DUPLEXER HAVING MICROSTRIP LINE STRUCTURE

摘要

PURPOSE: A duplexer having a microstrip line structure is provided to prevent the interference of a receiving section and a transmitting section by regulating the resonance. CONSTITUTION: An antenna(110) is located at the central portion of the duplexer. A receiving resonator(120) transmits the wave which is received through the antenna(110) to a receiving section. A transmitting resonator(130) transmits the transmitting wave to the antenna(110). The receiving resonator(120) is designed such that the resonance is generated at the central frequency of the receiving section, and the transmitting resonator(130) is designed such that the resonance is generated at the central frequency of the transmitting section.
