wiring board 3 all are fixed on the installation base plate 4 in the radome 1.The FM antenna be distributed in mainboard 3 following, the right, above; The AM antenna 2 outer AM signal input parts that are connected on the FM/AM circuit main board; The FM/AM circuit main board is installed in above the base plate by screw 5 levels; The AM antenna is fixed on the top of radome 1 by glue; FM/AM circuit main board 3 is of a size of 37.7*31.2mm, and the employing dielectric constant is 3.5 epoxy plate; The bottom of mainboard 3 is connected with cable 6, and there is joint 7 cable 6 ends.
Described device is installed on the top of mobile vehicle, is fixed on the set of mobile vehicle top by nut and is equipped with on the antenna installing hole, and the hole that output passes whole device base plate is connected on the receiving equipment of mobile vehicle.Two amplifier tubes that amplifying circuit adopted of described AM, FM are respectively 9018 and UPC1651G.
The utility model is that the Active Receiving Antenna device is moved in a kind of amusement, in order to allow two signal not disturb mutually, utilize 9018 and the signal finished separately of the amplifier tube of two high s/n ratios of UPC1651G amplify.Because the frequency of AM frequency range is lower, and system volume less, so antenna can only be designed to screw type magnetic rod antenna.The FM antenna is the version of printed substrate, and the design of antenna is carried out further and optimized, and antenna is distributed on three different directions of circuit main board (following, the right, top), has overcome the blind area of received signal better.The work of FM/AM amplifying circuit is to provide radio frequency powered by the automobile receiving equipment, and the direct-current working volts that obtain 5V through voltage-stabiliser tube 78L05 promote amplifier tube work.After antenna receives signal, the AM signal through 9018, the FM signal is through UPC1651G, separately signal is amplified, thereby reaches separately specification requirement (the AM:525-1605KHz 15Db that gains; FM:87-108MHz gain: 25dB).
