The article focuses on the design, measurement, and simulation of a new Long Term Evolution (LTE) downlink mode in which the polarization diversity replaces the spatial diversity at the user equipment (UE). The proposed system enables the analysis of the circularly polarized (CP) antenna over the multipath SISO channel. The purpose of the article is to design a compact LTE SISO system capable of providing comparable performance to the one with spatial diversity (SIMO 1 × 2). In this respect, the entire process is described from antenna designing and measurements to the final stage of integration and simulation. The results indicate the necessity of taking into account the effect of the polarization diversity to keep up the data rate for the small LTE devices when spatial diversity is not an option. The new system proves valuable to evolve toward new downlink modes suitable especially for tiny devices yet capable of achieving high data rates. The article envisages some new processing stages at the UEs as well as at the base station (eNodeB) for CP usage. © 2016 Wiley Periodicals, Inc. Int J RF and Microwave CAE 26:547–558, 2016.
