| 摘要 |
The present invention relates to a polarization selection type antenna apparatus, comprising: an antenna unit having multiple vertical polarization antennas and multiple horizontal polarization antennas; a switch unit, connected to the multiple vertical polarization antennas and the multiple horizontal polarization antennas, for selecting one among the multiple vertical polarization antennas and the multiple horizontal polarization antennas through a switching operation, and a wireless communication unit for providing data to an external apparatus with a wireless communication method preset through an antenna selected by the switching operation of the switch unit. The polarization selection type antenna apparatus according to the present invention can establish a stable communication environment by optimizing a signal transmitted to/from an electronic price displaying apparatus. |
