Abstract
A communication device is provided. The communication device includes: an antenna; a matching circuit connected with the antenna; a transmitter configured to generate a transmission communication signal and provide the transmission communication signal to the antenna through the matching circuit; a filter connected between the matching circuit and the antenna; and a receiver configured to receive an attenuated signal from the antenna through the filter. The filter is configured to pass frequencies of an antenna signal corresponding to a pass band and attenuate frequencies of the antenna signal corresponding to a stop band, and a center frequency of the transmission communication signal corresponds to the stop band of the filter.
