Problems solved by technology

[0004] However, in existing antenna devices using MIMO technology, since the antenna device is designed such that the frequency bands corresponding to the multiple antennas provided in one antenna device are only different from a preset frequency band (for example, 3.5GHz frequency band or One of the 4.5GHz frequency bands), there is a problem that the entire antenna unit needs to be replaced when changing to a different frequency band

Abstract

The present invention relates to an antenna device, and more particularly, to an antenna device comprising: a main case in which an internal space for accommodating a main board is formed and a plurality of heat dissipation fins are provided on the outer surface thereof; a cover housing for shielding the internal space of the main housing and having a plurality of heat dissipation fins on the outer surface thereof; and a plurality of unit antenna blocks which are detachably coupled to the cover case so as to occupy a part of the outer surface of the cover case, and which have one or more antenna devices and an antenna substrate coupled to one or more antenna filters embedded therein. The plurality of unit antenna blocks are in signal connection with the main board by using at least one connection card as a medium, thereby providing the advantages of realizing dual frequency band and effectively performing heat dissipation.

Description

technical field [0001] The present invention relates to an antenna device (ANTENNA APPARATUS), and in more detail, relates to an antenna device capable of realizing dual-banding that can easily double-polarize the frequency bands used. Background technique [0002] Wireless communication technology, for example, Multiple Input Multiple Output (MIMO, Multiple Input Multiple Output) technology is a technology that uses multiple antennas to greatly increase data transmission capacity. Spatial multiplexing (Spatial multiplexing) technology that distinguishes the transmitted data through appropriate signal processing in the device. [0003] Therefore, as the number of transmit and receive antennas increases simultaneously, the channel capacity will also increase, allowing more data to be transmitted. For example, if the number of antennas is increased to 10, compared with the current single-antenna system, about 10 times the channel capacity can be secured using the same frequen...
