Transmission line structure having a signal line spaced apart from ground by an air layer and the signal line is supported at a center part thereof

Abstract

The disclosure relates to a pre-5-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4-Generation (4G) communication system such as Long Term Evolution (LTE). A transmission line structure of a wireless communication system is provided. The transmission line includes a ground area, a signal line, and a support. A first surface of the signal line is disposed to be spaced apart from the ground area via an air layer therebetween, a second surface of the signal line located opposite to the first surface may be coupled to the support, and the support may be coupled to the ground area.
