Accordingly, since all of the rear surfaces of the main board 310 and the sub-board 320 are in thermal surface contact with the inner surface of the rear heat dissipation housing 200 , it has the advantage of greatly improving the heat dissipation performance.

On the other hand, as shown in FIGS. 8A and 8B , the shielding pad 330 may be laminated and coupled to the remaining portion of the front surface of the main board 310 , except for the portion occupied by the plurality of filters 350 .

Such a PSU unit 400 includes a PSU substrate 410 and a plurality of electronic elements 419 including a plurality of PSU elements 417 disposed on either the front or rear surface of the PSU substrate 410 . can do.

The PSU unit 400 may be provided to distribute power to the main board 310 via a plurality of bus bars 340 . More specifically, the plurality of bus bars 340, as shown in FIGS. 6A and 6B and FIG. 9 , respectively, interconnect the left and right ends of the PSU substrate 410 and the main board 310 to each other. In particular, the plurality of bus bars 340 may be connected by an operation of being inserted into the connection hole 319 previously formed in the main board 310 .

Accordingly, heat generated from the PSU element 417 and the electric element 419 of the PSU unit 400 may be rearwardly radiated using the rear heat dissipation housing 200 as a heat transfer medium.

However, it is not necessarily provided so that the heat generated from the PSU unit 400 is dissipated to the rear through the rear heat dissipation housing 200, and although not shown, a vapor chamber or heat pipe structure provided separately as a heat transfer medium forward It will be understood that it is also possible to be provided so as to radiate heat forward toward the heat dissipation housing 100 . This is because, in the case of the antenna device 1 according to an embodiment of the present invention, unlike the case in which a conventional radome is provided, the front heat dissipation through the front heat dissipation housing 100 has an advantageous structure.

10 is an exploded perspective view for explaining the coupling of the filter to the main board in the configuration of FIG. 2, and FIG. 11 is the heat generated from the filter in the configuration of FIG. It is a partially cut-away perspective view.

As described above with respect to the front and rear surfaces of the main board 310, when the shielding pad 330 and the sub-board 320 are respectively stacked, as shown in FIGS. 10 and 11, a plurality of filters as an RF filter (350) is mounted on the front surface of the main board (310).

At this time, the plurality of filters 350 are cavity filters provided with a clamshell integrally at the rear end of each, and are inserted into the filter assembly holes 317 formed in the main board 310 at the portions where the clamshells are formed to assemble. At least one filter assembling protrusion 357 is formed for the purpose, and the filter assembling protrusion 357 may be formed in a tube shape with an empty interior.

Accordingly, the heat generated from the LNA element 312 and the PA element 322 in the air layer between the rear end of each of the plurality of filters 350 and the main board 310 and collected is a tube-shaped filter assembly protrusion 357 . And it is possible to easily dissipate heat toward the rear heat dissipation housing 200 through the heat dissipation via hole 357a formed in the main board 310 .

On the other hand, at the rear end of the plurality of filters 350, a pair of mainboard side coaxial connectors 353a electrically connected to the power supply connector 360 mounted on the main board 310 is provided, and a plurality of filters 350 are provided. A pair of antenna-side coaxial connectors 353b electrically connected to the antenna module 110 disposed on the front surface of the front heat dissipation housing 100 may be provided at the front end of the .

In addition, a thermal pad 109 that mediates heat transfer to the rear surface of the front heat dissipation housing 100 is disposed at the front end of the plurality of filters 350 , and heat generated from each of the plurality of filters 350 is transferred to the front heat dissipation housing (100) is used as a heat transfer medium so that the front heat can be dissipated more quickly.

In addition, a screw fastening hole 359 for screw coupling using a set screw 351 to the front heat dissipation housing 100 is formed at the front end of the plurality of filters 350 , and the set screw 351 is a front heat dissipation The front heat dissipation housing 100 may be laminatedly coupled to the front surface of the plurality of filters 350 by passing through the screw through hole 119 formed in the housing 100 and being fastened to the screw fastening hole 359 .

According to the above configuration, the heat generated by the filter 350 is directly in contact with the rear surface of the front heat dissipation housing 100 or the radiation director 117 during the configuration of the antenna module 110, so that the heat of the filter 3500 is It was confirmed that the effect of about 14 ~ 16 ℃ lower than that of the prior art. This is not only the effect of the deletion of the radome, which was a conventional element of heat dissipation, but also the direct heat transfer (heat conduction) to the rear surface of the front heat dissipation housing 100 made of a material suitable for dissipating the heat of the filter 350 and the director 117 for radiation. It is understood that the effect of improving the heat transfer performance through

It is a front view of the antenna module during construction and a cross-sectional view and a cut-away perspective view taken along line BB.

In order to implement beamforming, as shown in FIGS. 14 to 18 , a plurality of radiating elements are required as an array antenna, and a plurality of radiating elements are narrow directional beams. Can be created to increase the concentration of radio waves in a specified direction. Recently, a plurality of radiating elements, dipole-type dipole antenna (Dipole antenna) or patch-type patch antenna (Patch antenna) is utilized with the highest frequency, and is designed and arranged to be spaced apart to minimize the signal interference between each other. Conventionally, in general, in order to prevent the arrangement design of such a plurality of radiating elements from being changed by external environmental factors, a radome for protecting the plurality of radiating elements from the outside is essential. Therefore, only in the area covered by the radome, the antenna board on which the plurality of radiating elements and the plurality of radiating elements 130 are installed is not exposed to the outside air, so that the system heat generated due to the operation of the antenna device 1 is transferred to the outside. Heat dissipation was very limited.

The radiating element 117 of the antenna device 1 according to an embodiment of the present invention includes an antenna patch circuit 116 and It is formed of a conductive metal material and includes a radiation director 117 electrically connected to the antenna patch circuit unit 116 . An antenna patch circuit unit 116 is printed on the printed circuit board 115 for the radiating element, and it is provided as a double polarization patch element that generates either a double polarized wave of either ±45 orthogonal polarization or vertical/horizontal polarization. On the upper surface of the printed circuit board 115 for a radiating element, a feed line (not shown) for supplying a feed signal to the antenna patch circuit unit 116 is patterned to interconnect each of the antenna patch circuit units 116 .

In the conventional antenna device, the feeding line has to form a feeding line at the lower part of the printed circuit board on which the antenna patch circuit unit is mounted. It occupies the lower space of the circuit board 115, and there is a problem that acts as an element that prevents direct surface thermal contact between the filter 350 and the printed circuit board 115 for the radiating element, but in the embodiment of the present invention The feeding line according to the pattern printing is formed on the same front surface as the printed circuit board 115 for the radiating element on which the antenna patch circuit unit 116 is pattern-printed, thereby simplifying the feed structure as well as printing the filter 350 and the radiating element. There is an advantage in that it is possible to secure a bonding space that is in direct thermal contact with the surface on the circuit board 115 .

Meanwhile, the radiation director 117 is formed of a thermally conductive or conductive metal material and is electrically connected to the antenna patch circuit unit 116 . The radiation director 117 may perform a function of guiding the radiation beam in a forward direction and simultaneously transferring heat generated from the rear of the printed circuit board 115 for a radiation element forward through heat conduction. The radiation director 117 may be made of a metal of a conductive material through which radio waves flow well, and is installed to be spaced apart from the upper portion of each antenna patch circuit unit 116 .

Here, the height of the heat dissipation unit 105 (heat dissipation fin) of the front heat dissipation housing 100 may be set as much as the height of the radiation director 117 coupled to the antenna module cover 111 to be described later.

In the embodiment of the present invention, the radiation element using the antenna patch circuit unit 116 and the radiation director 117 has been described. However, when a dipole antenna is applied, the configuration of the radiation director can be omitted, and the height of the dipole antenna is relatively high. It is possible to increase the amount of heat dissipation by setting the height of the heat dissipation unit 105 (heat dissipation fin) to be high as much as possible.

The overall size, shape, and installation location of the radiation director 117 may be appropriately designed by measuring the characteristics of the radiation beam radiated from the corresponding antenna patch circuit unit 116 and experimentally or by simulating the corresponding characteristics. The radiation director 117 serves to guide the direction of the radiation beam generated by the antenna patch circuit unit 116 in all directions, further reducing the beam width of the entire antenna and improving the characteristics of the side lobe. In addition, it is possible to compensate for the loss due to the patch-type antenna and to perform a heat dissipation function as it is made of a conductive metal. The shape of the radiation director 117 is preferably, but not limited to, an appropriate shape for guiding the direction of the radiation beam in an omni-direction, for example, a circular shape having non-directionality.
