Abstract

A multi-band antenna apparatus according to one of various embodiments of the present invention may comprise: an antenna housing in which an antenna module having two or more frequency bands is mounted; a plurality of repeaters detachably coupled to the antenna housing according to slide movement thereof; connector parts which protrude from the antenna housing and are connected to the plurality of repeaters, respectively; and a bracket which fixes the antenna housing to an outer wall and couples the plurality of repeaters to the antenna housing in an individually detachable manner.

First claim

What is claimed is:

1 . A multi-band antenna apparatus, comprising:
an antenna housing mounting antenna modules with two or more frequency bands; a plurality of relays detachably coupled to the antenna housing as the relays slide; connector portions respectively connected with the plurality of relays and protruding from the antenna housing; and brackets fastening the antenna housing to an outer wall and individually and detachably coupling the plurality of relays to the antenna housing.

2 . The multi-band antenna apparatus of claim 1 , wherein the brackets include fastening brackets provided at an upper and lower side of the antenna housing and fastening the antenna housing to the outer wall and guiding brackets allowing the plurality of relays to be individually and detachably coupled to the antenna housing.

3 . The multi-band antenna apparatus of claim 2 , further comprising guiding parts allowing the relays to be seated, supported, and slid between the guiding brackets and the relays.

4 . The multi-band antenna apparatus of claim 3 , wherein the guiding parts include guiding members provided in the guiding brackets and sliding members provided along surrounding edges of the relays, seated, supported, and slid on the guiding members.

5 . The multi-band antenna apparatus of claim 4 , wherein the relays include a first RRH mounted at a lower portion of a rear surface of the antenna housing and electrically connected with a first antenna module mounted in the antenna housing and a second RRH positioned to neighbor the first RRH at an upper portion of the rear surface of the antenna housing and electrically connected with a second antenna module mounted in the antenna housing.

6 . The multi-band antenna apparatus of claim 5 , wherein the guiding brackets include a first bracket provided on an upper surface of the antenna housing, a second bracket provided on a lower surface of the antenna housing, and a third bracket provided between the first bracket and the second bracket in the antenna housing, wherein a first mount space for mounting the first RRH is provided between the first bracket and the second bracket, and a second mount space for mounting the second RRH is provided between the second bracket and the third bracket.

7 . The multi-band antenna apparatus of claim 6 , wherein the guiding members include a first guiding member provided between the first bracket and the third bracket and guiding a slide of the first RRH and a second guiding member provided between the second bracket and the third bracket and guiding a slide of the second RRH.

8 . The multi-band antenna apparatus of claim 7 , wherein the first bracket includes a first supporting plate mounted in a direction perpendicular to a gravity direction at a lower side of a surface of the antenna housing, wherein the second bracket includes a second supporting plate mounted in a direction perpendicular to the gravity direction at an upper side of a surface of the antenna housing, wherein the third bracket includes a body mounted between the first supporting plate and the second supporting plate, and wherein the first guiding member is provided between the first supporting plate and the body, and the second guiding member is provided between the second supporting plate and the body.

9 . The multi-band antenna apparatus of claim 8 , wherein the first guiding member includes a U-shaped first lower guiding rail provided on an upper surface of the first supporting plate and a reversed U-shaped first upper guiding rail provided on a lower surface of the body and facing the first lower guiding rail with the first mount space positioned therebetween.

10 . The multi-band antenna apparatus of claim 9 , wherein the second guiding member includes a reversed U-shaped second upper guiding rail provided on a lower surface of the second supporting plate and a U-shaped second lower guiding rail provided on an upper surface of the body and facing the second upper guiding rail with the second mount space positioned therebetween.

11 . The multi-band antenna apparatus of claim 10 , wherein the sliding members include first sliding members protruding from an upper and lower surface of the first RRH, seated, supported, and slid on the first upper guiding rail and the first lower guiding rail, respectively and second sliding members protruding from an upper and lower surface of the second RRH, seated, supported, and slid on the second upper guiding rail and the second lower guiding rail, respectively.

12 . The multi-band antenna apparatus of claim 8 , further comprising a shielding plate formed to be inclined inside the body and allowing high-temperature air discharged from an upper side of the first RRH to be introduced into a lower side of the second RRH.

13 . The multi-band antenna apparatus of claim 5 , wherein the connector portions include:
a first connector protruding at a lower portion on a rear surface of a first housing and electrically connecting the first RRH with the first antenna module; and a second connector protruding at an upper portion on a rear surface of a second housing above the first connector and electrically connecting the second RRH with the second antenna module.

14 . The multi-band antenna apparatus of claim 13 , wherein a first connector terminal is provided on a surface of the first RRH to electrically connect with the first connector, and a second connector terminal is provided on a surface of the second RRH to electrically connect with the second connector.

15 . The multi-band antenna apparatus of claim 5 , wherein a first heat-dissipation fin member is provided on an edge of a surface of the first RRH, and a second heat-dissipation fin member is provided on an edge of a surface of the second RRH.
