Description

本発明は、衛星通信用及び移動体通信用等に適したアンテナ装置に関する。   The present invention relates to an antenna device suitable for satellite communication and mobile communication.

衛星通信用及び移動体通信用のアンテナには、省スペース及び低コスト性が求められるため、これらに用いられるアンテナとしては、構成が簡単、形状が小さく、かつ低プロファイルな平面アンテナ（マイクロストリップアンテナ、ＭＳＡ：MicroStrip Antenna）が好ましい。
しかしながら、一般にＭＳＡは狭帯域である課題がある。 Space saving and low cost are required for antennas for satellite communications and mobile communications. Therefore, the antenna used for these antennas is a flat antenna with a simple configuration, a small shape, and a low profile (microstrip antenna). MSA: MicroStrip Antenna) is preferable.
However, in general, MSA has a problem of a narrow band.

ＭＳＡの広帯域化技術の一つとして、給電ピンの内導体がＬ字状のものを用いたアンテナ装置が開示されている（非特許文献１参照）。
図８に、従来技術によるアンテナ装置の概略図を示す。
図８には、断面図Ａ−Ａ´も合わせて示してある。
図８に示すように、アンテナ装置６０は、接地導体ＧＮＤの上方に導体部６１を備える。
給電ピン６２は、内導体６２ａ及び外導体６２ｂで構成され、導体部６１に高周波信号を供給する。
内導体６２ａは、接地導体ＧＮＤを非接触に貫通して、途中でＬ字状に折り曲がり、導体部６１と近接結合する。
また、外導体６２ｂは、接地導体ＧＮＤと接続される。 As one of MSA wideband technologies, an antenna device using an L-shaped inner conductor of a feed pin is disclosed (see Non-Patent Document 1).
FIG. 8 shows a schematic diagram of an antenna device according to the prior art.
FIG. 8 also shows a sectional view AA ′.
As shown in FIG. 8, the antenna device 60 includes a conductor portion 61 above the ground conductor GND.
The power supply pin 62 includes an inner conductor 62 a and an outer conductor 62 b, and supplies a high frequency signal to the conductor portion 61.
The inner conductor 62a penetrates the ground conductor GND in a non-contact manner, is bent in an L shape in the middle, and is closely coupled to the conductor portion 61.
The outer conductor 62b is connected to the ground conductor GND.

従来のアンテナ装置は以上のように構成されているので、アンテナの設置スペースに制限がある場合やアンテナをアレー化することためには、小形化が必要である。
しかし、上記アンテナ装置６０では、給電ピン６２が導体部６１よりも外側に配置されるため、アンテナ全体の占有面積が大きくなる課題がある。 Since the conventional antenna device is configured as described above, it is necessary to reduce the size in order to limit the installation space of the antenna or to arrange the antenna.
However, in the antenna device 60, since the feed pin 62 is disposed outside the conductor portion 61, there is a problem that the occupied area of the entire antenna increases.

本発明は、上記課題を解決するためになされたものであり、小形なアンテナ装置を提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object thereof is to provide a small antenna device.

本発明のアンテナ装置は、内部に第１の導体貫通部を有し、接地導体と非接触に設けられた第１の導体部を備え、第１の給電ピンの内導体は、接地導体及び第１の導体部の第１の導体貫通部を非接触に貫通して延伸し、概ね９０度に折れ曲がり、第１の導体部と近接して概ね平行に配置されたものである。   The antenna device of the present invention includes a first conductor penetrating portion therein and a first conductor portion provided in a non-contact manner with the ground conductor. The inner conductor of the first feed pin includes the ground conductor and the first conductor. The first conductor portion extends through the first conductor through portion in a non-contact manner, is bent at approximately 90 degrees, and is disposed in parallel and in close proximity to the first conductor portion.

本発明によれば、第１の給電ピンの内導体が、第１の導体部の内側に配置されるため、アンテナ全体の占有面積を小さくし、従来の特性を保持しつつ、小形なアンテナ装置を提供することができる効果がある。   According to the present invention, since the inner conductor of the first feeding pin is arranged inside the first conductor portion, a small antenna device is achieved while reducing the occupied area of the entire antenna and maintaining the conventional characteristics. There is an effect that can be provided.
