APPARATUS FOR SHARING A 3-BAND INTENNA

摘要

An apparatus for sharing a 3-band single intenna is provided to reduce the loss of a signal transmission path by being embodied by using a switch unit and a diplexer, and transmitting/receiving signals of 3 frequencies through one intenna. A diplexer(130) connects to a communication module of the first frequency and a communication module of the second frequency, and separates two signals so that signals of the first frequency and the second frequency share one communication path. A switch unit(120) connects a communication path between an intenna(110) and the diplexer(130), or connects a communication path between the intenna(110) and a communication module of the third frequency.
