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, within which antenna modules with two or more frequency bands are mounted;
fastening brackets provided at an upper and a lower sides of the antenna housing for fastening the antenna housing to an outer wall;
guiding brackets provided on a rear surface of the antenna housing, wherein the guiding brackets include guiding members;
a plurality of radio remote heads (RRHs) configured to be slidably coupled to the guiding brackets of the antenna housing along the guiding members; and
connector portions that protrude from the rear surface of the antenna housing and are movable in a direction perpendicular to the rear surface of the antenna housing for connecting the plurality of RRHs,
wherein the guiding members are configured to slidably guide the RRHs along a lateral direction parallel to the rear surface of the antenna housing into spaces between the rear surface of the antenna housing and the fastening brackets,
wherein the guiding members include a first guiding member provided between a first bracket of the guiding brackets and a third bracket of the guiding brackets for slidably guiding a first RRH of the RRHs and a second guiding member provided between a second bracket of the guiding brackets and a third bracket of the guiding brackets for slidably guiding a second RRH of the RRHs,
wherein the first guiding member includes a U-shaped first lower guiding rail provided on an upper surface of a first supporting plate of the first bracket and a reversed U-shaped first upper guiding rail provided on a lower surface of a body of the third bracket and facing the first lower guiding rail, and wherein a first mount space of the guiding bracket is defined between the first lower guiding rail and the first upper guiding rail, and
wherein the second guiding member includes a reversed U-shaped second upper guiding rail provided on a lower surface of a second supporting plate of the second bracket and a U-shaped second lower guiding rail provided on an upper surface of the body of the third bracket and facing the second upper guiding rail, and wherein a second mount space of the guiding bracket is defined between the second upper guiding rail and the second lower guiding rail.

2. The multi-band antenna apparatus of claim 1 , wherein each of the RRHs includes sliding members provided along surrounding edges of the RRHs, configured to be slidably inserted into the guiding members of the guiding brackets.

3. The multi-band antenna apparatus of claim 2 , wherein the RRHs include the first radio remote head (RRH) mounted at a lower portion of the rear surface of the antenna housing and electrically connected with a first antenna module within the antenna housing and the second RRH disposed adjacent to the first RRH at an upper portion of the rear surface of the antenna housing and electrically connected with a second antenna module within the antenna housing.

4. The multi-band antenna apparatus of claim 3 , wherein the guiding brackets include the first bracket provided on a lower surface of the antenna housing, the second bracket provided on an upper surface of the antenna housing, and the third bracket provided between the first bracket and the second bracket in the antenna housing, wherein the first mount space for mounting the first RRH is provided between the first bracket and the third bracket, and the second mount space for mounting the second RRH is provided between the second bracket and the third bracket.

5. The multi-band antenna apparatus of claim 4 , wherein the first bracket includes the first supporting plate mounted in a direction perpendicular to a gravity direction, wherein the second bracket includes the second supporting plate mounted in the direction perpendicular to the gravity direction, wherein the third bracket includes the body, 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.

6. The multi-band antenna apparatus of claim 5 , wherein the sliding members include first sliding members protruding from an upper and a lower surfaces 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 a lower surfaces of the second RRH, seated, supported, and slid on the second upper guiding rail and the second lower guiding rail, respectively.

7. The multi-band antenna apparatus of claim 5 , further comprising a shielding plate formed to be inclined inside the body and preventing high-temperature air discharged from an upper side of the first RRH from being introduced into a lower side of the second RRH.

8. The multi-band antenna apparatus of claim 3 , 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.

9. The multi-band antenna apparatus of claim 8 , 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.

10. The multi-band antenna apparatus of claim 3 , 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.
