TRI-BAND GLASS ANTENNA DEVICE FOR PUBLIC TRANSPORTATION VEHICLE

摘要

The present invention relates to a tri-band glass antenna device for a public transportation vehicle, which can implement a CDMA (824 to 896MHz) antenna used for mobile communication in a terminal, a GPS (1563 to 1587 MHz) antenna for location information confirmation in a navigation device, and a Wi-Fi (2.4 to 2.48 GHz) antenna applied to an access point (AP) and using the Internet in a signal range of the AP in the public transportation vehicle as a single glass antenna. The tri-band glass antenna device includes a multiband antenna receiving or transmitting a plurality of different band signals; a band extracting unit extracting the multiband signals received from the multiband antenna by each band; a CDMA signal processing unit processing a received signal in a CDMA band extracted by the band extracting unit and transmitting the processed signal to a CDMA system; a GPS signal processing unit processing a received signal in a GPS band extracted by the band extracting unit and transmitting the processed signal to a GPS system; and a Wi-Fi signal processing unit processing a received signal in a Wi-Fi band extracted by the band extracting unit and transmitting the processed signal to a Wi-Fi system.;COPYRIGHT KIPO 2016
