Abstract:The aim of this paper is to present the experimental characterization of a reconfigurable parasitic patch antenna for Multiple Input Multiple Output (MIMO) applications. The proposed antenna is able to work with two different polarizations, providing separate control of the antenna pattern of each of the two polarizations. Both numerical and experimental results show the adaptive capabilities of the antenna, proving its effectiveness for MIMO applications.

“…Since the channel is not stationary, it is interesting that each antenna of the MIMO system can switch between different radiation pattern configurations in order to optimize the channel capacity. Consequently, a reconfigurable antenna used as one of multiple radiating elements offers an additional degree of freedom for MIMO communications [1].…”

Abstract-Wideband collocated antennas for multiple input multiple output (MIMO) systems are proposed. The structure is disposed on two substrate layers. On the first top substrate, a disc monopole is etched. The top of the second substrate contains a tapered slot antenna in a form of a Vivaldi antenna and two reflector elements in the form of half disc. The designed antenna can switch among five radiation patterns which radiate in different directions of space with only two excitation ports. All antennas have a relative bandwidth at least 23%. The antenna elements exhibit a low mutual coupling since they are around −17 dB over the considered bandwidths. This performance is believed because the disc monopole mainly has a broadside radiation while the Vivaldi antenna radiates in end-fire directions. With an overall length of about a half guided wavelength, the proposed structure is believed suitable for applications needing radiation pattern diversity.

“…Recent research in this area has either focused on adaptive antenna systems such as pattern reconfigurable antennas [1][2][3][4][5][6][7][8] or adaptive physical layer (PHY) techniques such as link adaptation [9][10][11][12][13] to enhance data rates.…”

“…Although several works [3,4,8] have demonstrated the benefits of reconfigurable antennas, translating the benefits of these antennas into a practical realizable MIMO communication system is very challenging. The cost of integrating and implementing the functionality of the reconfigurable antennas into the system and their complexity of operation have inhibited the process of integration.…”

In this work, we study and analyze the performance of physical layer algorithms for adaptive multiple input-multiple output orthogonal frequency-division multiplexing (MIMO-OFDM) wireless systems that employ a new class of adaptive antenna systems known as reconfigurable antennas. These antennas are capable of adaptively modifying their radiation characteristics and thus leverage pattern diversity to affect how the transmitter and receiver perceive the wireless channel. We propose a low complexity spatial adaptive modulation and coding (AMC) algorithm that uses the advantages of pattern reconfigurable antennas in concert with link adaptation to improve MIMO-OFDM link throughput. The algorithm operates in two main stages; first, it searches for the antenna configuration that yields the highest post processing signal-to-noise ratio (ppSNR) and, then, applies AMC to improve spectral efficiency. The performance of the proposed scheme is experimentally evaluated for a 2 × 2 MIMO-OFDM wireless system in an indoor environment.
