That is, the first element hinge unit 513 is inserted into the open bottom surface of the transfer body 511 so that the end of the inserted first connection bar 610 is communicatively inserted into both side walls and rotatably fixed.

That is, the transmission block 510 is hinged to the first connection bar 610, which is fixed to the outer surface of the first antenna element 200 and extends from the lower side.

The sliding block 520 includes a sliding body 521 having communicating holes 522 and 522 formed at its central portion to be slidably fitted on an outer surface of the second antenna element 300, A first hinge groove 523 which forms a space for hinge-connecting the first connecting bar 610 and a second hinge groove 523 which forms a space for hinging the second connecting bar 620 on the opposite side of the first hinge groove 523, And two hinge grooves 524.

The sliding body 521 is formed with a communication hole 522 at the center thereof and is slid along the outer surface of the second antenna element 300. Alternatively, the sliding body 521 may be fixed to the outer surface of the second antenna element 300.

The second connecting bar 620 is rotated between the second antenna element 300 and the intermediate supporting member 400 while the second strut 120 is lifted and lowered so that the second antenna element 300 is lifted from the elevation angle .

The first connection bar 610 is configured to lift the first antenna element 200 from the lower side according to the rotation of the second antenna element 300 while the support rod is lifted and lowered, And is rotated from the upright state to the horizontal state.

At this time, the sliding block 520 slides along the outer surface of the second antenna element 300 while interlocking with the rotation of the first connection bar 610 and the second connection bar 620, Thereby facilitating the rotation of the two connection bars 620. That is, the sliding block 520 moves up and down along the outer surface of the second antenna element 300 in a state where the first antenna element 200 and the second antenna element 300 are unfolded. In the folding process, And rotates the bar 610 and the second connecting bar 620 in opposite directions.

The present invention includes the above-described configuration, and the operation and effect of the present invention will be described in more detail below.

First, the automatically expandable broadband disc antenna according to the present invention is transportable in the assembled state.

That is, the strut member 100 is configured to be able to contract and extend in a state in which a plurality of strut rods are overlapped (antenna type). For example, if the elevation angle support member 800 is composed of the first strut 110, the second strut 120, and the third strut 130 in the order of larger diameters, The third strut 130 is located at the uppermost position of the third strut 130. [

At this time, the second strut 120 is automatically lifted or lowered along the outer surface of the third strut 130 by the driving member 900.

The first antenna element 200 and the second antenna element 300 are folded to be in close contact with the outer surfaces of the second strut 120 and the third strut 130, respectively.

That is, one end of the first antenna element 200 is hinged to the first insertion groove 822 of the horizontal rotation body 821 of the elevation support member 800 and is rotated toward the third support rod 130, As shown in Fig.

One end of the second antenna element 300 is hinged to the second insertion groove 832 of the elevation rotary body 831 of the elevation support member 800 so as to be close to the side of the third support rod 130, State.

At this time, the elastic body 720 is held in a folded state along the first antenna element 200 in a folded state such that the first antenna element 200 is in close contact with the outer surface of the third support bar 130.

The element supporting member 600 may include a first connecting bar 610 folded between the first antenna element 200 and the second antenna element 300 to form a first antenna element 200 and a second antenna element 300, 300). In addition, the second connection bar 620 maintains a folded state between the second antenna element 300 and the intermediate support member 400.

As described above, the automatically expandable broadband disc antenna according to the present invention is disassembled as compared with the case where the first antenna element 200 and the second antenna element 300 are moved in a collapsed state, There is no time, and when parts are disassembled, the problem of missing parts is prevented in advance.

When the assembled state is conveyed to the installation place, the operator operates the on-switch of the driving member 900 to operate the driving member 900. The driving member 900 extends the strut member 100 folded in an antenna manner as a hydraulic or pneumatic cylinder. That is, the second strut 120 accommodated in the first strut 110 is stretched.

Therefore, the second strut 120 extends along the outer surface of the third strut 130 according to the operation of the driving member 900. Accordingly, the first connecting bar 610 and the second connecting bar 620 are rotated outward as the distance between the elevation supporting member 800 and the intermediate supporting member 400 is narrowed.

In addition, the sliding block 520 is moved up and down along the outer surface of the second antenna element 300 while the first connecting bar 610 and the second connecting bar 620 are rotated outward.

At this time, in the first connecting bar 610, the lower end is rotated to the outside of the second strut 120 while the sliding block 520 is moved, and the upper end is rotated from the intermediate block 420 to the elevation supporting member 800 side And is turned into an upright state.

That is, the first connecting bar 610 and the second connecting bar 620 are moved up and down along the outer surface of the third strut 130 so that the first and second connecting bars 610, The element 300 is pressed and rotated.

Accordingly, the first antenna element 200 is upwardly moved by an upward force from the lower side through the first connection bar 610 hinged at the transfer block 510 fixed to the outer surface, The second connecting bar 620 is rotated outward and the sliding block 520 is rotated by the force of sliding along the outer surface of the second antenna element 300.

At this time, the first antenna element 200 is rotated from the vertical direction to the horizontal direction by the assist force by the force to restore the elastic body 720 to its original position. Accordingly, the first antenna element 200 and the second antenna element 300 can be completely developed within the same time range despite the difference in the radius of gyration.

As described above, the first antenna element 200 and the second antenna element 300 are not installed manually by an operator but can be installed within a short period of time as they are automatically deployed by the driving member 900. That is, it is suitable for military or civilian use where frequent movements are required.

In addition, the withdrawal operation of the broadband disconnection antenna according to the present invention is performed in reverse to the above-described process. That is, the operator inputs a command to actuate the driving member 900 to retract the second strut 120. [ Then, the second strut 120 moves downward along the outer surface of the third strut 130 and moves to the outer surface or the inner side of the first strut 110.

Therefore, the distance between the elevation supporting member 800 and the intermediate supporting member 400 is increased. Therefore, the first connection bar 610 and the second connection bar 620 are rotated in the direction opposite to the direction of rotation when the first antenna element 200 and the second antenna element 300 are folded in the extended state, .

That is, the first connection bar 610 is rotated in a direction opposite to the unfolding direction to pull the first antenna element 200 downward to rotate, and the second connection bar 620 rotates the second antenna element 300 downward .

Therefore, the first antenna element 200 and the second antenna element 300 are folded so as to be in close contact with the outer surface of the third support bar 130.

When the antenna elements are folded like this, the operator can move to the next destination without disassembling.
