摘要： The disclosure relates to a communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with an IoT technology. The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety-related services. The disclosure provides a mixer including a first impedance connected in parallel to a mixer output transformer and configured to remove a primary local frequency component generated at an output of the mixer, and a second impedance connected in parallel to the mixer output transformer and configured to remove a secondary local frequency component generated at the output of the mixer, wherein the first impedance operates as a series resonator in a primary local frequency band, and the second impedance operates as a parallel resonator in a secondary local frequency band.

摘要： The present disclosure relates to a communication technique for converging Internet of Things (IoT) technology with a 5 th Generation (5G) communication system for supporting a higher data transfer rate beyond a 4 th Generation (4G) system, and a system therefor. The disclosure can be applied to intelligent services (e.g., smart homes, smart buildings, smart cities, smart or connected cars, health care, digital education, retail business, and services associated with security and safety) on the basis of 5G communication technology and IoT-related technology. An antenna module is provided. The antenna module includes an antenna, and at least one transmission line configured to transmit a first signal through the antenna for transmission or receive a second signal through the antenna for reception. The length of the transmission line may be determined based on the impedance seen from the antenna through the transmission line when the first signal or the second signal flows through the transmission line.
