Abstract

ABSTRACT In the present work, a metamaterial-based insulator is proposed as a mean to achieve both highly compact and loosely coupled array of antennas. Its main working principle is summarized through a general qualitative analysis. The theoretical results are supported by experimental evidences. The chosen operating frequency is 2.4 GHz considering that it is a usual frequency for many indoor wireless applications. © 2017 Wiley Periodicals, Inc.

Abstract

A three-dimensional convex polyhedral beam-tracing method for modeling ultrawideband indoor radio channels is presented.The model enables a fast and unambiguous generation of all propagation paths between the transmitter and the receiver over an 850-MHz bandwidth. To validate the model, its results are compared with measurements. © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 54:904-909, 2012; View this article online at wileyonlinelibrary.com.
