従来、この種のアンテナとしては、図３に示すものがあった。この図は例えば 、栗林他、「２周波共用マイクロストリップアンテナ」、昭和５７年電子通信学 会総合全国大会、６４３に示されるもので、図において１は低域用円環パッチア ンテナ、２は高域用円形パッチアンテナ、３は接地導体、４は低域用給電ピン、 ５は高域用給電ピン、６は地導体、７は誘電体基板を示す。 Conventionally, this type of antenna has been shown in FIG. This figure is shown in, for example, Kuribayashi et al., "Microwave Strip Antenna for Dual Frequency," 643, National Conference of the Institute of Electronics and Communication Engineers, 643, in which 1 is a low-frequency ring patch antenna, and 2 is a high frequency patch antenna. Area circular patch antenna, 3 is a ground conductor, 4 is a low-frequency power supply pin, 5 is a high-frequency power supply pin, 6 is a ground conductor, and 7 is a dielectric substrate.
【０００３】 次に動作について説明する。低域用円環パッチ１は誘電体基板１上に構成され 、その内側の円周が接地導体３により地導体７に接地されている。さらに、低域 用給電ピン４により、アンテナ背面より給電される。ここで、低域の円環パッチ アンテナは、数１に示す周波数においてＴＭ１１モードで励振され、効率よく電 波を放射する。Next, the operation will be described. The low frequency circular patch 1 is formed on the dielectric substrate 1, and the inner circumference thereof is grounded to the ground conductor 7 by the ground conductor 3. Further, the low frequency power supply pin 4 supplies power from the back of the antenna. Here, the low-frequency circular patch antenna is excited in the TM11 mode at the frequency shown in Formula 1, and efficiently radiates the electromagnetic wave.

【数１】 [Equation 1]
【０００５】 一方、高域用円形パッチアンテナ２は、誘電体基板６上に構成され、背面より 高域用給電ピン５により給電される。ここで、高域用円形パッチアンテナ２は数 ２に示す周波数においてＴＭ１１モードで励振され、効率よく電波を放射する。On the other hand, the high-frequency circular patch antenna 2 is formed on the dielectric substrate 6, and is fed from the back surface by the high-frequency feeding pin 5. Here, the high-frequency circular patch antenna 2 is excited in the TM11 mode at the frequency shown in Formula 2 and efficiently radiates radio waves.
【０００６】[0006]
【数２】 [Equation 2]
【０００７】 従って、高域のアンテナの共振半径は、低域のアンテナの共振半径よりも小さ くなる。ここで、図３に示すように、高域用給電ピン５は低域用円環パッチアン テナ１の円環内部を通っているから、低域用給電ピン４および低域用円環アンテ ナ１の特性には影響を与えない。従って、２つの周波数帯のアンテナの特性はそ れぞれ独立となり、両者を独立に設計することが可能であるという特徴を有して いる。Therefore, the resonance radius of the high band antenna becomes smaller than the resonance radius of the low band antenna. Here, as shown in FIG. 3, since the high frequency power supply pin 5 passes through the inside of the ring of the low frequency ring patch antenna 1, the low frequency power supply pin 4 and the low frequency ring antenna 1 are provided. Does not affect the characteristics of. Therefore, the characteristics of the antennas in the two frequency bands are independent of each other, and both have the characteristic that they can be designed independently.

従来の周波数共用アンテナは以上のように構成されていたので、例えばＧＰＳ 用としてＬ帯の円環パッチ、ＲＡＣＳ用としてＳ帯の円形パッチを重ねて二周波 共用アンテナを構成することができるが、この場合誘電体基板２枚を積層する必 要があり、アンテナのコストが高くなるという問題点があった。 Since the conventional frequency sharing antenna is configured as described above, a dual frequency sharing antenna can be configured by stacking an L band circular patch for GPS and an S band circular patch for RACS, for example. In this case, it is necessary to stack two dielectric substrates, which increases the cost of the antenna.
【０００９】 この考案は、上記の課題を解消するためになされたもので、誘電体基板層を減 らし、１層で２周波共用アンテナ、あるいは２層で３周波共用アンテナを構成す ることにより、安価な周波数共用アンテナを得るものである。This invention has been made in order to solve the above-mentioned problems, and by reducing the dielectric substrate layer and forming a dual-frequency antenna with one layer or a dual-frequency antenna with two layers, , To obtain an inexpensive frequency sharing antenna.

この考案に係わる周波数共用アンテナは、低域の周波数帯に対するアンテナを 円環パッチアンテナ、高域の周波数帯に対するアンテナを円形パッチアンテナと するとともに、高域のアンテナを低域と同一面の円環の内側に配置して構成した ものである。 In the frequency sharing antenna according to the present invention, the antenna for the low frequency band is a circular patch antenna, the antenna for the high frequency band is a circular patch antenna, and the high frequency antenna is the same plane as the low frequency band. It is configured by being placed inside the.
【００１１】 また、低域および中域の周波数帯に対するアンテナを円環パッチアンテナ、高 域の周波数帯に対するアンテナを円形パッチアンテナとし、高域のアンテナを中 域と同一面の円環の内側に配置して構成し、これを低域のアンテナ上部に積層し て構成したものである。Further, an antenna for the low and mid frequency bands is a circular patch antenna, an antenna for the high frequency band is a circular patch antenna, and the high frequency antenna is inside a circular ring on the same plane as the mid frequency band. It is configured by arranging and arranging it, and stacking this on the upper part of the low frequency antenna.
【００１２】[0012]
上記のように構成された周波数共用アンテナは、低域のアンテナと高域のアン テナを同一面上に構成できるため、誘電体基板一層で２周波共用アンテナを構成 することができる。 In the frequency sharing antenna configured as described above, the low frequency antenna and the high frequency antenna can be configured on the same plane, and thus the dual frequency antenna can be configured with a single dielectric substrate.
【００１３】 また、中域のアンテナと高域のアンテナを同一面に構成できるから、誘電体基 板２層で３周波共用アンテナを構成できる。Further, since the antenna in the middle band and the antenna in the high band can be formed on the same surface, the antenna for three frequencies can be formed by two layers of the dielectric substrate.

実施例１． 図１は、この考案の実施例１を示す構成図である。図において、１は低域用円 環パッチアンテナ、２は高域用円形パッチアンテナ、３は接地導体、４は低域用 給電ピン、５は高域用給電ピン、６は地導体、７は誘電体基板を示す。 Example 1. FIG. 1 is a configuration diagram showing a first embodiment of the present invention. In the figure, 1 is a low-frequency circular patch antenna, 2 is a high-frequency circular patch antenna, 3 is a ground conductor, 4 is a low-frequency power supply pin, 5 is a high-frequency power supply pin, 6 is a ground conductor, and 7 is a ground conductor. 3 shows a dielectric substrate.
【００１５】 図において、低域用円環パッチ１の内円の半径ｂ1 を高域用円形パッチ２の半 径ａh よりも大きくなるように選定し、かつ高域用円形パッチ２を低域用円環パ ッチ１と同一基板上の円環の内側に形成する。この構成において、高域用給電ピ ン５は、接地導体３によって低域用給電ピン４と分離されているから、アンテナ 相互の影響は少なく、従って２つの周波数帯のアンテナを独立に設計できるとい う特徴を維持したまま、誘電体基板一層で二周波共用アンテナを構成することが できる。この構成により、例えば低域用としてＧＰＳ用Ｌ帯円環パッチ、高域用 としてＡＭＴＩＣＳ用Ｋｕ帯円形パッチを用いた２周波共用アンテナを構成する ことができる。In [0015] Figure, selects the radius b 1 of the inner circle of the circle for the low frequency ring patch 1 to be larger than the radius a h of the high-frequency circular patch 2, and a circular patch 2 for high-frequency low It is formed inside the circular ring on the same substrate as the circular ring patch 1. In this configuration, the high-frequency power supply pin 5 is separated from the low-frequency power supply pin 4 by the grounding conductor 3, so that the mutual effects of the antennas are small, and therefore the antennas for the two frequency bands can be designed independently. It is possible to configure a dual frequency antenna with a single dielectric substrate while maintaining such characteristics. With this configuration, it is possible to configure a dual frequency antenna using, for example, an L band annular patch for GPS for the low band and a Ku band circular patch for the AMTICS for the high band.
【００１６】 実施例２． 図２は、この考案の実施例２を示す概略構成図である。図において、１〜７は 、実施例１と同等であり、８は中域用円環パッチアンテナ、９は中域用給電ピン を示す。Example 2. Second Embodiment FIG. 2 is a schematic configuration diagram showing a second embodiment of the present invention. In the figure, 1 to 7 are equivalent to those of the first embodiment, 8 is an annular patch antenna for the mid range, and 9 is a feeding pin for the mid range.
【００１７】 図において、高域用円形パッチアンテナ２は、中域用円環パッチアンテナ８と 同一面に構成され、さらに低域用円環パッチアンテナ１の上部に積層されて構成 される。この構成において、低域用給電ピン４、高域用給電ピン５、中域用給電 ピン９は互いに接地導体３により分離されているから、互いに結合することがな く、従って各周波数帯のアンテナを独立に設計できるという特徴を維持したまま 、誘電体基板２層で３周波共用アンテナを構成できる。この構成により、例えば 低域用としてＧＰＳ用Ｌ帯円環パッチアンテナ、中域用としてＲＡＣＳ用Ｓ帯円 環パッチアンテナ、高域用としてＡＭＴＩＣＳ用Ｋｓｕ帯円形パッチアンテナを 用いた３周波共用アンテナを得ることが可能である。In the figure, a high band circular patch antenna 2 is formed on the same plane as the middle band circular patch antenna 8 and further laminated on the lower band circular patch antenna 1. In this configuration, the low-frequency power supply pin 4, the high-frequency power supply pin 5, and the mid-frequency power supply pin 9 are separated from each other by the ground conductor 3, and therefore are not coupled to each other, and therefore the antennas of each frequency band are provided. It is possible to construct a three-frequency shared antenna with two layers of the dielectric substrate while maintaining the feature that each can be independently designed. With this configuration, for example, a three-frequency shared antenna using an L band circular ring patch antenna for GPS for low frequency band, an S band circular ring patch antenna for RACS for middle frequency band, and a Ksu band circular patch antenna for AMTICS for high frequency band is used. It is possible to obtain.
