In the figure, reference numeral 1 denotes a transmission / reception module, to which an output side RF socket connector 1a, an input side RF socket connector 1b and a power signal input multi-pole pin connector 1c are attached. An open element substrate 2 has an open patch 2a made of copper foil on the front surface, a ground conductor 2b on the back surface, and an RF pin connector 2c soldered thereto. Reference numeral 3 denotes an opening bracket made of a conductive material such as aluminum, which is bonded and integrated with the opening element substrate with a conductive adhesive to form an opening element antenna. The aperture element antenna and the transmission / reception module are electrically coupled by an RF connector and mechanically by a screw 4 to form an antenna module. Like the opening bracket, 5 is a grid-shaped front plate made of a conductive material such as aluminum, which divides the insertion position of the antenna module into a honeycomb shape. 6 is a power supply control board, 6a is a multi-pole socket connector, 7 is a microwave feeding circuit, and 7a is an RF pin connector. Further, 8 is a screw for fixing the antenna module. FIG. 4 is a partial front view of a conventional electronic scanning antenna. A typical electronic scanning antenna is constructed by arranging 1000 or more aperture element substrates 2 in a plane. In the figure, 5a is a screw hole provided in the lattice portion of the front plate, and arrow A shows the electric field direction of the radio wave radiated from the aperture element antenna.

【0003】 従来の電子走査アンテナは上記のように構成されており、アンテナモジュール はフロントプレート5にて区分けされた規定の位置に挿入され、多極ピンコネク タ1cが電源制御基板6の多極ソケットコネクタ6aと、RFソケットコネクタ 1bがマイクロ波給電回路7のRFピンコネクタ7aと嵌合すると共に、前面よ りネジ8にてフロントプレートに締め付け固定される。ネジ8により開口ブラケ ットとフロントプレートが密着させられることにより、アンテナ内部つまり送受 信モジュール側への電界の漏れ込みが防止されると共に、隣接する開口素子アン テナの地導体がフロントプレートを介して同電位に保たれ、各々の開口素子アン テナが所要の電波を放射する条件が整うこととなる。The conventional electronic scanning antenna is configured as described above, the antenna module is inserted into a prescribed position divided by the front plate 5, and the multipole pin connector 1c is a multipole socket of the power supply control board 6. The connector 6a and the RF socket connector 1b are fitted to the RF pin connector 7a of the microwave feeding circuit 7, and are fastened and fixed to the front plate by the screws 8 from the front surface. The screw 8 allows the opening bracket and the front plate to come into close contact with each other, thereby preventing the electric field from leaking into the inside of the antenna, that is, the transmitting and receiving module side, and the ground conductor of the adjacent opening element antenna via the front plate. Are kept at the same potential, and the conditions under which each aperture element antenna radiates the required radio waves are set.

【考案が解決しようとする課題】[Problems to be solved by the device]

上記のような従来の電子走査アンテナでは、アンテナモジュールは前面からネ ジ止めされる構造のため、開口素子アンテナから放射される電波の一部がこのネ ジ頭により反射され、合成されたアンテナパターン特性が劣化するという課題が あった。また、特に10GHz等の高周波帯用アンテナの場合は、開口素子アン テナピッチが小さく1000ケ以上にものぼる上記のネジ8はM2ネジ程度のサ イズしか使えないため、フロントプレートの格子部へのネジ穴加工は困難で長時 間を要していた。さらにまた、アンテナモジュール整備に際してのネジ脱着時に は、ネジの脱落紛失及びフロントプレートのネジ山損傷等の問題が付きまとい整 備性に欠けるという課題があった。 In the conventional electronic scanning antenna as described above, the antenna module is fixed from the front side, so part of the radio wave radiated from the aperture element antenna is reflected by this head and the antenna pattern is synthesized. The problem was that the characteristics deteriorated. Also, especially in the case of antennas for high frequency bands such as 10 GHz, the above-mentioned screws 8 with a small aperture element antenna pitch of 1,000 or more can use only M2 screw sizes, and therefore screws to the grid part of the front plate. Drilling was difficult and took a long time. Furthermore, when attaching and detaching the screws when servicing the antenna module, there were problems such as loss and loss of the screws and damage to the threads of the front plate, and there was the problem of lack of maintainability.

【0005】 この考案は、かかる課題を解決するためになされたもので、アンテナパターン 特性の劣化がなく、困難で長時間を要するネジ穴加工を必要とせず、かつ整備性 に優れたアンテナモジュールの固定方法を有する電子走査アンテナを得ることを 目的とする。The present invention has been made to solve the above problems, and an antenna module which has no deterioration in antenna pattern characteristics, does not require difficult and long-time screw hole machining, and has excellent maintainability. The aim is to obtain an electronic scanning antenna with a fixing method.

【課題を解決するための手段】[Means for Solving the Problems]

この考案に係わる電子走査アンテナは、アンテナモジュールの開口ブラケット 部に板バネと所要の可撓性を有するラバーを配設し、この板バネとフロントプレ ートの格子部を圧接させることにより、アンテナモジュールを固定保持する構成 とした。 In the electronic scanning antenna according to the present invention, a leaf spring and a rubber having a required flexibility are arranged in the opening bracket portion of the antenna module, and the leaf spring and the lattice portion of the front plate are pressed to contact each other, so that the antenna is The module is fixedly held.

【0007】[0007]

【作用】 この考案においては、アンテナモジュールは板バネとフロントプレート格子部 との圧接にて固定保持される構造のため、隣接する開口素子アンテナはフロント プレートを介して電気的に接続され地導体は同電位に保たれる。また1000ケ 以上にものぼるフロントプレートの格子部へのネジ穴加工及び固定用ネジが不要 となる。In this invention, since the antenna module is structured such that the leaf spring and the front plate lattice are pressed and held, adjacent aperture element antennas are electrically connected through the front plate and the ground conductor is It is kept at the same potential. In addition, it is not necessary to machine screw holes and fixing screws in the lattice of the front plate, which amount to more than 1000 pieces.

FIG. 1 is a partial cross-sectional view showing an embodiment of the present invention, and 1 to 7 show the same as or equivalent to the above-mentioned conventional example. Reference numeral 9 is a leaf spring which is arranged at the interface between the aperture element antenna and the transmission / reception module and is bent to cover both sides of the aperture bracket 3 in the electric field direction of the aperture element. 10 is a gap between the leaf spring and the side surface of the aperture bracket. It is a rubber that has the required flexibility and is embedded in. FIG. 2 is a three-dimensional view showing in detail the vicinity of the aperture element antenna of the antenna module according to the present invention.

【0009】 上記のように構成された電子走査アンテナにおいては、フロントプレート6に て区分けされた規定の位置に挿入されたアンテナモジュールは板バネとフロント プレート格子部との圧接にて固定保持される。この際上記可撓性を有するラバー 10は接触圧を補充強化すると共に、板バネの型くずれを防ぎ両サイドの接触圧 を均等に保つ役割をなす。また、板バネとフロントプレートが圧接することによ り電気的にも接続され、アンテナ内部への電界の漏れ込みが防止されると共に、 隣接する開口素子アンテナの地導体2bが同電位に保たれ各々の開口素子アンテ ナが所要の電波を放射する条件が整備される。In the electronic scanning antenna configured as described above, the antenna module inserted into the prescribed position divided into the front plate 6 is fixed and held by pressure contact between the leaf spring and the front plate lattice portion. . At this time, the flexible rubber 10 replenishes and reinforces the contact pressure, and also prevents the leaf spring from losing its shape and keeps the contact pressure on both sides uniform. Further, the leaf spring and the front plate are pressed into contact with each other to be electrically connected, preventing the electric field from leaking into the antenna, and keeping the ground conductor 2b of the adjacent aperture element antenna at the same potential. The conditions for each aperture element antenna to radiate the required radio waves are established.

【考案の効果】[Effect of the device]

この考案は、以上説明したように構成されているので、以下に示すような効果 を奏する。 Since the present invention is configured as described above, it has the following effects.

【0011】 アンテナモジュールのネジ止めが不要となりアンテナ前面にネジ頭が露出しな いため、ネジ頭での電波の反射によるアンテナパターン特性劣化がなくなる。Since the screwing of the antenna module is not necessary and the screw head is not exposed on the front surface of the antenna, the antenna pattern characteristic deterioration due to the reflection of radio waves at the screw head is eliminated.

【0012】 加工が困難で長時間を要していた1000ケ以上にものぼるフロントプレート の格子部への小ネジ穴加工が不要となる上、アンテナモジュール整備性が格段に 向上する。It is not necessary to process small screw holes in the grid portion of the front plate, which is difficult to process and requires a long time, and the number of screws is 1000 or more, and the maintainability of the antenna module is significantly improved.
