図１１、図１２を用いて係合部７０の具体的な実施形態の一例を説明する。図１１が全体図、図１２が部分拡大図である。 An example of a specific embodiment of the engaging portion 70 will be described with reference to FIGS. 11 and 12. FIG. 11 is an overall view, and FIG. 12 is a partially enlarged view.

係合部７０は、トップカバー２０の裏面側に形成されている第１の係止部７１と、第１および第２の可動グランド４２、４３のそれぞれの先端側に形成されている第２の係止部７２とを有する。実施形態では係合部７０の一例として爪係合を用いている。係合部７０が係止状態にあるときは、第１のカバー部材１３とトップカバー２０との間に設けられている弾性部材６５が押圧された圧縮状態にある。 The engaging portion 70 is a first locking portion 71 formed on the back surface side of the top cover 20 and a second end formed on the tip side of each of the first and second movable grounds 42 and 43. And a locking portion 72. In the embodiment, claw engagement is used as an example of the engagement portion 70. When the engaging portion 70 is in the locked state, the elastic member 65 provided between the first cover member 13 and the top cover 20 is in a compressed state in which it is pressed.

本実施形態では、弾性部材６５の一例としてバネを用いている。弾性部材６５は複数設けられ、第１のカバー部材１３の第２の面１３ｂに形成された凹部１３ｃにその一端が載置され、他端はトップカバー２０の内面側に固定されている。 In the present embodiment, a spring is used as an example of the elastic member 65. A plurality of elastic members 65 are provided, one end of which is placed in the recess 13 c formed in the second surface 13 b of the first cover member 13, and the other end is fixed to the inner surface side of the top cover 20.

係合部７０を解除する場合は、本実施形態では、ケース１０の両側面１０ａ、１０ｂから指で係合部７０を押圧する。押圧すると、第１および第２の可動グランド４２、４３がケース１０内部に押し込まれ、第１の係止部７１と第２の係止部７２の係合が外れる（図１２（ｂ）参照）。そして、弾性部材６５が伸長状態になり、トップカバー２０がケース１０の上方に離間し、第１および第２の可動グランド４２、４３をケース１０の外部に引き出すことが可能となる（図１１（ｂ）、図１２（ｃ）参照）。 When releasing the engaging part 70, in this embodiment, the engaging part 70 is pressed with the finger from the both side surfaces 10a, 10b of the case 10. When pressed, the first and second movable grounds 42 and 43 are pushed into the case 10, and the engagement between the first locking portion 71 and the second locking portion 72 is released (see FIG. 12B). . And the elastic member 65 will be in the expansion | extension state, the top cover 20 will space apart above the case 10, and it will become possible to pull out the 1st and 2nd movable grounds 42 and 43 to the exterior of FIG. b), see FIG.

本実施形態では、係合部７０を構成する第１の係止部７１と第２の係止部７２の一例として爪形状を説明したが、ランスと突起、凹凸係合や嵌合等を採用しても良く、機械的係止や電気的係止が選択可能であり、本実施形態で示される係合部７０の構造に限定されない。また、第１および第２の可動グランド４２、４３に第２の係止部７２を設けた例を述べたが、第２の係止部７２をケース１０に形成しても良い。 In the present embodiment, the claw shape has been described as an example of the first locking portion 71 and the second locking portion 72 that constitute the engaging portion 70, but a lance and a protrusion, concave and convex engagement, fitting, and the like are adopted. Alternatively, mechanical locking or electrical locking can be selected, and the structure is not limited to the structure of the engaging portion 70 shown in the present embodiment. Moreover, although the example which provided the 2nd latching | locking part 72 in the 1st and 2nd movable grounds 42 and 43 was described, you may form the 2nd latching | locking part 72 in the case 10. FIG.

第１の係止部７１と第２の係止部７２が係止状態で固定されている時は、弾性部材６５が圧縮状態で、トップカバー２０のケース１０に対する相対距離が小さくなった接近状態が実現され、アンテナ装置１の小型化を実現できる。また、第１の係止部７１が第２の係止部７２から解除され弾性部材６５が伸長状態となりトップカバー２０がケース１０から離間することにより、トップカバー２０のケース１０に対する相対距離が大きくなった離間状態が実現される。そして、トップカバー２０のケース１０に対する相対位置が変動し、グランド４０および第１のアンテナ素子５０に対する第２のアンテナ素子５５の距離が変動する。 When the first locking portion 71 and the second locking portion 72 are fixed in a locked state, the elastic member 65 is in a compressed state and the approaching state in which the relative distance of the top cover 20 to the case 10 is reduced. Thus, the antenna device 1 can be downsized. Further, when the first locking portion 71 is released from the second locking portion 72 and the elastic member 65 is extended and the top cover 20 is separated from the case 10, the relative distance of the top cover 20 to the case 10 is increased. The separated state is realized. Then, the relative position of the top cover 20 with respect to the case 10 varies, and the distance between the ground 40 and the second antenna element 55 with respect to the first antenna element 50 varies.

トップカバー２０が弾性部材６５の作用でケース１０の上方に移動し、グランド４０および第１のアンテナ素子５０に対する無接点アンテナ素子である第２のアンテナ素子５５との距離が相対的に大きくなり、衛星無線通信の周波数帯域が拡がる。次に、２つの可動グランド４２、４３を両側面１０ａ、１０ｂから引き出すことによりグランド４０の面積が大きくなり、衛星通信用のアンテナとしての指向性が高まり、衛星通信が可能となる。これにより、本実施形態のアンテナ装置１は小型で携帯型の装置であり、簡単な操作で無線通信用として使用可能であり、持ち運びが容易であり、アンテナ装置１の利便性が増す。そして、地上通信用アンテナ素子３０を、ケース１０を支持する支持脚として利用し、アンテナ装置１、より具体的には第１のアンテナ素子５０、第２のアンテナ素子５５およびグランド４０の衛星に対する角度を自由に設定可能となるため、これらの部材が衛星に対して利得の高い位置に設定できる。 The top cover 20 moves above the case 10 by the action of the elastic member 65, and the distance between the ground 40 and the second antenna element 55 that is a contactless antenna element with respect to the first antenna element 50 becomes relatively large. The frequency band of satellite wireless communication is expanded. Next, by pulling out the two movable grounds 42 and 43 from both side surfaces 10a and 10b, the area of the ground 40 is increased, the directivity as an antenna for satellite communication is increased, and satellite communication is possible. Thereby, the antenna device 1 of this embodiment is a small and portable device, can be used for wireless communication with a simple operation, is easy to carry, and the convenience of the antenna device 1 is increased. Then, the ground communication antenna element 30 is used as a support leg for supporting the case 10, and the angle of the antenna device 1, more specifically, the first antenna element 50, the second antenna element 55, and the ground 40 with respect to the satellite. Can be set freely, so that these members can be set at a position having a high gain with respect to the satellite.

なお、地上通信用アンテナ素子３０は、図２に示す様に起立させた状態で機能するだけでなく、図１に示す様にケース１０に収納された状態で機能するようにしても良い。 The ground communication antenna element 30 may function not only in a standing state as shown in FIG. 2, but also in a state of being housed in the case 10 as shown in FIG.

このように、本実施形態に係るアンテナ装置１によれば、第１のアンテナ素子５０を第１の位置までスライドさせることで、直線偏波給電点６１ａ，６１ｂにのみ電気的に接続し、第１のアンテナ素子５０を第２の位置までスライドさせることで、円偏波給電点６１ｃ，６１ｄにのみ電気的に接続するので、スイッチを使用することなく地上通信と衛星通信の切り替えを行うことができる。即ち、アンテナ性能を損なうことなく地上通信と衛星通信の切り替えを行うことができる。また、第１のアンテナ素子５０をスライドするだけで衛星通信が可能となるので、災害等の緊急時においても容易に取り扱うことができる。また、地上通信と衛星通信の切り替えを行うスイッチを必要としないことと、１つの第１のアンテナ素子５０を地上通信と衛星通信とで共用できることで小型化が図れるとともにコストの削減も図れる。 As described above, according to the antenna device 1 according to the present embodiment, the first antenna element 50 is electrically connected only to the linearly polarized wave feeding points 61a and 61b by sliding the first antenna element 50 to the first position. By sliding one antenna element 50 to the second position, it is electrically connected only to the circularly polarized wave feeding points 61c and 61d. Therefore, switching between ground communication and satellite communication can be performed without using a switch. it can. That is, switching between ground communication and satellite communication can be performed without impairing antenna performance. Further, since the satellite communication can be performed only by sliding the first antenna element 50, it can be easily handled in an emergency such as a disaster. Further, since a switch for switching between terrestrial communication and satellite communication is not required and one first antenna element 50 can be shared by terrestrial communication and satellite communication, the size can be reduced and the cost can be reduced.
