A Stochastic Approach to Design MIMO Antenna with Parasitic Elements Based on Propagation Characteristics

This paper proposes a channel capacity maximization method for Multiple-Input Multiple-Output (MIMO) antennas with parasitic elements. Reactive terminations are connected to the parasitic elements, and the reactance values are determined to achieve stochastically high channel capacity for the environment targeted. This method treats the S-parameter and propagation channel of the antenna, includ...

Single Front-End MIMO Architecture with Parasitic Antenna Elements

In recent years, wireless communication technology has been studied intensively. In particular, MIMO which employs several transmit and receive antennas is a key technology for enhancing spectral efficiency. However, conventional MIMO architectures require some transceiver circuits for the sake of transmitting and receiving separate signals, which incurs the cost of one RF front-end per antenna...

On-body Antenna with Parasitic Elements

An antenna solution for MIMO channels: the switched parasitic antenna

We investigate the switched parasitic antenna (SPA), which is a novel technique for electronically directing the radiation pattern, in a MIMO system. The correlation between the received signal modes are shown to be sufficiently low to yield a diversity gain. The capacity limit using the SPA is investigated for different SPA configurations and it is found that the capacity is comparable with an...

Evaluating the deformation monitoring capability of a ground based SAR system with MIMO antenna

By increasing the applicability of ground-based SAR (GBSAR) systems in geoscience and remote sensing, the development and evaluation of new systems have gained attention. GBSAR systems can be utilized for monitoring areas that are hard to or cannot be seen by the airborne or spaceborne systems. Furthermore, they have better spatial and temporal resolutions and are cost-effective and easy to imp...
