A transceiver circuit includes a duplexer having a transmit band for transmit signals and a receive band for receive signals, and an antenna circuit electrically connected to the duplexer. The antenna circuit is configured to generate at least one stop band in a frequency range in which noise signals are received. An intermodulation product of the noise signals and the transmit signals is in the receive band of the transceiver circuit.
