Reconfigurable MIMO Antenna Design with High Isolation using Metasurface

In this paper, a frequency reconfigurable multiple-input-multiple-output (MIMO) antenna has been described. The idea of the design is to form reconfigurable MIMO antenna by the development of two-port antenna that are identical to each other and pin diodes are used to achieve the frequency reconfigurability. The design of the canonical element consists of compact folded slots with one pin diode...

Distributed Antenna Systems and MIMO Technology

With the explosive growth in wireless usage due in part to smart phones, tablet computers and a growing applications developer base, wireless operators are constantly looking for ways to increase the spectral efficiency of their networks. Multiple input/ multiple output (MIMO) technology, which made its first broad commercial appearance in 802.11n systems, is now gaining substantial momentum in...

Pattern Reconfigurable Circular Patch Antenna for Mimo Communications

This paper presents a reconfigurable two-port circular patch antenna that improves the performance of a MIMO wireless communications system through pattern diversity. Different modes of the circular patch antenna can be excited by varying its radius with PIN diode switches. Based on this antenna architecture a practical algorithm that exploits the wireless channel spatial selectivity to select ...
