It is given to the speaker 8 and driven to obtain a voice output.
ところで、このような比較的短いロッドアンテナ等で中
波帯の電波を受信すると、電波の波長に対してアンテナ
の長さが極めて短いために、共振アンテナとはならず容
量性アンテナとして動作すると考えられる。このため、
アンテナに誘起された電圧は、アンテナの容量と給電線
の容量とに分圧されるので受信機のアンテナ端子におけ
る入力レベルは著しく減少され、効率が悪く、受信感度
が劣化する。By the way, when a medium-wave radio wave is received by such a relatively short rod antenna, it is considered that the antenna does not function as a resonant antenna but operates as a capacitive antenna because the length of the antenna is extremely short with respect to the wavelength of the radio wave. Be done. For this reason,
Since the voltage induced in the antenna is divided into the capacitance of the antenna and the capacitance of the feeder line, the input level at the antenna terminal of the receiver is significantly reduced, the efficiency is poor and the receiving sensitivity is deteriorated.
［発明の目的］ 本発明は上記の事情に鑑みてなされたもので、アンテナ

信装置を提供することを目的とするものである。[Object of the Invention] The present invention has been made in view of the above circumstances, and provides a vehicle receiving device capable of efficiently guiding an induced voltage of an antenna to a receiver, thereby significantly improving receiving characteristics. It is intended to be provided.
［発明の概要］ この発明は、アンテナの給電端に受信部のアンテナ端子

［発明の実施例］ 以下、この発明の一実施例を図面を参照して詳細に説明
する。[Embodiment of the Invention] An embodiment of the present invention will now be described in detail with reference to the drawings.
第１図は本発明の一実施例を示すブロック図で、車体11
の適当な位置に、空中線12、たとえばロッドアンテナを
突設し、この空中線、すなわちアンテナ12の給電端に受
信部13のアンテナ端子を、直接接続している。なおこの
受信部13は受信した電波から目的の信号を選択し、増
幅、検波して低周波の出力信号を得るものである。FIG. 1 is a block diagram showing an embodiment of the present invention.
An antenna 12, for example, a rod antenna is projected at an appropriate position in the antenna, and the antenna terminal of the receiver 13 is directly connected to the antenna, that is, the feeding end of the antenna 12. The receiving unit 13 selects a target signal from the received radio waves, amplifies and detects it to obtain a low-frequency output signal.
そして、運転席に操作部14を配設し、上記受信部13に制
御ケーブル15を介して制御信号を与えて操作可能とし、
運転者が運転席から選局、音量等の操作を可能としてい
る。Then, the operation unit 14 is arranged in the driver's seat, and a control signal is given to the receiving unit 13 via the control cable 15 to enable operation.
The driver can select the channel and operate the volume from the driver's seat.
そして、バッテリ、ダイナモ等の電源16から電源ケーブ
ル17を介して受信部13に電力を供給し、また受信部13で
復調した低周波出力をスピーカケーブル18を介して、た
とえば車室の後部に配設したスピーカ19へ与えてこれを
駆動し音声出力を得るようにしている。Then, power is supplied from a power source 16 such as a battery or dynamo to the receiving unit 13 via the power cable 17, and the low frequency output demodulated by the receiving unit 13 is distributed via the speaker cable 18 to, for example, the rear part of the vehicle compartment. The speaker 19 provided is driven and driven to obtain a voice output.
このようなアンテナは、第２図の等価回路で示される。Such an antenna is shown in the equivalent circuit of FIG.
第２図において、 ｅはアンテナ誘起電圧、 Caはアンテナ容量（アンテナ固有の有効容量） Cbは給電線容量（給電線によって生じる無効容量） である。In Fig. 2, e is the antenna induced voltage, Ca is the antenna capacity (effective capacity unique to the antenna), and Cb is the feed line capacity (ineffective capacity generated by the feed line).
ここで、給電線容量Cbの両端の信号電圧が、いわゆる有
効として得られる出力電圧となるが、この出力電圧をe0
とすると、アンテナ誘起電圧ｅとの間に次式の関係が生
じる。Here, the signal voltage across the power supply line capacitance Cb is, it becomes the output voltage obtained as a so-called effective, the output voltage e 0
Then, the following relationship is generated between the antenna induced voltage e.
前記した通り、出力電圧e0は、給電線容量Cbの値により
変化し、これが大きいほど出力電圧e0は小さくなること
が分る。 As described above, the output voltage e 0 is changed by the value of the power supply line capacitance Cb, which is greater than the output voltage e 0 is seen that smaller.
しかして、上記実施例によれば上記給電線容量を全く無
くすことができるので、アンテナの誘起電圧を、損失な
く高効率で受信部へ導くことができる。Therefore, according to the above-described embodiment, since the power supply line capacitance can be eliminated at all, the induced voltage of the antenna can be guided to the receiving unit with high efficiency without loss.
たとえば、アンテナ容量Caが15pfのときに、給電線容量
Cbが65pfの場合に、この給電線容量を零にすれば、受信
部の入力電圧レベルは約14db高くなる。For example, when the antenna capacity Ca is 15pf, the feeder line capacity
If Cb is 65 pf and the feed line capacitance is set to zero, the input voltage level of the receiver is increased by about 14 db.
すなわち、アンテナ12の出力を、給電線容量Cb＝65pfの
給電線（約1mの同軸ケーブル）を用いて、受信部に導い
た場合に比較して約14dbの感度の改善が得られる。That is, a sensitivity improvement of about 14 db can be obtained as compared with the case where the output of the antenna 12 is led to the receiving section by using a feed line (coaxial cable of about 1 m) having a feed line capacity Cb = 65 pf.
したがって、アンテナの出力端と受信部を直結（直接接
続）することによりアンテナ誘起電圧を高効率で受信部
へ入力することができ、このため従来よりも小形で低利
得のアンテナを用いても、かえって良好な受信感度を得
ることができる。Therefore, by directly connecting (directly connecting) the output end of the antenna and the receiving unit, the antenna induced voltage can be input to the receiving unit with high efficiency. Therefore, even if a smaller and lower gain antenna than the conventional one is used, On the contrary, good reception sensitivity can be obtained.
さらに、受信部は、たとえばエンジンルーム内に配設
し、運転席には操作部だけを配置すればよいので車室容
積の有効利用を図ることができる。Further, since the receiving unit may be arranged in the engine room, for example, and only the operating unit may be arranged in the driver's seat, it is possible to effectively utilize the vehicle compartment volume.
なお、この発明は、上記実施例に限定されるものではな
く、たとえばアンテナは、ピラーアンテナ、トランクア
ンテナ、窓ガラスアンテナ等を用いてもよいし、アンテ
ナの給電端と受信部とを極めて短く低容量の給電線を用
いて接続してもよいことは勿論である。The present invention is not limited to the above-described embodiment, and for example, a pillar antenna, a trunk antenna, a window glass antenna or the like may be used as the antenna, and the feeding end and the receiving portion of the antenna are extremely short and low. Needless to say, the connection may be made by using a capacity power supply line.
