A dual-band CPW antenna designed for WLAN communication in cabin

A dual-band monopole antenna fed with a coplanar waveguide (CPW) for wireless local area network (WLAN) communication in cabin is proposed in this paper. The antenna comprises an elliptical metallic patch as the monopole and a CPW as its feeding line. The simulated results demonstrate that the proposed antenna just covers the WLAN bands (2.4-2.485, 5.15-5.35 and 5.725-5.825 GHz) with good omnidirectional radiation patterns, which satisfy the requirements of WLAN applications. However, in multipath environment like the cabin of an airplane, the performance of the antenna will be influenced. Thus, a reverberation chamber (RC) is devoted to simulate the cabin environment because it can effectively form a uniform multipath propagation environment. In this work, the effects of the chamber on antenna radiation performance have been studied with scattering parameters (S-parameters). Furthermore, an alternative method is provided to investigate the environment of radiation posed by antennas for WLAN communication inside the chambers like the cabin of airplanes or trains.
