Disclosed is a common antenna apparatus capable of processing transmission/reception signals of various frequency bands by a single common antenna, by connecting a filter circuit or resonance circuit to a specific position of the single common antenna so as to process the transmission/reception signals. The common antenna apparatus comprises a common antenna having a length sufficient for processing all frequency bands for mobile communication services, and a band extractor located at a specific position of the common antenna in a length direction of the common antenna so as to transmit/receive signals of a specific frequency band, thereby extracting the signals of the specific frequency band. |
