するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an antenna device, and its purpose is to integrate an omnidirectional transmitting antenna and a receiving antenna with single directivity in four directions into an integrated structure, so that it can be used on the top plate of a color television receiver, etc. The present invention aims to provide an antenna that can be easily installed in a vehicle and used to easily display the direction and distance of a moving object.
以下実施例として示した図面に従いその構成を説明する
。The configuration will be described below with reference to the drawings shown as examples.
１は無指向性の送信アンテナで、金属製の円板状の台」
二に垂直状に樹立されている。1 is an omnidirectional transmitting antenna, which is a metal disc-shaped base.
It is erected vertically on two sides.
２は送信アンテナ下方の支柱で、送信アンテナ１とは絶
縁体３を介して設けであるシールドケースとしての役目
も果しており、およそ２０ｃＩｒＬ位の高さを有する。Reference numeral 2 denotes a post below the transmitting antenna, which also serves as a shield case that is connected to the transmitting antenna 1 via an insulator 3, and has a height of about 20 cIrL.
４は支柱を中心に９０°毎に配設された受信バーアンテ
ナで、フェライト等の磁性体５の中央周面にボビン６を
介してコイル７が巻付けである。Reference numeral 4 denotes a receiving bar antenna arranged every 90° around the pillar, and a coil 7 is wound around the central circumferential surface of a magnetic material 5 such as ferrite via a bobbin 6.
コイル７はそれぞれのバーアンテナ４毎に細い同軸ケー
ブル８によって、カラーテレビジョン受像機に附加した
４アンテナ受信部に導ひかれている。The coil 7 is guided by a thin coaxial cable 8 for each bar antenna 4 to a four-antenna receiver attached to the color television receiver.
９はバーアンテナ４の両端を遮断するように支柱２から
９０°角毎に立設したアルミニューム又は黄銅製の磁気
シールド板で、およそ１４０Ｘ ２００−一の大きさを
有する。Reference numeral 9 denotes a magnetic shield plate made of aluminum or brass that is erected every 90 degrees from the pillar 2 so as to block both ends of the bar antenna 4, and has a size of about 140 x 200 -1.
１０はバーアンテナ４を磁気シールド板９へ取付けるた
めの樹脂その他絶縁性の取付アングルである。10 is a mounting angle made of resin or other insulating material for mounting the bar antenna 4 to the magnetic shield plate 9.
本発明は上記のような構成をとったので、無指向性送信
アンテナ１は４方向指向性の受信アンテナとしてのバー
アンテナ４と一体構造を採ることができ、コンパクトに
構成されているので、テレビジョン受像機の天板等室内
に設置可能である。Since the present invention has the above-described configuration, the omnidirectional transmitting antenna 1 can be integrated with the bar antenna 4 as a four-directional directional receiving antenna, and is compactly configured. It can be installed indoors, such as on the top of a John receiver.
又それぞれのバーアンテナ４ではその両端で９０゜角毎
に立設された磁気シールド板９が存在するので、１８０
°逆方向からの電磁波等に対して感度をもたないように
構成されている。Also, since each bar antenna 4 has magnetic shield plates 9 erected at 90° angles at both ends,
° It is constructed so that it is not sensitive to electromagnetic waves etc. from the opposite direction.
従って、各バーアンテナは磁気シールド板９で囲われた
範囲からの電磁波等をキャッチし、この誘起電圧はそれ
ぞれ単独に同軸ケーブル８を介して、テレビジョン受像
機へ伝送されるようになっており、各信号間のクロスト
ークは生じない等の効果がある。Therefore, each bar antenna catches electromagnetic waves etc. from the area surrounded by the magnetic shield plate 9, and this induced voltage is individually transmitted to the television receiver via the coaxial cable 8. , crosstalk between signals does not occur.
