Title:
ANTENNA FILTER AND ELECTRONIC DEVICE COMPRISING SAME IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/225419
Kind Code:
A1
Abstract:
The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting higher data transmission rates than 4th generation (4G) communication systems such as Long Term Evolution (LTE). According to various embodiments of the present disclosure, a device for radiating a signal in a wireless communication system comprises: a power amplifier; an antenna; and a coupled filter unit configured to deliver an output signal from the power amplifier to the antenna, wherein the coupled filter unit comprises: a first impedance matching circuit; a second impedance matching circuit; and a plurality of filters connected in parallel between the first impedance matching circuit and the second impedance matching circuit, wherein the allowable power of each of the plurality of filters may be smaller than the maximum output power of the power amplifier.
